Abstract
A transmitted signal includes a pilot signal, a plurality of information signals and a carrier signal modulated by a modulating signal related in frequency to the pilot signal frequency. At a receiving station, the carrier signal is demodulated and the demodulated signal is used to generate a reference signal to translate the frequencies of the recovered pilot signal and the plurality of information signals by an amount sufficient to correct for undesirable frequency shifts which have occurred in the transmitted signal.
