摘要
讨论了基于分组码的面向分组的Turbo码的编译码技术 ,包括编码结构、交织方式和MAP译码算法 ,并对基于分组的Turbo码性能进行了模拟比较 ,探讨了不同交织方式、不同交织长度和不同子码对码性能的影响。
The encoding and decoding techniques of block oriented turbo codes based on block sub codes are discussed in this paper,which include the encoding structure,interleaving scheme and MAP decoding algorithm.The comparision of performances is also made through computer simulation to investigate influences of different interleaving schemes,interleaver sizes and sub codes on the performance of the block oriented turbo codes.
