摘　　要：对Turbo码的编解码结构进行了阐述,并就MAP以及LOG-MAP解码解码算法进行了研究,并对LOG-MAP算法误码性能用MATLAB进行了迭代仿真。The structures of Turbo code's encoder and decoder are discussed in this paper. And MAP algorithm and LOG-MAP algorithm which are encoding and decoding methods of Turbo code are studied and performance of the later is simulated with MATLAB.
