基本的粒子群优化算法程序，用Matlab实现，非常简单。(pso code)

说明：  简要介绍了一下纠错编码的相关基础知识,主要介绍了线性分组码，卷积码，循环码等等(A brief introduction about the basics of error correction coding of the relevant)

伪随机码或称PN码，是扩频通信中不可缺少的一种序列。扩频通信，简单的说来就是通过一组相关性很强的伪随机序列，使原有的信号按照伪随机序列的特性出现。(Said pseudo-random code or PN code, spread spectrum communication is an indispensable sequence. Spectrum, simple to say is highly relevant by a group of pseudo-random sequence, so that the original signal in accordance with the characteristics of pseudo-random sequence appears.)
