Claim Text:
1. An FHFMSS (Frequency Hopped Frequency Modulation Spread Spectrum) Multiple accessing transmitter system comprised of: a baseband modulation subsystem for receiving and modulating a first input data signal providing, in general complex valued, a first information baseband symbols; a FHFMSS modulation subsystem receiving a first information baseband symbols for providing a first baseband FHFMSS signal wherein the FHFMSS modulation subsystem is further comprised of: a code generation subsystem for generating a multiplicity M sequences of code vectors wherein M is an integer greater than or equal to 1; a frequency synthesizer for generating a multiplicity M periodic waveforms with frequencies that are distinct integer multiples of a fundamental frequency on the basis of the multiplicity M sequences of code vectors; a first frequency modulation (FM) modulator modulating the multiplicity M periodic waveforms for generation of a first Frequency Hopped Frequency Modulation (FHFM) spreading waveform; and a spread spectrum modulator modulating the first FHFM spreading waveform by the first information baseband symbols for generation of the first baseband FHFMSS signal.
