In order to mitigate the effect of co-channel interference in a radio communication system, the trellis-coded co-channel interference canceller(TCC) has been proposed and verified to be efficient. In TCC, trellis-coded modulation(TCM) is introduced to both the desired signal and the interference signal. A single maximun-likelihood sequence estimation(MLSE) is employed to estimate the sequences of both the desired signal and interference signal simultaneously. In this report, we propose a uniquely decodable code for TCC. Using this code, the minimum squared Euclidean distance(MSED) between received signal sequences is guaranteed to be nonzero. This enables TCC to decode the received signal uniquely which is not achieved by all the other conventional nonlinear cancellers.
