Field of the Invention This invention relates generally to Bit Rate Agile (BRA) signal processors; more particularly to cross-correlated signal processors for increasing RF spectral and power efficiency of modulated transmitted signals including but not limited to digital binary, digital multilevel, and/or analog modulated signals operated in linearized and in power-efficient Non-Linearly Amplified (NLA) systems; and most particularly to BRA and RF Agile Cascaded Time Constrained Signal (TCS) response and Long Response (LR) filtered and Mis-Matched (MM) filtered (ACM) quadrature phase, frequency and amplitude modulated Transmitter, Receiver, and Transceiver systems having these characteristics and methods and procedures provided thereby. BACKGROUND OF THE INVENTION The most important objectives of wireless communications, broadcasting, telemetry, infrared and in general "radio" systems as well as "wired" systems include: power and bandwidth or spectrum efficiency combined with robust Bit Error Rate (BER) performance in a noisy and/or strong interference environment . These system objectives are specified in numerous systems including wireless communications and cellular systems, satellite systems, mobile and telemetry systems, broadcasting systems, cable, fiber optics and practically all communication transmission systems. A partial list of publications, references, and patents are provided separately below. The cited publications, references [1-23] and patents [P1-P8], and the references within the aforementioned publications contain definitions and descriptions of many terms used in this new patent disclosure and for this reason these conventional terms and definitions will be described only briefly, and highlighted on a case by case basis. Robust or high performance Bit Error Rate (BER) specifications and/or objectives are frequently expressed in terms of the required BER as a function of Energy per Bit (Eb) divided by Noise Density or simply noise (No), that is, by the BER=f (Eb/No) expression. Low cost, reduced size, and compatibility and/or interoperability with other conventional or previously standardized systems, also known as "legacy systems," are highly desired. Several standardization organizations have adopted modulation techniques such as conventional Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), Offset Quadrature Phase Shift Keying (OQPSK) also designated as Staggered Quadrature Phase Shift Keying (SQPSK), and pi/4-QPSK (or π/4-QPSK) techniques including differential encoding variations of the same. See publications [1 -23] and referenced patents [P1-P8] for examples and further description. For spectrally or spectrum efficient signaling (such as band-limited signaling), these conventional methods exhibit a large envelope fluctuation of the modulated signal, and thus have a large increase in peak radiated power relative to the average radiated power. For these reasons such systems are not suitable for BRA, robust BER performance NLA operated RF power efficient systems. Within the present state of the technology, for numerous BRA Transceiver applications, it is not practical to introduce band-pass filtering after the NLA power efficient Radio Frequency (RF) final amplifier stage. Here we are using the term "Radio Frequency" (RF) in its broadest sense, implying that we are dealing with a modulated signal. The RF could be, for example, as high as the frequency of infrared or fiber optic transmitters; it could be in the GHz range, for example, between 1 GHz and 300 GHz or more, or it could be in the MHz range, for example, between about 1 MHz and 999 MHz, or just in the kHz range. The term RF could even apply to Quadrature Modulated (abbreviated "QM" or "QMOD") Base-Band (BB) signals or to Intermediate Frequency (IF) signals. In conventional BPSK, QPSK, OQPSK or SQPSK, and differentially-encoded phase-shift keying systems variants of these systems, such as DBPSK and DQPSK, as well as in pi/4-DQPSK and trellis coded QPSK and DQPSK, large envelope fluctuations require linearized (LIN) or highly linear transmitters including frequency up-converters and RF power amplifiers and may require expensive linear receivers having linear Automatic Gain Control (AGC) circuits. A transmitter NLA reduces the time domain envelope fluctuation of conventional QPSK type of band-limited signals and this reduction of the envelope fluctuation, being a signal distortion, is the cause of spectral restoration or spectral regrowth and the cause of unacceptably high levels of out-of-band spectral energy transmission, also known as out-of-band interference. Additionally, for conventional BPSK, QPSK, and also Quadrature Amplitude Modulation number (QAM) signals, undesired inphase channel (I) to quadrature channel (Q) crosstalk is generated. This crosstalk degrades the BER=f(E b /N 0 ) performance of the modulated radio transmitter. Experimental work, computer simulation, and theory documented in many recent publications indicates that for band-limited and standardized BPSK, QPSK, OQPSK or SQPSK or pi/4-QPSK, and QAM system specifications, very linear amplifiers are required to avoid the pitfalls of spectral restoration and of BER degradation. Linearized or linear amplifiers are less RF power efficient (during the power "on" state, power efficiency being defined as the transmit RF power divided by DC power), are considerably more expensive and/or having less transmit RF power capability, are larger in size, and are not as readily available as NLA amplifiers. The advantages of NLA over LIN amplifiers are even more dramatic at higher RF frequencies, such as frequencies above about 1GHz for applications requiring low dc voltage, for example applications or systems operating on size "AA" batteries having only 1.5 Volt dc and for high RF modulated power requirements, for example transmit RF power in the 0.5 Watt to 100 Watt range. Published references [P1 to P8] and [1 to 23] include additional background information. These references include descriptions of binary-state and multiple-state Transmitter/Receiver (Transceiver) or for short ("TR") systems that are suitable for NLA. In the aforementioned references Processors, Modems, Transmitters, Receivers and Transceivers, suitable for NLA, have been described, defined and designated as first generation of Feher patented Quadrature Shift Keying (FQPSK). For example, in reference [22] published on May 15, 1999 the authors Drs. M.K. Simon and T.Y. Yan of JPL/NASA-Caltech present a detailed study of Unfiltered Feher- Patented Quadrature Phase Shift Keying (FQPSK). In references [1-22] and patents #[P1-P8] numerous first generation FQPSK technology based terms, and terms other than the FQPSK abbreviation/acronym have been used. In addition to FQPSK Transceivers, these first generation of systems have been also described and/or defined as: Feher's Minimum Shift Keying (FMSK), Feher's Frequency Shift Keying (FFSK), Feher's Gaussian Minimum Shift Keying (FGMSK), Feher's Quadrature Amplitude Modulation (FQAM) and/or Feher's (F) Modulation/Amplification (FMOD). Additionally terms such as Superposed Quadrature Amplitude Modulation (SQAM), Intersymbol Interference and Jitter Free (IJF) and/or IJF-OQPSK have been also described in Feher et al.'s prior patents and publications, each of which is incorporated by reference. In the cited patents and other references, among the aforementioned abbreviations, acronyms, designation, terms and descriptions the "FQPSK" abbreviation/term has been most frequently used to describe in most generic terms one or more of these afore described Feher or Feher et al. first generation of Non-Linearly Amplified (NLA) inventions and technologies. The 1st generation of FQPSK systems have significantly increased spectral efficiency and enhanced end- to-end performance as compared to other NLA systems. RF power advantages, robust BER performance, and NLA narrow spectrum without the pitfalls of conventional BPSK and DBPSK, QPSK and OQPSK have been attained with these 1 st generation FQPSK systems and methods. The generic 1 st generation terms such as FQPSK, as well as other previously mentioned terms/acronyms are retained and used in this description to describe the new BRA, Code Selectable (CS), Modem Format Selectable (MFS) and modulation-demodulation Mis-Matched (MM) filtered architectures and embodiments of "2 nd generation" FQPSK Transceivers. While these earlier issued patents and publications describe material of a background nature, they do not disclose the original new enhanced performance bit rate agile and modulation agile/selectable technologies disclosed in this new invention.

SUMMARY OF THE INVENTION This invention includes disclosure of new and/original spectral efficient and RF power efficient-high performance technologies, new architectures, embodiments and new Bit Rate Agile (BRA) implementation of 2 nd generation FQPSK Transceivers. These inventive structures, methods, and technologies are suitable for a large class of implementations and applications. Numerous embodiments of the inventive structures and methods are enabled. These include cost effective solutions for BRA, Modulation and Demodulation (Modem) Format Selectable (MFS) and Coding Selectable (CS) processors, modulators/demodulators, Transceivers, having agile/ tunable RF frequency embodiments and are suitable for power efficient NLA systems. The terms abbreviations and descriptions used in the 1 st generation of Feher et. al inventions, highlighted in the "Background of the Invention" section, as well as other previously identified terms/acronyms and abbreviation and in particular FQPSK and related terms, used in the cited references, are retained and/or slightly modified and are used relative to this disclosure of the new invention to describe second generation "2 nd generation" BRA architectures and embodiments of FQPSK, FGMSK and FQAM Transceivers. This disclosure contains embodiments for further significant spectral savings and performance enhancements, and new functions and architectures, which were not, included in the referenced prior art patents, inventions and publications. BRA or "Bit Rate Agile" abbreviation and term describes technologies, implementations, embodiments suitable for design, use and applications in which the information rate, source rate, or the often used alternative terms "bit rate", "symbol rate", or "data rate" may be selectable or programmable by the user or by one or more control signal(s). Bit Rate Agile (BRA) systems may be programmable by software or have predetermined or "selectable," i.e., "agile" bit rate applications. The term "bit rate agility" refers to variable and/or flexible selectable bit rates (again bit rate, symbol rate, data rate, information rate, source rate, or equivalent); the bit rates could be selected on a continuous fashion in small increments and/or in steps. These systems are designated as BRA (or Bit Rate Agile) systems. BRA, MFS, and CS systems requirements are increasing at a rapid rate. Changeable (or variable, or selectable) amounts of cross-correlation between Time Constrained Signal (TCS) response processors and/or combined TCS and Long Response (LR) processor and/or post processor filters of in-phase (I) and quadrature (Q) phase signals of BRA Transceivers, MFS and CS baseband signal processing implementations and architectures for tunable RF frequency embodiments having enhanced spectral efficiency and end-to-end performance are disclosed. These new BRA, MFS and CS classes of FQPSK signal processors, modems and transceivers, with Adaptive Antenna Arrays (AAA) and RF power efficient amplifiers and entire Transceivers, operated in fully saturated or NLA mode, with intentionally Mis-Matched (MM) modulation and demodulation filters, transmit BRA and receive BRA filters/processors, disclosed herein, attain high performance advantages and significant spectral savings. A changeable amount of cross-correlation between the BRA and MFS Time Constrained Signal (TCS) response processor and/or combined TCS and Long Response (LR) processor and/or post processor filters of the transmitter with selectable MM between the BRA transmitter and BRA receiver and CS processors, including single and separate in-phase (I) and quadrature (Q) signal storage/readout generators and single and/or separate I and Q channel D/A architectures and a bank of switchable filters for cross-correlated BRA, MFS and CS formats are also disclosed. These new classes of 2 nd generation of FQPSK signal processors, modems and transceivers, with Adaptive Antenna Arrays (AAA) and RF power efficient amplifiers and entire Transceivers, operated in BRA, MFS and CS fully saturated NLA mode, or with LIN mode with intentionally Miss-Matched (MM) transmit BRA and receive BRA filters/processors, disclosed herein, have robust performance and significant spectral saving advantages. In addition to digital embodiments, BRA analog cross-correlation implementations and combined digital-analog active and passive processors, for 2 nd generation FQPSK Transceivers are also disclosed. Subsets, within the generic 2 nd generation of the FQPSK family of processors, modems and transceivers are also designated as 2 nd generation BRA Feher's Minimum Shift Keying (FMSK), Feher's Gaussian Minimum Shift Keying (FGMSK), Feher's Frequency Shift Keying (FFSK) and Feher's Quadrature Amplitude Modulation (FQAM). Switched BRA, selectable Cross-Correlation (CC or Xcor) transmit and receive bandwidth Mis-Matched (MM) low-pass, band-pass and adaptive filter means and controller circuits and algorithms for preamble contained and differentially encoded and/or Forward Error Correction (FEC) with Redundant and Pseudo-Error (PE) based Non Redundant Detection (NED) implementations for FQPSK are also described. The term "Mis-Matched" (MM) designates an intentional and substantial mis-match (MM) between the bandwidth and/or frequency or phase response of modulator filters and demodulator filters and/or mis-match (MM) between one or more implemented FQPSK filter(s) and the theoretical optimal performance minimum bandwidth Nyquist filters. The term "Agile Cascaded Mis-Matched" (ACM) designates the BRA and RF agile ("flexible" or "tunable" RF frequency) cascaded TCS response and LR processor/filter(s) which are mis-matched within their respective application and/or use within this invention. For NLA and for LIN amplifiers, selectable FQPSK filtering strategies in the transmitter and separately in the receiver lead to further spectral efficiency enhancements. Fast synchronization systems and robust efficient adaptive equalizers/adaptive switched systems are also disclosed. The inventive structure and method includes transmit elements, receive elements, and transmit and receive elements, and may be applied to a variety of communication applications, including, but not limited to, wireless communications and cellular systems, satellite systems, mobile and telemetry systems, broadcasting systems, cable system, fiber optic systems, and more generally to nearly all communication transmission and/or receiving systems. In one embodiment of the invention, a bit rate agile communication system is provided and includes a splitter receiving an input signal and splitting the input signal into a plurality of baseband signal streams, and a baseband signal processing network receiving the plurality of baseband signal streams and generating cross-correlated cascaded processed and filtered bit rate agile (BRA) in-phase and quadrature-phase baseband signals. In another embodiment, a quadrature modulator receiving and quadrature modulating the cross-correlated filtered in-phase and quadrature-phase baseband signals to generate a quadrature modulated output signal is also provided. In another embodiment, the baseband signal processing network includes a cross- correlator and at least one bit rate agile cascaded mis-matched (ACM) modulator filter. In yet another embodiment, the invention provides a bit rate agile communication system including a baseband signal processing network receiving parallel baseband signal streams and generating combined Time Constrained Signal (TCS) response and Long Response (LR) filtered in-phase and quadrature-phase baseband signals. In a variation of this embodiment, the inventive structure also includes a quadrature modulator receiving and quadrature modulating the Time Constrained Signal (TCS) response and Long Response (LR) filtered in-phase and quadrature-phase baseband signals to generate a quadrature modulated bit rate agile output signal. In still another aspect, the invention provides a method for generating bit rate agile signals in a communication system. The method includes the steps of processing a plurality of signal streams to generate cross-correlated signals having changeable amounts of filtering for bit rate agile in-phase and quadrature-phase baseband signals. The inventive method may also include the step of receiving an input signal and converting the input signal into the plurality of signal streams. It may also optionally include the further step of modulating the cross-correlated filtered in-phase and quadrature-phase baseband signals to generate a quadrature modulated bit rate agile output signal. In yet another aspect, the invention provides a method for generating bit rate agile signals in a signal transmission system, where the method includes the steps of receiving a plurality of signal streams, processing the plurality of signal streams to generate cascaded Time Constrained Signal (TCS) response and Long Response (LR) filtered in-phase and quadrature-phase baseband signals; and modulating the Time Constrained Signal (TCS) response and Long Response (LR) filtered in-phase and quadrature-phase baseband signals to generate a quadrature modulated bit rate agile output signal. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram depicting an Agile Cascaded Mis-Matched (ACM) enhanced spectral efficiency, high performance Transmitter/Receiver (Transceiver) block diagram for a generic class of modulated systems. FIG. 2 shows an Agile Cascaded Mis-Matched (ACM) implementation block diagram embodiment of this invention with cascaded, switched transmit (Tx) and receive (Rx) Low-Pass- Filters (LPF) for BRA applications in conjunction with Cross-Correlated and other non-cross- correlated cascaded Time Constrained Signal (TCS) response processors and Long Response (LR) filters having substantially Mis-Matched (MM) modulation and demodulation filters. FIG. 3 is an alternate embodiment- block diagram of the current invention, including Cross-Correlator in cascade with a 2 nd processor and with Digital to Analog (D/A) converters followed by spectral and pulse shaping bit rate agile LR filters, implemented by Low-Pass-Filters (LPF) in the I and Q channels of this Quadrature modulator. FIG. 4 shows the implementation of an alternate Quadrature Modulator (QM) Transceiver having one or more Intersymbol-lnterference and Jitter Free (IJF), Superposed Quadrature Amplitude Modulation (SQAM) or TCS response cascaded with LR response filter embodiments in the I and Q transmit Baseband Processor (BBP). FIG. 5 illustrates a Non Return to Zero (NRZ) signal pattern, a TCS response pattern, a signal pattern of a TCS filtered by a conventional Low-Pass-Filter (LPF) resulting in cascaded TCS response and Long Response (LR) pulse patterns with some overshoots. In the non-Xcor case as well as in the Cross-Correlated case a Peak Limiter (PL) or gradual Soft Limiter or Xcor Soft Limiter reduces the amplitude peaks. The LR filter extends the TCS response to multiple pulses and may introduce additional spectral saving, however could introduce additional ISI and increased peak variations. FIG. 6 shows a Cross-Correlated (Xcor) embodiment with Gaussian LPF and Integrator as well as sin and cos look-up tables. The TCS outputs of the I and Q baseband signals are further spectrally shaped and limited by sets of I and Q channel filters. A single or multiple cross- correlator (X), cos and/or sin inverter (XCSI) is used in this Agile Cascaded Mis-Matched (MM) (ACM) implementation. FIG. 7 illustrates NRZ signal and shaped Feher Return-to-zero (FRZ) signal patterns and an embodiment having TCS response and cascade LR filters in which the LR filter is implemented with digital IIR and/or FIR filters. FIG. 8 shows an analog BRA baseband implementation alternative of a TCS response processor for cross-correlated or not cross-correlated I and Q signals with selection or combined cascaded LR filter embodiment of this invention. FIG. 9 is a mixed analog and digital circuit implementation alternative of this cross- correlated TCS response processor in cascade with LR filters. FIG. 10 shows a BRA implementation alternative with a TCS processor, one or more D/A devices in cascade with a bank of switchable LR filters/processors and switchable Linearized Phase or Phase Linear (PL) and Not Linear Phase (NLP) Filters. FIG. 11 shows an FQAM implementation architecture diagram for multi-state Cross- Correlated FQPSK transmitters, also designated as FQAM. In this embodiment a single RF Amplifier operated in fully saturated NLA mode is used. FIG. 12 is an alternate implementation diagram of multi-state FQPSK, FGMSK and FQAM transmitters. In this embodiment two or more RF amplifiers operated in NLA saturated and/or in partly linearized (LIN) mode of operation are used FIG. 13 is an "Over the Air Combined" implementation architecture of FQAM signal generation having two or more quadrature FQPSK and/or FGMSK modulators, two or more RF amplifiers and two or more transmit antennas. FIG. 14 shows the embodiment of an Orthogonal Frequency Division Multiplexed (OFDM) embodiment with FDM signal combining of a number of FQPSK signals. In one of the embodiments of this invention RF Combining is implemented by hardware RF components while in an alternative implementation the RF combining is implemented "over the air". FIG. 15 shows a transmit Antenna Array and/or RF Combining implementation of multiple modulated signals. This figure illustrates multiple TCS response and/or cascaded TCS response and LR filtered cross-correlated baseband signal processors connected to an antenna array and/or RF combiner. FIG. 16 shows the Power Spectral Density (PSD) of NLA illustrative data links operated at 13Mb/s rate per link, in the US Government authorized band between 2200 MHz to 2290 MHz. With telemetry standardized filtered PCM/FM 3 links can be used simultaneously, with FQPSK-B the number of links is doubled to 6, while with NLA 16-state FQAM, also designated as a 2 nd generation multi-state FQPSK or FQPSK.2.4, the number of 13Mb/s links is quadrupled to 12 links (over that of standardized PCM/FM). FIG. 17 The PSD and Integrated Adjacent Channel Interference (ACI) of hardware measured prototype FQPSK-B in a NLA transmitter and of a BRA linearized transmit FQPSK is illustrated in the upper figure. In the lower part of this figure the Integrated ACI of FQPSK systems with that of GMSK (BTb=0.25) systems is compared. For NLA transmitters, the results show a very significant (approximately 2 to 1 ) RF spectral efficiency advantage of FQPSK over that of GMSK systems. The aforementioned FQPSK 2 to 1 spectral advantage over that of conventional GMSK is measured for a typical -60dB specification of the ACI. FIG. 18 Spectral results of 16 state NLA systems are illustrated. The ACI results FQAM, obtained after fully saturated NLA, are compared with that of NLA conventional pre-modulation filtered 16-state QAM systems. The spectral efficiency advantage of the NLA illustrated FQAM is more than 200% over that of NLA prior QAM. FIG. 19 shows BER performance curves, in terms of the customary BER = f(Eb/No) performance curves, of FQPSK Transceivers. Hardware measurements and/or computer design/software generated data and theoretical study results show that NLA practical RF hardware FQPSK Transceivers, with intentionally and substantially Mis-Matched(MM) filters are within about 0.5 dB to 1 dB of the ideal theoretical LIN amplified QPSK systems. FIG. 20 shows a demodulation architecture for FQPSK, FGMSK and FQAM and for other signals. FIG. 21 shows an alternate A/D converter based demodulator architecture. This implementation/embodiment is suitable for "software radio" demodulation and/or for firmware or hardware, or combined hybrid implementations of this invention . FIG. 22 shows transmit Antenna Arrays (AA) and receive Adaptive Antenna Arrays (AAA) in this multiple transmit and receive omni-directional and/or sectorized or high gain directional antenna- embodiment of this invention. This architecture has the potential to increases the NLA spectral efficiency of FQPSK, FGMSK and FQAM systems to more than 30 b/s/Hz.

FIG. 27 is a block diagram implementation of a two branch diversity receiver with an adaptive equalizer and a single demodulator. A NRED based circuit generates "smart" diversity selection and/or control signals.

Overview of Exemplary Embodiments Described A detailed disclosure of implementation architectures and embodiments of this invention is contained in the following sections. In many instances the text is related to the description of the respective figures and to the implementation of ACM transceivers. A changeable amount of cross-correlation between the BRA, CS, MFS and TCS response processor and/or combined or cascaded TCS and LR filters and/or post processor filters of the transmitter with selectable MM between the BRA transmitter and BRA receiver and CS processors, including single and separate in-phase (I) and quadrature (Q) signal storage/readout generators and single and/or separate I channel and Q channel D/A architectures for cross-correlated BRA, MFS and CS formats are also described. In agile cascaded mis-matched (ACM) designs for NLA and for Linearized (LIN) amplifiers selectable FQPSK filtering strategies, in the transmitter and separately in the receiver lead to further improvements in spectral efficiency. Within an interface unit (IU) 107 in FIG. 1 a generalized block diagram of an embodiment of this inventive Transceiver 100 is shown and includes a BRA 102, MFS, CS, MM filtered and RF frequency agile enhanced spectral efficiency, high performance Transceiver block diagram. In this embodiment one or more input signals 150-1 , 150-2, ..., 150-N are received on single or multiple lead(s) 101-1, 101-2 101-N and provided to a transmit section 152 of Interface Unit (IU) 102. The term lead or leads generally refers to a coupling or connection between the elements, and may for example refer to a wire, integrated circuit trace, printed circuit trace, or other signal link, connection, or coupling structure or means as are known in the art. Note that the IU provides an Interface port for transmission, designated as 102 and in the Receive section, also designated as 102, it contains the required IU receive processors and provides an output interface port. The input and output leads may contain and communicate analog or digitized voice, music, data, video, telemetry or other signals, or combinations thereof. In the FIG. 1 embodiment, signals 150 on input leads 101 may also represent Spread Spectrum, CDMA, WCDMA, CSMA, TDMA, FDMA or continuous single channel "Clear Mode", or other signals such as FDM and orthogonally frequency division multiplexed Orthogonally Frequency Division Multiplexed (OFDM) signals and IU port configurations. The BRA 102 unit, shown in FIG. 1 provides signals 153 to a Base-Band Processor (BBP) unit 103. This unit 103, receives in addition to the output signals from the IU 102, signals on lead 104 a Clock (C), on lead 105 one or more Control (CTL) signals and on lead 106 one or more Sampling (SAM) signals. The combination of the aforementioned C, CTL and SAM signals is also designated with a common further abbreviation as "C". BBP unit 103 provides a new class of BRA Cross-Correlated (CC) signals, including ACM filtered signals. The BBP provides signals to the Quadrature Modulator (QM) unit 109. Numerous embodiments of QM 109 have been described in the prior art and/or in the listed references. The QM implementation in baseband, IF and RF frequency ranges is well known by means of analog, digital and combined analog or digital techniques in hardware, firmware and in software and does not require further description. The Frequency Synthesizer, Unit 108, provides one or more unmodulated "Carrier Wave" signal(s) to the QM. The quadrature-modulated signals are provided to the Transmit Amplifier (AMP). The amplifier may be operated in a fully saturated mode, designated as Non-Linear Amplifier (NLA) or C-class amplifier or it may be operated in a Linearized (LIN or Lin) mode. Between the QM-109 and the Transmit AMP 111 part of the "RF Head" an optional combiner 110 is shown. Combiners 110 and/or post-AMP combiner 111 are optional units for Pilot Insert (PI) 1 and 2 designated as units 109 and 112, respectively. The RF head's transmit AMP is connected to Switch (SW) and/or Combiner/Splitter device 113 and this 113 unit provides the signal for transmission to and from antenna 114. Instead of the aforementioned antenna a separate port could be used for signal transmission or reception of "wired" systems. The Pilot Insert (PI) optional units may provide in band/or out of band pilot tones for transmission. These tones could be used for fast and robust performance receiver demodulators and synchronizers. In the transmit and receive sections Switch 113 or Switch or Combiner or Diplexer is connected to the receive Band Pass Filter (BPF) 115. Instead of Switch 113 a Combiner/Splitter could be used. The received signal after the BPF is connected to a Low Noise Amplifier (LNA) unit 116. The optional down-converter unit 117 receives its inputs from the Frequency Synthesizer and from the LNA and provides it to band-pass filter (BPF) 118 for further processing. The entire down-conversion stage of the receiver, including the receive section of the Frequency Synthesizer, mixers 117 and 118 are deleted for the so-called Direct Down-Conversion type of receivers. The quadrature demodulator (Quad Demod) may contain components such as Automatic Gain Control (AGC), Frequency Tracking, Synchronization and Post Demodulation, Signal Conditioning including Symbol Timing Recovery (STR) circuits. The demodulated signal provided by demodulator unit 119 is fed to the receive section of the IU 102. The receiver section of the IU 102 contains on lead 101 the output signal and output port. Description of an Exemplary Embodiment of a FQPSK Bit Rate Agile Transceiver In this part of the detailed description of the invention the focus is on Quadrature Modulated (QM) four (4) state FQPSK systems. These four state systems have in general, in the sampling instants, in the I and Q baseband channels 2 signaling states (for short "states"). In the baseband I channel and in the baseband Q channel there are 2 signal states. The architectures and embodiments of nine (9) state FQPSK systems are essentially the same as that of 4 state FQPSK Transceivers. An exception is that the baseband I and Q Cross-Correlated and BRA signal processors provide 3 level (state) baseband I and Q signals and results in 3x3=9 state modulated FQPSK systems. Most implementations and embodiments and alternatives apply to multi-state (more than 4 state) Quadrature Modulated systems, described in later sections, such 9, 16 or 64 or 256 state QM systems having 3, 4, 7, 8 and 16 states in their respective baseband channels. In FIG. 2 on lead 6.3 a serial data stream is present. This signal is provided to 6.4a and the optional 6.4b units for Serial-to-Parallel (S/P) conversion and a 1 bit duration (Tb) offset in one of the implementations. In other implementations there is no offset delay 6.4b in the embodiment. Some other alternate embodiments use a selectable offset delay 6.4b which is larger or equal to zero and smaller than the duration of approximately 200 bits. As stated the Offset logic is used in certain embodiments, while in other architectures it is not present. The input signal or input signals are provided on leads 6.1 and 6.2 instead of lead 6.3 in some of the alternative implementations of this invention. Unit 6.5 is a Base-Band Processor. Unit 6.5 may be clocked, controlled and sampled by signals such as C, CTL, and SAMP such as illustrated previously in FIG. 1. In this figure, FIG. 2, all of these clocking, control and sampling signals which could represent multiple rates and multiple leads are collectively or individually abbreviated simply as "C" and illustrated with an arrow near the letter "C." Unit 6.5 in some of the embodiments performs the Time Constrained Signal (TCS) processing, waveform assembly and generation functions of multiple symbol TCS cross correlation and signal processing operations. The I and Q outputs of unit 6.5 are provided as inputs to the transmit set of LPFs designated as TX1 LPF-1 unit 6.6 and TXQ LPF-1 unit 6.11. This set of first LPFs could be cascaded with a second set of I and Q channel LPFs units 6.7 and 6.13. Switch units 6.8 and 6.12 illustrate that the second set of LPFs could be bypassed and/or deleted in some of the embodiments. The LR filter units, embodied by the first and second sets of I and Q are implemented as LPFs or alternately as of other types of filters such as Band-Pass Filters (BPF) or High Pass Filters (HPF) or other filter/processor LR filter combinations. As stated previously, for several embodiments all of the aforementioned processors are BRA and ACM, while for other implementations bit rate agility and/or ACM may not be required. Units 6.9, 6.10, 6.14, 6.15 and 6.16 comprise a quadrature modulator in which the I and Q modulators are 90-degree phase shifted and in which a Local Oscillator (LO) is used as a Carrier Wave (CW) generator. Unit 6.17 is an amplifier that could be operated in a LIN or in a NLA mode. The output of amplifier 6.17 is provided on lead 6.18 to the transmission medium. In FIG. 2 at the receiving end, on lead 6.19, is the received modulated signal. Unit 6.21 is a BPF that is present in some embodiments while in others it is not required. Alternatively the receive BPF could be "switched-in" or "switched-out" by switch 6.20. In some implementations Surface Acoustic Wave (SAW) BBF were used to implement 6.21. Units 6.22, 6.23, 6.24 and 6.25 embody a Quadrature Demodulator (QD) with a corresponding Local Oscillator (LO). The aforementioned LO represents for some embodiments an entire Carrier Recovery (CR) subsystem while for other embodiments it is a free running LO. The set of LPFs 6.26 and 6.27 are the embodiment of post-demodulation filters, while the second set of LPFs 6.28 and 6.29 may be used to further enhance the spectral efficiency advantages or other performance advantages of designed ACM systems. The second set of LPFs could be connected or disconnected by switches 6.30 and 6.31 or entirely deleted. Unit 6.32 is the Clock Recovery (CR) and/or Symbol Timing Recovery (STR) system. For fast clock and/or STR, this unit is connected in some of the embodiments in parallel to the Carrier Recovery (CR) subsystem. In one of the embodiments of fast Clock Recovery (CR) systems, the parallel configuration embodied by units 6.37 and 6.38 is used for discrete signal clock generation. The discrete signal spike, in the frequency domain, provides on lead 6.39 the clock recovery unit 6.32 with a discrete spectral line signal which is exactly at the symbol rate or at the bit rate. In this architecture unit 6.37 is a multiplier or any other nonlinear device which has at its input the received modulated signal and the same received modulated signal multiplied by a delayed replica of itself. The aforementioned delayed replica is generated by unit 6.38, a delay element. The receiver structure, shown in FIG. 2, is one of the many possible alternative receiver and demodulator structures. It is inter-operable compatible and suitable for BRA and MFS and CS reception, demodulation and/or decoding of the transmitted signals embodied by means of the BRA and/or MFS and/or CS and/or ACM implementation of the FIG. 2 transmitter embodiments. Contrary to the teachings and wisdom of well established bandwidth efficient communication theory, of matched filter-optimal demodulation theory and optimal data reception theories, in several embodiments of the current invention, substantially Mis-Matched (MM) modulator and the demodulator filters have been implemented. Fundamental and pioneering discoveries, regarding the cascaded pulse response of TCS response and of LR filter cross- correlated BRA implementations of modulator I and Q filters and that of the implementations of "matched " and/or intentionally " Mis-Matched" (MM) demodulator filters are disclosed in this part of the invention. In classical communication theory the demodulation LPFs, and in fact the entire cascaded receiver and demodulation filter responses are matched to the characteristics of the modulator and entire cascaded modulator and RF transmitter filters. Minimum bandwidth-maximal spectral efficiency, optimal performance requires that the Nyquist minimum bandwidth theorems be satisfied for ISI free and matched signal transmission/reception. The intentionally and substantially Mis-Matched (MM) transmit and receive filter designs, used in implementations of this invention lead to simpler implementations than implied by communication matched filter theory and by Nyquist minimum bandwidth theories and to substantially improved performance for RF power efficient NLA transceivers. From communications theory, numerous books, referenced publications as well as from patents it is well known that for "optimum" performance the cascaded filters of the modulator should be matched by the cascaded receive demodulator filters. For example, in a conventional bandlimited QPSK system, if Nyquist filters are implemented as "raised cosine filters", then the best "optimal" performance is attained if the cascaded transmit and receive filters have a raised cosine transfer function and the filtering is equally split, i.e. "matched " between the transmitter and receiver. For pulse transmission, such as filtered NRZ data an aperture equalizer, having an wTs/ sin(wTs) frequency response is used in theoretical optimal transmitters, prior to the implementation of the transmit matched filter. Specifically, based on Nyquist transmission and filter theories, combined with matched filter receiver theories the 3dB cut-off frequency of an optimal minimum bandwidth transmit filter, used as a baseband I or Q channel filter, in a QPSK system equals 1 / 2 of the symbol rate or alternatively % of the bit rate. The 3dB bandwidths of the modulator and demodulator filters of the "theoretical optimal" bandlimited QPSK system are matched. The 3dB bandwidth of the theoretical optimal system it is the same for the modulator filter and for the demodulator filter. If these filters are implemented by pre- modulation LPFs and post-demodulation LPFs then the aforementioned theoretical bandwidth corresponds to BTs=0.5. This value corresponds to BTb=0.25, where B is the 3dB bandwidth of the respective filters, Ts is the unit symbol duration and Tb is the unit bit duration. Contrary to the teachings of the aforementioned optimal performance matched filter modulation demodulation theory, we disclose the implementation of demodulator architectures and embodiments with "Mis-Matched" (MM) filtering, and specifically for agile (bit rate) cascaded mismatched (ACM) implementations. The term Mis-Match (MM) refers to intentional and substantial MM between the cascaded 3dB bandwidth of the I and Q demodulator filters and/or to the MM with respect to the Nyquist theory stipulated bandwidth, with that of the cascaded response of the modulator I and Q filters. Alternate embodiments include MM pre-modulation baseband LPF and post-demodulation baseband LPF designs as well as post modulation BPF transmitter implementations and receiver pre-demodulation BPF implementations. A combination of the aforementioned baseband and BPF designs has been also implemented. The term "substantial" MM in a BRA architectures and embodiments such as shown in the alternate implementation diagrams in FIG. 2 implies typically more than about 30% mis-match between the respective 3 dB cut-off frequencies of the transmit and receive filters, but this value is exemplary and is not a limiting amount of mis-match. The I and Q baseband signal patterns are generated with several structures and elements, described as parts of this invention. The aforementioned TCS signal patterns are available at the outputs of the following elements: in FIG. 2 at the output leads of TCS 6.5, in FIG. 3 at the output leads of D/A Units 7.8 and 7.11. In FIG. 4 at the output leads of units 8.7 and 8.8. In FIG. 3 one of the alternate implementations of Bit Rate Agile (BRA) transmitters is shown. The illustrated embodiment of the current invention uses a variation and alternative implementations of the "Basic Cross-Correlator" (XCor) and post cross-correlation processors, as disclosed in prior patents of Feher et al., with several original embodiments described in conjunction with FIG. 3. In cascade with the basic Xcor which implements TCS response processed cross-correlated or TCS not-cross-correlated signals is a second set of LR filtered processors. In cascade with the 2 nd processor and with Digital to Analog (D/A) converters are pulse shaping bit rate agile LR filters, implemented as Low-Pass-Filters (LPF) or other type of filters in the I and Q channels. As stated previously, BPFs, HPFs or other types of processors/filters could replace the LPFs. On lead 7.1 is the input signal to unit 7.2, which implements S/P, DE and Gray encoding and/or other logic functions. Logic 7.3 is a cross correlator that is used to cross correlate I and Q signals. The duration of the cross correlation processor and implementation of the basic Xcor is selectable in the current invention. It is selectable in a wide range, from zero, i.e. no cross-correlation to a fraction of a bit interval, and is adjustable and/or selectable up to many bits and/or symbols. In some of the alternate implementations of FIG. 3 the entire cross-correlation Unit 7.3 designated as "Logic" is not used, that is, it is deleted from FIG. 3, in the generation and assembly of the TCS response signals, provided by the signal generator set 7.4. In logic/cross-correlator 7.3 six symbol shift registers are shown for the I and Q channels. As stated in alternative embodiments the cross correlation is deleted. The basic signaling elements, also referred to as wavelets, designated F1 , F2, ..., F16 are generated and/or stored by a set of signal generators or storage devices designated as 7.4. The aforementioned storage units or wavelet generators are implemented in one of the alternate embodiments with ROM and/or RAM chip sets and/or are part of a firmware and/or software program. In certain embodiments a fairly large number of wavelets are generated, i.e., a set of SO, S1 , S2 S63 or even more wavelets are generated, while in other embodiments only 2 or 4 signaling elements (wavelets) are used. In alternate implementations instead of generating and/or storing separate and distinct signals or "wavelets", a very small number of wavelets is stored and their inversions in terms of amplitude inversion and time inversions are used. In the embodiments of the current invention the elements are suitable for BRA and ACM operation. Units 7.5 and 7.6 are designated as two multiplexes and are embodied in some implementations as a single integrated multiplexer unit or more than one unit. In one of the embodiments all digital processors, including units 7.2 to 7.16 are implemented as a single function and unit. Unit 7.7 is a second processor and provides for optional additional cross correlation and amplitude limiting, also designated as signal clipping or Peak Limiter(PL). PL are implemented by clipping devices and/or other commercially available prior art nonlinear devices. Other conventional devices described previously in these specifications as well as in the prior art literature embody units 7.8 to 7.13. Amplifier 7.15 provides the RF modulated signal to the antenna 7.17 through a switch and/or combiner or splitter 7.16. In FIG. 4 a Quadrature Modulated (QM) Transceiver embodiment of this invention is shown. On lead 8.1 the input signal is provided to the optional S/P and/or DE and/or Logic/Coding processor 8.2a. Unit 8.2b is an optional (Opt.) Xcor, designated in FIG. 4 as Xcor 1. Unit 8.2b provides I and Q signals through the optional offset delay, D1 unit 8.3 or optional bypass switch 8.4 for further processing to units 8.5 and 8.6. Units 8.5 and 8.6 implement one or more I and Q processing operations of Intersymbol lnterference(ISI) and Jitter Free (IJF) signals such as cross- correlated amplitude-adjusted IJF signals or other TCS cross-correlated and/or non-cross- correlated signals including binary and multilevel SQAM signaling elements in cascade with LR filter subsystems such as IIR and/or FIR processors which are operated in a BRA mode. Units 8.7 and 8.8 are D/A optional single shared D/A, or multiple D/A converters that provide signals to the second set of filters 8.9 and 8.10. Analog, digital or hybrid hardware, software or firmware in unit 8.11 implements an optional cross correlator. The I and Q output signals of 8.11 are provided as baseband drive signals of the QM 8.12. Local Oscillator (LO) 8.13 provides the RF unmodulated CW to the QM. The QM provides to Amplifier 8.14 a signal for amplification to antenna 8.15 or to the transmission medium. One of the embodiments has a very simple/efficient implementation of the TCS response cross correlated transmit (Tx) processor with only 4 samples/symbol and only three(3) wavelets. In FIG. 5 Peak Limited (PL) and other TCS response signal patterns of this invention as well as that generated by the prior art Superposed Quadrature Modulated Baseband Signal Processor ("SQAM") Seo/Feher's U.S. Patent 4,644,565, Ref. [P4] are illustrated. Signal pattern designated as 9.11 is a conventional prior art NRZ signal, while TCS pattern 9.12, if it is not cross- correlated with an other signal or not cascaded with a LR processor, represents a processed prior art SQAM generated baseband signal wavelet pattern. If the TCS pattern 9.12 signal is connected to BRA one or more filters, including LR filters and/or ACM Processor's and it is part of I and Q cross-correlated signal generators and BRA processors, then it is a new implementation of this invention, having a substantially enhanced bandwidth efficient signal. Signal pattern 9.12 is reproduced as signal pattern 9.13. The dotted line of signal pattern. 9.14 illustrates the TCS processor and cascaded Long Response (LR) filtered output sample signal pattern. The 9.14 LR filtered signal pattern is more spectrally efficient than the 9.12 TCS response signal, however it may contain more Intersymbol-lnterference (ISI), more Data Transition Jitter (for short "Jitter") and higher signal peaks than the TCS signal pattern. A PL or "Clipped" signal pattern 9.16 of this invention is illustrated with dotted lines adjacent to signal pattern 9.15. Signal clipping and/or smooth gradual or soft PL or abrupt peak limiting of TCS, and/or of TCS response processors cascaded with LR filters and/or cross-correlated signals reduces the overall signal excursion of the peak to peak amplitude variation of the I and Q signals. It also reduces the envelope fluctuation of the I and Q modulated signal. Applications include I and Q analog and digital signals, including Orthogonal Frequency Division Multiplexed (OFDM), clear mode non-spread spectrum as well as spread spectrum signals, such as CDMA and also TDM or TDMA, CSMA and FDMA architectures. A Cross-Correlated (Xcor) embodiment of this invention for a BRA architecture, and also suitable for ACM operation, is shown in FIG.6. It is suitable for several classes of FQPSK, FMOD, FGMSK, FMSK, FGFSK and FQAM implementations. The implementation includes Gaussian LPF and Integrator and/or other filter processor as well as sin and cos look-up and/or other " look up tables". BRA implementations and implementation of TCS and LR filtered/processed Cross- Correlated (CC) baseband I and Q signals and the corresponding Quadrature Modulator (QM) and RF amplifier (Amp) are included in the embodiment of FIG. 6. The aforementioned term "look up tables" refers to TCS response wavelet storage and/or wavelet generation units. In alternate embodiments the sin and cos wavelet generators and/or wavelet storage and readout units are replaced with other wavelets than the aforementioned sin and cos function generated wavelets. On lead 10a.1 an input analog, digital or mixed signal is provided to Unit 10a.2 also designated as Filter 1. This filter as well as other components of the transmitter are Clocked/Controlled and/or Sampled by one or more 10a.3 signals, designated for short by the letter C. Filter 1 , 10a.2 is a Gaussian shaped, Butterworth, Bessel or other filter or combination of filters and processors and it is configured in LPF, BPF or HPF mode. Unit 10a.4 is a second signal processor. It embodies an Integrator or some TCS signal shaping units and/or LR filter ACM implementation. Splitter 10a.5 splits or converts such as with a serial-to-parallel converter, the signal into I and Q signals. The I and Q signals provided by the 10a.5 splitter output are further spectrally shaped and limited by the set of I and Q channel LPF's, designated as Filt 21 and Filt 2Q. These optional (Opt.) F2l and F2Q Bit Rate Agile Filter(BRA) elements 10a.6 and 10a.7 in FIG. 6 are TCS and/or Long Response(LR) filters, where the term "Long Response" refers to the typically longer pulse and/or impulse response of the LR filters than that of the TCS filters. This cascaded TCS and conventional filter approach is applicable for bit rate agile spectrum enhanced GMSK signal generations, also designated as FGMSK containing elements related to U.S. Pat. 5,789,402 (for short '402); however, with the new single or multiple ACM Cross-Correlated (X) Single or Multiple Cos (C) and Sin (S) and/or Inverter (I) (for short "XCSI" and/or Peak Limiter (PL) processor components of this new invention. The second optional (Opt.) filter set is 10a.6 and 10a.7. This set provides for processing of the I and Q signals provided by 10a.5. The XCSI unit 10a.8 cross-correlates the aforementioned I and Q signals with a C driven clock/sample/control and provides for selectable amount of cross-correlation between the I and Q channels, including for a cross-correlation reduced to zero, i.e. no cross-correlation between the TCS and LR processed signals. In some of alternate embodiments of this invention there is no cross-correlation apparatus used. In units 10a.9l and 10a.9Q optional additional filtering processing is implemented by optional units F3I and F3Q. These units provide optional ACM filtered/processed BRA cross-correlated or not-cross- correlated I and Q signals to the Quadrature Modulator unit 10a.10 which in turn provides the signal of amplification to Amplifier (Amp) 10a.11 and to output port 10a.12 for signal transmission or broadcasting. The output port is represented by connector 10a.12. In FIG. 7, a conventional Non-Return to Zero (NRZ) signal pattern is illustrated in 11a.1. In 11a.2 a modified Return to Zero (RZ) pattern designated as Feher Return to Zero (FRZ) data pattern is shown. Both of the NRZ and FRZ signals are Time Constrained Signals (TCS). The FRZ signal 11 a.2 has an adjustable amount of Delay (D) for the forced transition instance from the logic state 1 to logic state 0. The FRZ signal is used in some of the TCS embodiments, 11a.3 while in other TCS architectures FRZ is not in use. One of the advantages of FRZ signals is that they may contain discrete spectral lines and have a more robust performance in RF time dispersive or frequency selective faded systems if used in conjunction with modulators/demodulators, including but not limited to quadrature modems. The FRZ signal contains, in some embodiments, non-symmetrical or asymmetrical rise and fall times and even pulse shapes. The TCS unit 11a.3 has as its inputs one or more signals as well as the "C" signals where C designates optional clocks, and/or sampling including over- and/or under-sampling signals and/or other control signals. The TCS processor in one of the embodiments generates Non-Cross-Correlated (NCC) signals while in another embodiment Cross-Correlated (CC) signals are generated in unit 11a.3. In the case of digital processing such as FPGA and/or ROM and/or RAM, digital implementations D/A converter(s) 11a.4 are provided. In one of the embodiments a single D/A is implemented. The single D/A is providing time shared or time multiplexed signals as I and Q inputs for Quadrature Modulation (QM). Prior to QM an optional analog processor and/or filter with possible BRA clocked operation, 11a.5, is implemented. The QM 11a.6 provides BRA quadrature modulated signals to optional amplifier or cascaded amplifiers 11a.7 which could operate in a linear mode or partly linearized mode or in a fully saturated NLA power efficient mode. The aforementioned amplifier provides the signal to the Antenna 11a.8 or alternatively to the output port 11a.9 for signal transmission. In FIG. 8 another analog BaseBand (BB) embodiment using predominantly analog components is illustrated. Units 12b.1 to 12b.5 are signal sources such as previously described. Unit 12b.6 is a previously described clock/ sample/controlled source abbreviated with the letter C. Unit 12b.7 provides selection and/or combinations and permutations of the signal sources with amplitude adjustments of the aforementioned signal sources which operate at the same rate in some embodiments and operate in asynchronous non-related bit rates to each other in other embodiments. Unit 12b.7 provides one or more signals to standard and readily available components such as 12b.8 to 12b.24. These components provide inputs to the "select" or "combine" unit 12b.25 which has at its input optional Control (CTL), Clock Bit Rate (CBR) and Control Sampling Time (CST) signals. One or more of these signals, by itself or in combination, may constitute multiple inputs and are synonymously further abbreviated and designated as "C" in several parts of this invention. Units 12b.26 and 12b.27 provide further signal processing for the outputs of 12b.25 and generate I and Q output signals. ln the embodiment of FIG. 9 an implementation comprising mixed analog and digital circuit components is shown. On lead 13a.1 the data input or DIN provides two 13a.2 signals for multiplexing control/logic processing and memory. In one of the embodiments, logic processing and memory storage/processing converts the input signal to a Trellis Coded (TC) baseband signal. Control signals present on leads 13a:3 serve as one of the inputs to the N by M (N x M) channel multiplexer and cross correlator and/or other TCS unit 13a.6. Analog inputs of 13a.6 could be generated by unit 13a.4 and further processed by analog components such as the set of components 13a.5 of this particular embodiment. Units 13a.7 and 13a.8 provide additional digital timing bit rate and sample clock scaling, n/m rate division and miscellaneous logic functions embodied by standard logic gates and/or DSP and/or Analog Signal Processing (ASP) components. FIG. 10 shows an alternate design of the current invention including a bank of switchable filters/processors with Linearized Phase or Phase Linear (PL) and Not Linear Phase (NLP) Filters. Phase Linearization Components may be entirely deleted or, if included in this implementation, they may be switched in and out in this hybrid analog and digital transmit implementation of the transmitter. Unit 14.1 is the embodiment of a TCS processor for time constrained signals with or without cross correlation implemented for FQPSK or FGMSK or FQAM or FMSK or related BRA signals. The output(s) of the 14.1 TCS processor provides one or more signals to the optional D/A unit 14.2. The outputs of the single or multiple D/A or of 14.1, in case 14.2 is not used, are provided to the cascaded I and Q filters and Switches 14.3 to 14.5. While the filters are indicated as LPF-1 to LPF-3, they have been implemented as low-pass, band-pass and high-pass filters providing the LR pulse response with or without phase equalization. These filters may be designed for Agile Cascaded Mis-Matched (ACM) systems. An alternate embodiment comprises TCS unit 14.6 connected through optional D/A unit(s) 14.7 to the bank of 14.8, 14.9 and 14.10 selectable or combined switched phase equalized or non-phase equalized parallel and/or cascaded units LPF-11, LPF-1Q to LPF-M1 and LPF-MQ filters. On output ports 14.11 and 14.12 the processed I and Q signals of the aforementioned particular embodiment of this invention are available for further processing. Description of Multi-State FQPSK, FQAM, FGMSK and FMSK In this section of the detailed description of this invention the focus is on Quadrature Modulated (QM) multiple signaling state (for short "state") systems with more than 4 signaling states of the QM signal and more than 2 states in the respective I and Q baseband channels. In the previous section the focus was on the description of QM four (4) state FQPSK systems. These four-state systems have, in general, in the I and Q baseband channels 2 signaling states (for short "states") in the I channel and 2 states in the Q channel. Most implementations and embodiments of the 4-state systems apply to multi-state (more than 4-state) Quadrature Modulated systems, described in this Section, such as 9, 16, 49 or 64 or 256 state QM systems having 3, 4, 7, 8 and 16 states in their respective baseband channels. The technologies and embodiments described for the multiple state systems are also applicable for the implementations and embodiments of 4-state systems. Forward and Backward COMPATIBILITY and/or interoperability between the 4-state and, more than four-state, multiple state FQPSK and Feher's Quadrature Amplitude Modulation (FQAM) and multi-state FGMSK and FQPSK systems is a definitive advantage in new product developments. Additionally some of these systems are also backward compatible with the previously patented Feher BPSK (for short FBPSK and FMOD) systems, such as disclosed in [P1] and [P2] and the references in the aforementioned U.S. Patents and cited references. A multi-state QM architecture for 4 or more than 4 states, designated as FQAM is illustrated in the embodiment of FIG. 11. In this implementation block diagram of an FQAM multi- state Cross-Correlated BRA Transmitter a single RF Amplifier operated in fully saturated NLA mode or Linearized (Lin) mode of operation is used. The Input Signal is connected to an optional Encoder unit 20.1. This unit, if used includes logic processing and Encoding functions such as Trellis Coding or CRC or FEC or DE or Gray Coding, Serial to Parallel conversion and/or other digital processing functions. In one of the embodiments an optional S/P (Serial to Parallel) converter, unit 20.2 is included to process the signals received from 20.1. The Signal Mapper 20.3 maps the binary signals from 2 states to M states (levels) and includes in some of the embodiments Cross-Correlation between the binary and/or between the converted multi-state signals. The outputs of the Signal Mapper TCS unit 20.3 are connected to D/A converters 20.4 and 20.5. The D/A Cross-Correlated BRA signals are TCS multilevel Cross-Correlated signals with variable and/or presetteable Xcor. In alternate embodiments no cross-correlation between the I and Q signals is implemented. The D/A outputs are fed to 20.6 and 20.7 filters, indicated in the drawing as LPF. These filters are LR filters and are implemented with MR digital or IIR analog filters or a combination of conventional analog or digital filters. The BRA signals, which have been Cross-Correlated and are TCS in cascade with LR signals are provide to the inputs of Quadrature Modulator(QM) 20.8. The QM has an unmodulated Carrier Wave input from unit 20.9. The Quadrature Modulated signal is processed by an optional "Roofing Filter" to remove higher order spurious components and is fed to amplifier 20.12 and to antenna 20.13 or output port 20.14. An optional Pilot Tone or Multiple Pilots are added to the RF signal by Pilot Generator/adder 20.11. Combining adding of pilot signals is achieved by hardware combiners or by adding Unmodulated signals over the air through a separate antenna. A 16 state FQAM embodiment is illustrated in the implementation architecture and block diagram of FIG. 12. This architecture can be extended and/or modified to 64 state or to other larger or smaller number of signaling states. In simple terms NLA Quadrature Modulated systems are generated by FQPSK or FGMSK or FMSK type of 4 state QM embodiments (for short the generic term "FQPSK' is also used) as described in earlier sections of this invention. If two NLA four state RF signals are combined than a 16 state NLA signal is obtained. If three NLA four state RF signals are combined than 64 state NLA signal is obtained.. If four NLA four state RF signals are combined than a 256 state NLA signal is obtained and the number of signal states can be further increased by the aforementioned extension of the multiple signal combining process. The term "combining" or "Combiner" or RF signal addition in FIG. 12 is accomplished by an RF hardware combiner. Off the shelf, readily available components, such as Hybrid Microwave Combiners, are suitable for hardware RF combining. On lead 21.1 in FIG. 12 an input NRZ data signal is provided to the input ports of the Serial/Parallel(S/P) Converter 21.2. Four parallel data signals, designated as 11 , Q1 and 12, Q2 are provided to FQPSK (or FGMSK or FMSK) modulators 21.3 and 21.4. One of the embodiments and/or implementations of FQPSK previously disclosed in the detailed description of this invention implements 21.3 and 21.4. The FQPSK signals are provided to Optional (Opt) preamplifiers, which operate in Linearized(LIN) or NLA mode. The High Power Amplifiers (HPA) 21.7 and 21.8 provide the RF amplified modulated signals to RF Combiner 21.9, which in turn provides the NLA combined 16-state signal to the output port 21.10. In Seo/Feher [9] and [P4] and [6; 8] prior art references, implementation architectures of NLA systems operated in 16-QAM, 64-QAM, 9-QPRS, 81-QPRS and other quadrature modulated systems have been described and/or referenced. The aforementioned prior art does not include NLA cross-correlated, filtered and bit rate agile NLA systems for QAM disclosed in this invention, and in particular related to the discussion of FIG. 12 and FIG. 13. Based on these Feher et al. references, one of the embodiments, is related to the architectures of FIG. 12. To obtain a 16- state QAM with cross-correlated FQPSK signals that are NLA through HPA1 and HPA2, the RF amplifiers and RF combiner are adjusted to have an RF combined output fed to RF combiner, unit 21.9, which provides the RF combined output 21.10. The RF combined output power generated by unit 21.7 - HPA1 is 6dB higher than the RF power provided to output 21.10 by HPA2 designated as unit 21.8. FIG. 13 is the implementation architecture of "Over the Air Combined" FQAM signal generation by implementing 2 or more FQPSK and/or FGMSK type of signals. In FIG. 13 instead of the use of a hardware embodied RF Combiner to combine the HPA1 and HPA2 signals, the output signals of HPA1 and HPA2 are fed to two separate antennas and transmitted as wireless signals "over the air." In this architecture RF Combining is achieved "Over the Air" that is the RF signals are transmitted over a wireless medium and combined in the receiver antenna. The baseband processor, quadrature modulator and signal amplifiers architecture of the NLA signals, "Over-the-Air Combined," is closely related to that of FIG. 12 which uses the hardware RF combiner. The input NRZ data on lead 22.1 is provided to a Serial/Parallel (S/P) unit 22.2 which provides 4 parallel signals two FQPSK quadrature modulators, units 22.3 and 22.4. The quadrature modulated signals are provided to amplifiers, and in particular, to optional NLA 22.5 and to High Power Amplifier (HPA) 22.7 in the upper part of the figure. HPA-1 , unit 22.7 provides the RF modulated signal to antenna 22.9 or to an output port 22.11. In the lower branch the FQPSK modulator, unit 22.4, provides the quadrature modulated signal to optional NLA 22.6 and to HPA-2, unit 22.8. The amplified signal of 22.8 is provided to antenna 22.10 and/or to output port 22.12. To obtain a 16-state QAM with cross-correlated FQPSK signals that are NLA through HPA-1 and HPA-2, the RF amplifiers and RF combiner are adjusted to have an RF combined output fed to antenna 22.9 and/or output port 22.11 , 6dB higher in power than the RF power provided to antenna 22.10 and/or output port 22.12. FIG. 14 shows the embodiment of an Orthogonal Frequency Division Multiplex (OFDM) type of embodiment with FDM signal combining of a number of FQPSK type of Lin or NLA signals. In one of the embodiments of this invention RF Combining is implemented by hardware RF components while in an alternative implementation the RF combining is implemented with "Over the Air Combined" signals. If multiple antennas are used, then this architecture is also known as an "Antenna Array" (AA) architecture. Lead 23.1 containing the Input Data (ID) is provided to a Serial-to-Parallel (S/P) converter, unit 23.2, having M set of outputs where one output set constitutes a separate I and Q signal or a serial data stream. The S/P converter 23.2 may contain an optional cross correlator (Xcor). As the input signal is S/P converted, the data rates on the 1 , 2 M input leads to the bank of FQPSK modulators 23.3 are at an M times reduced data rate compared to the input data rate. As an illustrative example of this architecture, if the input data rate is Fb=1 OMb/s and there are 100 FQPSK modulators (M=100), then the bit rate of individual FQPSK modulators is 10Mb/s: 100=100 kb/s. The aggregate transmission rate of such a system is not changed. The aforementioned parallel data are provided to M modulators designated as FQPSK.1 , FQPSK.2, ..., FQPSK.M, collectively referred to as unit 23.3. These modulated signals are provided to a set of RF amplifiers, 23.4 and optional RF Switches units designated as 23.6. The M amplified signals are provided in one of the embodiments through RF combiner 23.7 to a single antenna "Ant.C" unit 23.8 or port 23.9. In an alternate use the M modulated and amplified signals at the outputs of RF amplifiers 23.4 are provided to the antenna array 23.5 designated as Ant.1 , Ant.2 to Ant.M. If the Antenna Array architecture is used, then the M signals are "Over the Air Combined" signals. If a hardware RF combiner 23.7 is used with a single antenna 23.8 or output port, then the architecture represents a hardware combined embodiment. An advantage of the "Over the Air Combined" architecture is that all RF amplifiers within the set 23.4 may operate in fully saturated NLA power efficient mode. FIG. 15 is an alternate Antenna Array and RF Combining implementation architecture of multiple FQPSK type of signals. This figure illustrates multiple TCS and/or filtered BB processors connected to an antenna array and/or RF combiner. Input lead 24.1 contains an input signal or a multitude of signals, which could comprise analog signals, digital binary or digital multilevel signals, or other signals, for short "Input Signal." Unit 24.2 receives the input signal and processes it with a TCS containing optional LR filters and/or a 1 st set of cross correlators (Xcor) for FQPSK signals. A Bit Rate Agile clocked bank of filters 24.3 receives the signals of 24.2, processes them and provides to unit 24.4 which is an optional 2 nd set of Xcor and/or TCS with LR response filters and/or Peak Limiter (PL) devices. The signals from 24.4 are provided to Quadrature Modulators 24.5 and to a bank of amplifiers 24.6 in the figure illustrated as FA1 to FA3. The RF amplified signals are provided to antenna array 24.8 or to RF combiner 24.9 through the set of RF switches 24.7. The RF combined output is provided to antenna 24.10 or alternately output port 24.11. Illustrative Performance of Exemplary System The performance of illustrative and some of the "best-illustrative" embodied FQPSK and related BRA systems of this invention is highlighted. This invention includes numerous embodiments and has a large class of subsystems and implementation details as well as designations. For this reason the term "best-illustrative" is used herein. For some users and designers "best" means the narrowest possible spectrum at a Power Spectral Density (PSD) of about -20dB to meet certain FCC mandated requirements, while for other users the "best" PSD is defined at -70dB for others "besf refers to best Bit Error Rate (BER) performance in an Additive Wide Gaussian Noise (AWGN) operated environment, while for some others the "best" or "optimum" BER=f(Eb/No) performance is most desired. Other categories of the term "best" could mean fastest synchronization or re-synchronization of a receiver/ demodulator or "best" BER performance or smallest number of outages in an RF delay spread-frequency selective faded environment with the "best," that is, fastest and highest performance adaptively equalized demodulators. A large category of designers and users of this invention might define "besf as the lowest cost commercially available equipment from numerous sources having the highest spectral efficiency simultaneously with the smallest size for a certain RF power and the "best," i.e., maximal Bit Rate Agile (BRA) flexibility and/or interoperability and compatibility with previous generations and implementations of FQPSK and/or of other "legacy" systems. For the aforementioned reasons the term "best illustrative" is used in the performance attained with some of the aforementioned "best" implementations. As an illustration of one of the "best illustrative" NLA spectra, the Power Spectral Density (PSD) of NLA wireless/telemetry system is illustrated in FIG. 16. The multiple data links in these telemetry systems are operated at specific bit rates of 13Mb/s rate per link. The spectra shown in FIG. 16 are typical for spectral usage in the U.S. for the U.S. Government-authorized band of 2200 MHz to 2290 MHz for Government applications. In FIG. 16 one or more of the modulated and received signals is shown to be in the 18dB to20dB lower than that of adjacent signals. In "real-life" systems it is often the case that the desired signal power is about 20dB lower in power than that of the adjacent signals. With telemetry standardized filtered PCM/FM systems, at the aforementioned 13 Mb/s rate, 3 data links can be used simultaneously. During the 1990s, filtered PCM/FM systems have been extensively used. With emerging FQPSK systems and in particular Draft Standardized FQPSK-B systems the number 13Mb/s rate links is doubled to 6, while with 16-state FQAM, also designated as FQPSK.2.4 the number of 13Mb/s links is quadrupled (over that of standardized PCM/FM) to 12 data links. Thus the spectral efficiency of FQPSK is double that of standardized filtered PCM/FM and the spectral efficiency of FQAM with 16 states and operated also in an NLA mode is quadruple that of the standardized filtered PCM/FM systems: From FIG. 16 illustrated spectra it is noted that the Integrated Power from the adjacent channels falling into the desired channel may have a significant impact on the performance of the desired channel. In the referenced publications and patents the importance of Integrated Adjacent Channel Interference (ACI) is highlighted and described. For this reason the Power Spectral Density (PSD) and the ACI of Linearly (Lin) and of NLA transmitted FQPSK and GMSK signals is shown in FIG. 17. The PSD and Integrated ACI of hardware measured prototype FQPSK-B in a NLA transmitter and of a BRA linearized (Lin) transmit FQPSK is illustrated in the upper part of FIG. 17. In the lower part of FIG. 17 the Integrated Adjacent Channel Interference of FQPSK systems with that of GMSK systems is compared. In this figure "W" denotes the frequency spacing between Adjacent Channels. In case of GMSK which has been implemented with BRA embodiment described in this invention and designated as FGMSK having a Gaussian filter and bit duration (Tb) product of 0.25 has been used in the computed ACI result shown in FIG. 27. The computed ACI of a BTb=0.25 filtered system with considerably steeper filters than that of conventional Gaussian receive filters was simulated by JPL/NASA. The ACI curves for FQPSK-B and FQPSK-D1 as well as FQPSK-Lin are also included. Note from the results the significant(approximately 2 to 1 at -60dB) spectral ACI advantages of FQPSK over that of GMSK systems. Multi-state FQAM systems such as 16-state FQAM designated also as FQAM-16 and FQPSK.2.4 (the first number in this latter abbreviation indicates 2 nd generation FQPSK while the 2nd having 4 signaling states per I and per Q channel). In NLA systems have approximately double the spectral efficiency of the already-spectrally-efficient FQPSK systems including BRA systems operated in an FQPSK-B mode disclosed in this invention. The abbreviation "FQPSK-B" is a designation for cross-correlated FQPSK systems having an embodiment in which the TCS cross correlators are cascaded with LR filters operated in a BRA mode. The substantial spectral saving attained by 16-state FQPSK systems over alternative conventional 16-QAM pre-RF amplification filtered systems is illustrated by the computer-generated results shown in FIG. 18. In FIG. 18 the ACI results of illustrative FQPSK.2.4 (also designated as FQAM-16) state systems, obtained after fully saturated NLA, are compared with that of NLA conventional pre- modulation filtered 16-state QAM systems. The spectral efficiency advantage of the illustrated FQAM is more than 200% over that of prior art QAM at -30dB and FQAM has an even more significant spectrum advantage in terms of ACI at the critical -40dB to -60dB range. High performance systems require a robust BER performance in Additive White Gaussian Noise (AWGN) and also other interfering and noise environments. A frequently-used performance indication is the BER performance as a function of the available Energy of a Bit (Eb) to Noise Density (No) ratio. For RF power efficient as well as spectrally efficient systems having a robust BER, the NLA system performance in terms of BER = f(Eb/No) is specified for numerous system applications. In particular, in FIG. 19 the performance of FQPSK is highlighted. FIG. 19 The BER performance, in terms of BER=f(Eb/No), of prototype measurements and Computer design/ software generated data of FQPSK systems illustrated that NLA FQPSK is within about 0.5 dB of the ideal theoretical LIN amplified QPSK systems. Simple bit by bit detection as well as trellis decoding without redundancy has been used. In FIG. 19 curve (a) represents an ideal theoretical linearly (LIN) amplified system, while curve (b) represents a BER optimized NLA-FQPSK , and curve (c) represents a BRA and MM hardware-prototype measured FQPSK-B system performance, prior to optimization. Description of Exemplary Embodiments of Receivers and of Demodulators Receivers and Demodulators are described in this section. Signal reception, adaptive equalization, demodulation, fast and robust synchronization, bit recovery, Non Redundant Error Detection (NED), online in service monitoring, Non Redundant Error Control (NEC) and new architectures and embodiments for Bit Rate Agile (BRA) and NLA cross-correlated FQPSK, FQAM and related systems are disclosed in this part of the invention. In FIG. 20 a generic receiver and demodulator is shown. In this FIG. 20 demodulation of FQPSK type of signals, by using quadrature demodulation structures such as QPSK, QAM and OQPSK demodulation, enhanced by the architectures of the embodiment, illustrated in this figure is accomplished. Fast signal acquisition is attained and numerous other performance enhancements are achieved by the disclosed generic embodiment of this demodulator. Input port and lead 30.1 obtains a modulated signal from a receive input port. The optional BPF unit 30.2 is provided in some of the embodiments in which excessive strength out-of-band/or adjacent channel signals degrade the performance of the subsequent circuits if this "protection" or "roofing" BPF is not present. Automatic Gain Control (AGC) circuit 30.3 operates in a linear or in a nonlinear (NL) mode. For some applications an advantage of FQPSK and FQAM type of signals is that they are suitable for nonlinear AGC operation. From the prior art it is well known that nonlinearly operated AGC circuits such as "hard-limiters" and "soft-limiters" have faster AGC operation than their linear counterparts and in certain environments nonlinear AGCs outperform linear AGCs and in particular regarding "weak signal suppression" and also lead to reduction of Co-Channel Interference and of Inter-Symbol Interference (ISI) caused by certain RF delay spread - frequency selective faded environments. The optional AGC provides the quadrature demodulator 30.7 and follow-up signal processors including LPFs 30, Analog/Digital (A/D) 30.10, Symbol Timing Recovery (STR) 30.6, Adaptive Equalizer (AE) which could be a blind equalizer 30.11 and digital logic circuits decoders 30.12 to 30.17 the signals for demodulation and decoding. Additional signal processors which enhance the performance of the receiver/demodulator of this invention include one of the following: switchable changeable Carrier and Symbol Recovery unit 30.18, Pilot Extraction for unambiguous carrier recovery, fast AGC, and Automatic Frequency Control 30.19,. Non-Redundant Error Detection (NRED) unit 30.20, Diversity Switching Combining Controller 30.21 and Pseudo-Error On-Line Monitor 30.22 units are also included. FIG. 21 is a demodulator architecture also known as a "Block Demodulator" and/or digital demodulator or software demodulator. This implementation/embodiment is used for software or firmware or hardware, or combined hybrid implementations of this invention. On receive port/lead 31.1 the received RF signal or the received RF signal down-converted to a convenient IF frequency or to the baseband frequency range is shown. Unit 31.2 is an optional "roofing" BPF or other filter to protect the front end of the A/D 30.3 unit from out-of-band signal overload. The A/D provides serial or parallel signals for further digital processing, decision making and decoding in unit 31.4. The data is provided to output port 31.5. FIG. 22 shows Antenna Arrays (AA) in this multiple transmit and receive with omni and/or directional antenna embodiment. This architecture with Adaptive Antenna Arrays (AAA) has the potential to increases the NLA spectral efficiency of FQPSK, FQAM and FGMSK systems to more than 30 b/s/Hz by processing the transmit and/or receive antenna signals in a directional mode. An interesting prior art reference is Winters [23], which contains several system applications of system applications of conventional non-patented modulated systems. The potential advantage of the embodiment of FIG. 22 for FQAM and FGMSK systems as due to the fact that the FQPSK and FQAM type of systems are suitable for NLA power and RF spectral efficient robust performance operation with single, dual and multiple antennas. Larger number of AA further increases the spectral efficiency and thus capacity of the systems of this invention in specific geographic areas covered by the AAs and AAAs. FIG. 23 shows a Pseudo-Error (PE) on-line, or in-service monitor generic block diagram with on-line Probability of Error (Pe) monitor, diversity control, adaptive equalization control and Non-Redundant Error Control circuit also designated as Feher's Non-Redundant Error Control (FN) detection and correction. Non-intrusive on-line, also known as in-service bit error or Bit Error Rate (BER) or Probability of Error (Pe) monitoring of received signals has numerous benefits for the user of digital communication systems. Prior art references including Feher's [1 ,2,3] and the references contained therein describe the operational principles and some of the embodiments of the so-called "Pseudo-Error" on-line bit error detectors." While pseudo-error detection by itself is known from the prior art, pseudo-error monitoring of cross-correlated and filtered BRA systems combined with pseudo-error monitor generated control signal generation for adaptive equalization and/or diversity control techniques and embodiments are part of this new invention. Pseudo-Error (PE) operation, adaptive equalization and diversity control signal generation by PE generated signals is described in relation to FIG. 23. On lead 33.1 the received RF signal is present. This signal could be converted to a convenient IF and/or near the baseband frequency range and could be RF selective faded and/or corrupted by interference. In FIG. 23 an FQPSK received modulated signal is illustrated; other types of modulated signals could be also processed with the PE based structures of FIG. 23. In addition to signal distortion, exhibited in terms of ISI, caused by RF selective, time-dispersive propagation channels Interference 33.2 and Additive White Gaussian Noise(AWGN) 33.3 is assumed to be corrupting this system by having interference and AWGN added to the desired signal path in 33.4. Following the selective faded signal path and interference and noise, the power splitter 33.5 provides the signal to I Channel Demodulator 33.7, 33.8 and 33.9 and Q channel demodulator and to the Carrier Recovery(CR) unit 33.6. The regular demodulated and regenerated data is present as "Data out to parallel to serial converter" in the I and Q channels. The PE circuit or "Pseudo-error on-line detector " has at its input stage an input port, designated as a buffer amplifier 33.10, followed by the 33.11 LPF(Low-Pass Filter in the "pseudo" path (lower case "p" in the abbreviation) and the regenerator or threshold detector 33.12. Unit 33.13 is a clocked Exclusive-OR (ExOR) circuit which has the regular demodulated "Data out to parallel to serial converter" as one of its data inputs "In1" and has the regenerated data from the pseudo data regenerator 33.12 as its 2 nd data input "In2". The clocked ExOR circuit (the clock input is not drawn to the ExOR-to simplify the drawing) 33.13 provides binary pulses to the Pp(e) to P(e) converter 33.14. Unit 33.14 is implemented by simple logic and counter circuits and/or as part of a micro-processor and by software, hardware or firmware. Pseudo-Error(PE) implementations and their operating principles have been described in the literature, including references [1 ,2,3]. Unit 33.14 provides a signal to the Non Redundant Error Control (NREC) circuit 33.19, which is used, for display of the actual estimated Pe or BER of the data stream. Implementations of PE detectors, described in the aforementioned references, or variations of PE detector implementations used in this invention serve as Adaptive Equalizer(AE) control signal generators and Control Generators for Diversity Combining and/or fast synchronization systems. In one of the structures of this invention 33.14 provides one or more signal lines to the Adaptive Equalizer Controller 33.17 and in turn to the Adaptive Equalizer (AE) 33.18. The AE provides to output ports 33.20 and 33.21 control signals. In FIG.24 an implementation block diagram of a Pseudo-Error (PE) controlled IF adaptive equalizer of this invention, designated as Feher Equalizer ("FE") is shown. The elements, described in conjunction with FIG. 23, described previously are used in this structure of FIG. 24. At the input lead 34.1 the received RF or IF signal is provided to splitter 34.2. The splitter output, designated as i(t) is fed to a signal combiner 34.4b. The lower branch of the splitter provides an input to signal multiplier 34.3, followed by delay element D1 and the multiplied and delayed signal is fed to the second input of combiner 34.4b. The combiner output is fed to an IF to baseband quadrature demodulator unit 34.5. The multiplier unit 34.3 receives at its second input one or more control signal (s), designated as c1 (t) and generated by the PE monitor loop. The aforementioned multiplier 34.3 serves as a controlled signal attenuator, that is, it provides a time variable attenuation(or time variable gain) in the lower branch of the "one tap" adaptive IF equalizer comprising splitter 34.2, combiner 34.4b, multiplier (also designated as mixer) 34.3, delay element D1 34.4a and combiner unit 34.4b. The Demodulator 34.5 of FIG. 24 has a structure such as the I and Q channel demodulators shown in FIG. 23. The demodulated "eye" diagram (for definitions and terms such as eye diagram-see one of the references listed, including [1 , 2 or 3] ) through interface 34.6 provides the data output via threshold regenerator and logic 34.7 to output port 34.8 and the clock to 34.9, while the signals to the PE monitor are on leads 34.10 and 34.11. Single or multiple lead signals on lead(s) 34.13 are provided to LPF 34.12 for signal shaping and/or processing and for providing the aforementioned d (t) control signal to one of the inputs of the multiplier 34.3 of the adaptive equalization system. The operation of the adaptive Feher Equalizer (FE) shown in FIG. 24 operates in a baseband to IF feedback loop in which the control signal is generated by a PE detector. The PE signal is a binary fully regenerated signal thus it is not the same type of signal as used to control the coefficients of conventional adaptive taps of adaptive equalizers. FIG. 25 is a diagram of a multiple delay switchable Adaptive Equalizer (AE) designated as Feher Rake "FR". A Non-Redundant Error Control (NEC) detector, such as a Pseudo-Error (PE) circuit based NEC is used to generate one or multiple control signals, designated as "Control Select Signals". Received signal on lead 35.1 is provided to multiple splitter ports 35.2,35.6 and 35.10. The splitters provide signals to variable gain amplifiers A1 to An to provide signals to delay components D1 to Dn. The respective components are : 35.2 to 35.14. The upper and lower branches of the split signals are re-combined in adders 35.3, 35.7 and 35.11. The signal selection switch, Switch unit 35.14 selects one of the IF signals present at 35.3, 35.7 and 35.11 combiner outputs. The signal selection is controlled by the "Control Select Signals" generated by unit 35.21. The selected signal at the output port of switch 35.14 is provided to 35.15 demodulator and PE monitor NEC detector. Output port 35.16 provides signals to 35.19 Pseudo Error NEC detector additional processing and in turn for signal shaping by a LPF 35.20 for providing signals to the Control Select Generator 35.21. The FR is a combination of an adaptive Feher Equalizer (FE) with selectable and switchable delay components among several branches or "rake branches" of the receiver structure. In this embodiment the receiver operates based on the principle that if the PE detector and/or alternate NEC circuit has a relatively high Pe on line state then one or more of the component values of the delay elements will be switched out or in, that is selected, and similarly the gain values of the adaptive equalizer A1 , A2,..., An will be changed, continuously or in discrete steps. In FIG. 26 an implementation architecture for multiple Adaptive Feher Equalizers (FE) and Feher Rakes (FR) with one or more demodulators is illustrated. The received signal on lead 36.1 is provided to splitter port 36.2 and the splitter provides signals to units 36.3, 36.4 and 36.5. These units are FE and FR based on the previously described embodiments. These units provide signals to units 36.6,36.7 and 36.8 for multiple signal demodulation. Single or multiple PE monitor(s) 36.10 provide control signals to select by selection switch 36.9 the best signal. FIG. 27 shows a 2-branch diversity receiver with an adaptive equalizer and a single demodulator. In this embodiment FQPSK and/or FQPSK type of signals are first combined, in combiner unit 37.6 and are afterwards Adaptively Equalized in unit 37.7. Receiver antennas 37.1 and 37.2 provide signals to RF mixers/down-converters 37.3 and 37.5. Oscillator and/or Frequency Synthesizer 37.4 provides Carrier Wave signals for down-conversion. The IF down- converted signals are provided to combiner and/or switch unit 37.6, followed by adaptive equalizer 37.7, by optional Linear or NLA amplifier 37.8 and by Demodulator 37.9. The output demodulated data is available on port 37.10, the received/bit synchronized clock on port 37.11 and additional timing, such as symbol timing or block sequence timing on 37.12. One or more of the units and elements of this invention, described in conjunction with previous figures are used in the architecture of this FIG. 27. The PE and/or other NEC generated control signals provide for best possible combining, including "Equal Gain Combining", "Weighted Gain Combining", "Selective Combining" and other combining methods described in the prior art literature. A fundamental difference is that in this invention the actual Pseudo-Error rate is used as the pre dominant control signal generator and the PE monitor selects and/or combines the best performance BER signals, while the prior art combiners select or combine based on the received Carrier Power or received Carrier-to-Noise (C/N) ratio. Combining or selecting signals, based on received C/N or received carrier power (C) may lead to the selection of the inferior performance channel or combing with the wrong ratio or wrong weight, and in particular if the RF channel has serious frequency selective fades. For example the "main RF signal" designated RF main from antenna 37.1 has in one instant a much higher received carrier power than the carrier power on RF diversity antenna 37.2. Based on prior art receivers, combiners and diversity selection criteria the "main" signal would be selected as it has a higher C and thus higher C/N. However, in a severe RF selective faded environment even though the C power of the main branch, antenna 37.1 is much larger than that of the diversity antenna 37.2. In this instance the main antenna signal has much more RF frequency selective fade thus much worse performance the prior art receiver would choose/select the main branch with its poor and inferior performance, while the PE and/or other NEC based control signal disclosed in this invention would select the diversity signal with its superior performance.
