ABSTRACT:
A listener echo canceller for a receiver made to receive data symbols a.sub.n transmitted at regular time intervals T. The received wave is first conventionally decoded to derive the received symbols therefrom, said symbols are the subjected to a bulk delay which has been determined for shifting the listener echo impulse response to the time reference origin. The delayed symbols are then processed to generate an echo replica which replica is then fedback to the decoder input for being subtracted therefrom.
