Turbo 乘积码也有着较强的随机纠错性能，但目前关于其 混合纠错能力方面的研究还较为少见. 在分析 Turbo 乘积码突发纠错能力的基础上，将突发错误参数对 TPC 纠正混合错 −4 误性能的影响进行仿真分析，并与相同码率、相同码长的 RS 码进行对比. 仿真结果表明，Turbo 乘积码在 BER 为 10 处可以获得近 3.5 dB 的编码增益，这意味着节省近 55%的码元能量，是一种适合于解决混合错误的差错控制编码技术. 关键词：Turbo 乘积码；RS 码；无线通信；突发错误；混合错误；纠错性能 中图分类号：TN911 文献标志码：A 文章编号：1009-671X （2012 ）03-0015-05 Performance comparison of hybrid error correction between Turbo product code and Reed-Solomon code FU Hongya, DANG Xiaoyu College of Electronic and Information Engineering, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China Abstract ：Because of various fading modes in wireless channel, there are both random and burst errors in wireless communication systems. To correct the errors, reed-solomon （RS ） codes are often considered. Turbo product code has also a strong random error correction performance, but the study of its hybrid error correction capability has rarely been reported at present. Based on the analysis of burst error performance of turbo product code (TPC), simulations of TPC with burst error parameters were performed, and the results were compared with RS code at the same rate and the same code length. It is shown
