Abstract :
The Max-Log-MAP (MLM) algorithm is simple for turbo code decoding. Based on the algorithm a parallel array structure for turbo code decoding is suggested, which is easy to implement by VLSI. In this structure, flow direction of dates and computation process of the algorithm are obtained, the relation of nodes and date frames are analyzed, and the simple time sequencing of date operation is presented. The structure is proved by simulation
