摘　　要：信道编码是实现现代可靠通信的关键技术之一,Turbo码就是最常用的一种。交织器和凿孔器都是Turbo码编码系统中重要的组成部分,二者对Turbo码编译码的性能都有着巨大的影响。本文采用了一种经过优化的Turbo码凿孔器方案,结合多种通信标准中的交织器方案,通过Matlab软件建立仿真模型的方法,研究此种凿孔器在不同交织器的作用下,Turbo码译码性能的变化,并绘制出译码误码率随信噪比变化的折线图。通过分析仿真图得出了此种凿孔器在不同交织标准下都具有比较优异性能的结论。Channel coding is one of key technologies to improving transmission reliability of modern communication,Turbo codes is the most widely known.Interleaver and puncture are all important components of Turbo codes encoding system and they have a huge influence on encoding and decoding performance.In this paper,it researched changes in the decoding performance of Turbo codes on the basis of an optimized puncture with the effect of different interleaver adopted in many communication standards by the Matlab simulation method,the line charts of the relationship between decoding error rate with SNR were drawn.It is concluded that the optimized puncture has great performance under different interleaver standards by analyzing simulation diagrams.
