摘要

摘要: 该文在分析了非二进制Turbo码的译码算法的基础上，提出了非二进制Turbo码和具有良好纠突发错误的RS码级联的非二进制Turbo级联码系统模型。该系统采用缩短的RS码(204, 188)作为外码，非二进制Turbo码作为内码的串行级联方式，内码和外码之间用深度为12的交织器隔开，译码时, 非二进制Turbo码分别采用Symbol-by-Symbol Log-MAP和SOVA算法。仿真结果显示，与二进制Turbo级联码系统相比，该系统具有误码率低，延时时间短，频带利用率高等优点。

Abstract: A novel system model using a non-binary Turbo concatenated codes is proposed based on analysis about the decoding algorithm of the non-binary Turbo codes in this paper. A shorted RS code(204,188)as outer code and a non-binary Turbo code as a inner code is separated in the system , Symbol-by-Symbol Log-MAP and SOVA algorithm is used in decoding the non-binary Turbo code .The conclusion by simulating is that proposed system has the features of low bit error ratio, low latency and high spectral, etc, compared to the other concatenated codes systems.
