Abstract
A method for adaptive signal communication on a wireless or wireline network is disclosed including detecting the communication environment or determining the communication requirements, for communication on the wireless or wireline network. The method may include determining system parameter information for adaptive Orthogonal Frequency Division Multiplexing (OFDM) based on the communication environment or communication requirements and encoding the system parameter information into at least one precoded cyclic prefix (PCP) sequence. The method further provides for generating an OFDM symbol transmission by combining at least one PCP, and an adaptive OFDM symbol, using the system parameters, then transmitting the signal from at least one OFDM transmitter to at least one OFDM receiver followed by demodulating the at least one PCP, and demodulate the OFDM signal using the system parameters recovered. A related OFDM system for implementing the method for a wireless or wireline network or platform is disclosed as are wireless or wireline devices operable with this method.
