Turbo code, also named Parallel Concatenated Convolutional Code (PCCC), is used for LTE (long term evolution) system for its good error correction ability and anti-interference ability. This paper presents the algorithm of MAP (Maximum A Posteriori probability) and improved MAP algorithm which based on SISO (soft input soft output).The ability of MAP algorithm and improved MAP algorithm are analyzed over the length of data for code, iterative times and complexity of decoding. Finally, the… CONTINUE READING
