Abstract

The invention relates to a circuit for suppressing reciprocal interference between transceivers for radio communications which operate in the same band and are physically close to each other, comprising means for sampling part of the signal transmitted by a first transceiver to be used as the reference signal; means for sampling part of the received signal obtained from a receiving aerial, to be used as the disturbance signal; means for correlating the reference signal with the disturbance signal and extracting their data regarding phase and amplitude; means for receiving the reference signal and for rotating its phase and varying its amplitude according to the phase and amplitude data supplied by the said correlation means; and adding means for adding together the received signal and the reference signal and injecting them into the receiving line in phase opposition to the disturbance signal with a modulus suitable for cancelling the disturbance signal.
