ABSTRACT:
1. A binary digital communication system comprising a transmitter and receiver: said transmitter comprising means for alternately radiating in response to the digits of a binary message two signals of non-periodic energy which have been delayed by a predetermined amount with respect to one another, and means for phase shifting one of said signals by 180.degree. prior to radiation thereof in response to one of the "0" and "1" digits of the binary message; said receiver comprising means for receiving the signals alternately radiated by said transmitter, means for delaying the alternately received signals with respect to one another so they are brought back into correlation, and correlation-sensitive means to which the correlated received signals are fed, the output of said correlation-sensitive means being representative of said binary message.
