摘要
分组乘积Turbo码(简称TPC码)是一类将分组码进行串行级联,并采用分组交织器构成的级联码,是一种构造十分简单的纠错码,它是香农信息理论提出后第一个在非零码率时可以实现无误码传输的纠错编码。采用迭代译码方法,可发挥该码的良好性能,并特别适合于高速硬件译码。良好的纠错性能使得TPC码正在被广泛的应用。本文首先对TPC码的编码结构和译码算法进行介绍,其后对TPC码的动态迭代译码进行分析与仿真,最后对其算法提出了优化方法。
Grouping Product Turbo Codes （TPC） is a kind of joining and correcting codes that is made of grouping interweaving implement and its construction is very simple. It is the first correcting codes that can realize transmission of no error code since Shannon has put forward communication theory. When we adopt this iteration coding means, TPC brings out good performance and especially suits high speed hardware coding. Because of its good correcting performance, now TPC has extensive application. The paper first introduces coding structure and coding algorithm of TPC. Second dynamic iteration coding algorithm of TPC has been analyzed and simulated. At last, a sort of optimizing method about its algorithm has been put forward.
