ABSTRACT:
A communications system utilizing a noisy reference signal and a noisy information signal wherein the information signal is delayed from the reference signal as a function of the information modulation and then the two signals are combined for simultaneous transmission. The receiver amplifies the combined signal and delays it by a predetermined amount corresponding to the delay in the transmitter. The delayed and undelayed signals are autocorrelated to reconstruct the information signal. The system provides for autocorrelation of signals which have traveled a plurality of signal paths from transmitter to receiver.
