Co-channel interference and multipath propagation are two major difficult issues in mobile telecommunication system.Trellis-coded co-channel interference canceller(TCC)has been verified to be a very effective approach in solving these Problems. In TCC the desired signal and interference signal are simultaneously estimated by maximum likelihood sequence estimator. The Euclidean distance between transmitted sequences and their corresponding error sequences can be increased due to the introduction of TCM in the transmitters. This improves the BER performance even when the received signal constellation overlaps. The theoretical performance evaluation of TCC is, for the first time, presented in this paper. We evaluated the BER performance in quasi-static channel using an upper bound based on the transfer function.
