摘要：

Turbo Codes is known as a powerful error correcting code[1]. Since the Turbo decoder reflects not only hard decision but also reliability of the received signals, the great coding gain can be obtained. In addition Maximum Likelihood Sequence Estimation (MLSE) with Adaptive Interference Cancellation (ATC) has been proved effective in reducing the influence of fading and cochannel interference[2]. Therefore, we propose a system that combines Turbo codes and RLS-MLSE The proposed system estimates Desired signal and Interference signal separately at MLSE part. The output of MLSE is estimated as the desired signal on survived path of Viterbi estimator, which is soft value. And then input the soft value that does not contain interference component to the Turbo-decoder. The simulation result shows that the proposed system has superior performance to the system with only MLSE.
