Patent ID: 8565063

Claim:
A method for adaptive signal communication on a wireless or wireline network based on transmitter-receiver adaptation and interaction comprising the following steps for transmission and reception of an adaptive communication signal: at a transmitter: (a) detecting the communication environment and determining communication requirements by a common interface device from at least one local information source and controlling information received by the local receiver from a remote transmitter, for combined communication supporting at least one data stream on the wireless or wireline network; (b) determining system transmission parameter information for adaptive Orthogonal Frequency Division Multiplexing (OFDM) transmission based on the communication environment or communication requirements in (a); (c) dynamically encoding a binary sequence to represent a transmission scheme associated with the system transmission parameter information in (b); (d) generating complex precoded cyclic prefix (PCP) providing an identification element and a system transmission parameter element based on the selected binary sequence in (c); (e) generating a PCP-OFDM symbol transmission by combining in a communication signal (i) the at least one encoded PCP sequence, and (ii) an adaptive OFDM symbol without introducing any repetition of the OFDM symbol itself, wherein the adaptive OFDM symbol is generated with the data to be transmitted and the system transmission parameters encoded in the encoded PCP, thereby enabling adaptive transmission of the data based on the system parameters affecting the transmission; (f) transmitting the communication signal from at least one OFDM transmitter to at least one OFDM receiver; and at a receiver: (g) receiving the communication signal and demodulating the at least one PCP to retrieve the system parameter information encoded into the PCP and estimating communication channel; (h) demodulating the OFDM symbol and dividing the recovered combined data stream into original multiple form using the identification and system parameters recovered in step (g), after cancelling the interference from PCP to data-carrying OFDM signal using recovered PCP and channel in (g) and equalizing the received signal; and (i) communicating controlling information to the local transmitter; wherein the binary sequence includes a pseudo random sequence comprising one of an m-sequence, a Gold sequence or a Kasami sequence, and the interactive operation of an OFDM transmitter or receiver is enabled by the system transmission parameter information encoded into the PCP, the identification element of the PCP being a wireless or wireline communication transmitter identification.
