有关粒子群算法的简单编程，对于初学粒子群的人很有帮助(The particle swarm algorithm is simple program for beginners who PSO helpful)

GENERATING NOISY IMAGES BY USING NOISE FILTERS : GAUSSIAN, UNIFORM, SALT&PEPPER

本书为经典的非线性系统书籍，1996年出版。(This book is a classic nonlinear system books, published in 1996.)

说明：  微弱信号的提取检测和分析 用matlab实现的源代码 首先计算输入信号的均值、均方值、方差、频谱及功率谱密度，确定输入信号中包含着有用信号。然后提取有用信号，并要求计算提取信号的均值、均方值、方差、概率密度、频谱及功率谱密度，并画出曲线(The extraction of weak signal detection and analysis)

说明：  小波变换去噪的程序，很好用，也很经典的承训(Wavelet denoising procedure, easy to use, and very classic Cheng Xun)

OSTBC 准正交空时分组码多天线系统，QPSK，QAM调制的误码率比较
