A communication system wherein known data sequences characterise both wanted transmitted signals and interfering co-channel transmitted signals, comprising a receiver for receiving a wanted transmitted signal in the presence of unwanted co-channel interfering signals comprises signal sequence identifier means which includes a store for known data sequences and a correlator which serves to correlate received signals with the stored known data sequences, whereby the relative location in time of received signal sequences is identified, impulse response estimator means operative for estimating the impulse response of each signal the location of which has been identified, means responsive to the estimated impulse responses for producing in respect of each said response a set of possible signal configurations, and detector means including means for comparing the signals of each set with the received signal thereby to filter the wanted signal. <IMAGE> |
