卷积码编码以及8PSK调制解调程序，卷积码编码采用（7,5）生成多项式的（2,1,3）编码结构(Convolution coding and 8PSK modulation and demodulation process)

QPSK是通信信道中一种很好的调制方式，对于其性能参数进行了仿真，信道以及噪声选择可以根据代码自由改动。对学习无线编码很有用处。(QPSK is a good communication channel modulation, the performance parameters for the simulation, channel and noise free choice can be altered according to the code. Learning wireless encoding useful.)

本文介绍了开放腔的基本原理和数学计算软件MATLAB。从四种基本腔体 模型出发，给出了用MATLAB设计开放腔高频参数计算软件的一般过程和方法， 并开发了开放腔计算分析软件。利用这一软件对四种不同类型开放腔进行了数 值计算分析，并将结果与实验测试和其他文献的计算结果进行了比较。结果表 明，本文的分析计算结果与实验以及文献[1]的分析计算结果有较好的一致性， 而本文提供的用MATLAB进行开放腔高频参数计算的方法简单易用、方便可靠、 计算效率高，是工程设计分析的一种快捷实用的手段。(This article describes the basic principles of open cavity and mathematical computing software MATLAB. Cavity from the four basic models starting with a given frequency open cavity design parameters MATLAB computing software and methods of the general process and the development of the open cavity analysis software. Using this software, four different types of open cavity of a numerical calculation and analysis, and the results with the experimental results and other literature were compared. The results show that the analytical results with experimental and literature [1] of the analytical results are in good agreement, and this provides an open cavity with the MATLAB high-frequency parameter calculation method is simple to use, convenient and reliable, the computational efficiency high, is the engineering design of a quick and practical means. )

说明：  本文件主要是针对于粒子群算法在matlab环境中地应用说编写地m文件！其中粒子群算法地目标函数可在源程序中自行更改！ -(this document is mainly targeted at PSO algorithm in Matlab environment application to the preparation of that document m! )

in this m file i have identified a system in the dynamic form.
