摘　　要：针对Turbo码MAP译码算法运算量、存储量大和译码延时长的问题,基于双滑动窗的基本思想,提出一种高速并行的译码算法。计算机仿真表明,该算法是存储量与译码性能的良好折衷。This paper researches on the problem about large calculation and storage complexity, long decoding delay of the MAP algorithm and proposes a high speed parallel decoding algorithm for Turbo codes based on double sliding window method. Simulation results show this algorithm performs a good tradeoffbetween storage complexity and decoding performance.
