Electromagnetic, sound or ultrasonic wave communication system

Abstract

System for communicating electromagnetic, sound or ultrasonic waves The invention relates to a system (10) for communicating electromagnetic, sound or ultrasonic waves, comprising at least one transmitter (12) and a receiver (14), said at least one transmitter (12) being configured to transmit a plurality of distinct components of a signal, said components being of distinct and phase-coherent frequencies, the frequency difference between the components of each pair of components, capable of being obtained from said plurality of components, being greater than a predetermined frequency difference threshold, said receiver (14), knowing said distinct frequencies used by said at least one transmitter, being configured to: - receive, via an antenna, a multi-component signal, - eliminate, within said received multi-component signal,any incoherent component in phase with at least two components of the received signal associated respectively with at least two of said distinct frequencies.
