| 摘 要： | 深空测控中为获得较高的编码增益需要用到信道编译码技术。Turbo码是一种逼近香农限的高性能的信道编译码,其中,交织器的设计是影响Turbo码性能的关键因素之一。论述了交织器设计的基本准则,并详细介绍了3种常见的随机性交织器:伪随机交织器、S随机交织器和S改进型交织器的交织原理,对比分析了3种交织器的优缺点并给出了仿真结果。结果表明,交织器生成方式的不同将带来不同的Turbo码译码性能。

| Abstract: | In order to acquire high coding gains in deep-space exploration,the channel coding/decoding technology is used.Turbo code is a kind of channel coding/decoding with high performance which can approach Shannon limit.The design on interleavers is one of the key factors which can affect the Turbo code's performance.This paper describes the basic principle of designing interleavers,and then introduces in detail such three common interleavers as pseudo-random,S-random and S-improved interleavers.Finally,the three... |
