粒子群算法初步讲解，粒子群算法分类，标准粒子群算法的实现(Preliminary analysis of particle swarm optimization)

Matlab 二维离散余弦变换的图像压缩(Matlab dimensional discrete cosine transform image compression)

M和m序列发生器，用于扩频通信中产生长度为2^N和2^N-1的伪随机码。同时还有产生bpsk调制的扩频调制和解调系统仿真，以及gold码的mat文件。(M and m sequence generator.Used for spread spectrum communication to generate the spread code.As well as bpsk spread spectrum system communication simulation.)

该文件包含一些常用的无线网络定位基本算法，如TDOA、TOA和AOA。(Basic wireless positioning algorithm )

一束光通过一个透明圆柱体，圆柱后有一个屏幕，程序最终反映屏幕上的 图象随圆柱半径的变化而变化。其中光强分布是采用相干叠加原理，因为其中采 样点数目不足，所以光强分布的结果和真实的有一定差距。增加采样点数目和改 变采样点范围能够改善输出光强的结果逼真程度。(一束光through a transparent cylinder, a cylindrical post-screen process will ultimately reflect the on-screen image with the cylindrical radius change. Light intensity distribution of which is the principle of coherent superposition, because the insufficient number of sampling points, so light intensity distribution of the results and have some real gaps. Increase in the number of sampling points and to change the scope of sampling points can improve the outcome of the output light intensity the degree of realism.)

实现了L=3，h=0.5,M,RC升余弦CPM调制(Achieve L = 3, RC raised cosine CPM modulation)
