This paper describes two new matrix transform algorithms for the Max-Log-MAP decoding of turbo codes. In the proposed algorithms, the successive decoding procedures carried out in the conventional Max-Log-MAP algorithm are performed in parallel, and well formulated into a set of simple and regular matrix operations, which can therefore considerably speed up(More)
Two simplified MAP algorithms for iterative decoding of turbo codes are presented. By using a parameter “decoding depth”, our algorithms do not require computation of the aposteriori probability of each decoded information bit throughout the entire trellis, thus reduce the computational complexity and decoding delay considerably. One of the algorithms can(More)
