摘要
提出了Turbo乘积码的并行迭代译码原理,对比分析了一种新的并行迭代译码器和传统的串行译码器,给出了以扩展汉明码(32,26,4)、(64,57,4)为子码的二维Turbo乘积码(32,26,4)2、(64,57,4)2在通过两种不同的译码器时的仿真结果。仿真结果表明,采取并行迭代译码器,在保持同样的译码性能的同时降低了译码延时。
This paper presents the principle of parallel iterative decoding of Turbo Product Codes(TPCs), comparatively analysizes a kind of new parallel iterative decoder and traditional serial decoder.Finally,the simulation results of 2-D Turbo Product Codes (32,26,4)~2,(64,57,4)~2 based on a subcode of extended Hamming (32,26,4),(64,57,4) with two classes of iterative decoder are given.The results show that with the new parallel approach, decoding latency of TPCs can be halved while maintaining virtually the same performance level.
