N2 - We propose an architecture which reduce the circuit size to concurrently cancel co-channel interference and image-band interference. We adopt analogue Hilbert transformers to cancel image-band interference and adaptive array antennas to cancel co-channel interference. Furthermore, we can miniaturize the receiver by mixing all signals at the IF stage. We also show performance of the proposed system by computer simulation. As a result, image-band interference caused by some imperfection of Hilbert transformer can be completely canceled. Moreover, co-channel interference can be simultaneously canceled.
