Abstract
A transmitter-receiver system and a method for transmitting and receiving MCM signals, whereby any frequency offset and timing mismatch can be determined and corrected simultaneously, prior to demodulating the received signal. A plurality of single tone signals are transmitted prior to the transmission of the symbols corresponding to the desired information. The receiver is outfitted with a Frequency Offset and Timing Estimator for receiving theme plurality of single tone signals, estimating any frequency offset and timing mismatch and correcting the sampler and sampled signal accordingly, prior to demodulating the sampled signal.
