dc.description.abstractA new method to combat adjacent channel interference encoun­tered with multi-channel receivers is presented. In the case of a two­-channel receiver, there exits two crosstalk. paths which allow the desired signal to become present in the reference of the interference, thus traditional adaptive noise cancellation is ineffective. The two-channel receiver is similar to two-microphone systems used for speech enhancement. Models describing the baseband and passband crosstalk are developed. The Crosstalk Resistant Adaptive Noise Canceller (CTRANC). designed to work in the two-microphone case, fails when confronted with the two-channel receiver. A new system is proposed which uses a priori knowledge of the crosstalk gained by the injection of a known signal into the input of the receiver. This injection systems is then compared with the CTRANC for both baseband and passband systems by extensive computer simulation.
