【 摘 要 】

Based on the analysis and simulation of TPC codec principle and iteration decoding algorithm based on Chase 2, the design and implementation methods of TPC encoder and decoder are presented in this paper. In particular, circuit design and implementation flow of soft-input soft-output modified method in decoder algorithm and iteration decoding are analyzed. Aiming at (64,57,4) TPC, when the iteration times is 3 and the uncertain position number is 3, simulation and implementation results show that at least 6.8dB encoding gain can be obtained under the condition of BER=10-6
