Abstract:

A single antenna interference cancellation (SAIC) receiver was proposed for suppressing the co-channel interference (CCI) of cellular mobile communications system in frequency selective fading channels. The receiver with parallel structure detects each co-channel signal with a soft-input soft-output (SISO) detector separately. The soft information provided by the detectors and the decoders is used as the a priori information for the iterative cancellation of CCI. Its complexity only grows linearly with the number of co-channel signals. Simulation shows that the performance of the proposed scheme converges to that of the optimal receiver.

Key words: co-channel interference, single antenna interference cancellation, soft-input soft-output, iterative receiver
