ML法能够很好的估计信号的信噪比,GSM中GMSK调制信号的产生，小波包分析提取振动信号中的特征频率。( ML estimation method can be a good signal to noise ratio, GSM is GMSK modulation signal generation, Wavelet packet analysis to extract vibration signal characteristic frequency.)

个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。是主函数的源程序，优化函数则以m文件的形式放在fitness.m里面，对不同的优化函数只要修改fitness.m就可以了通用性很强。(Procedures is the most basic particle swarm optimization procedures, using Matlab realize, is very simple. Is the main function of the source, optimizing the function with m the form of documents on fitness.m inside, optimized for different functions as long as the modifications can fitness.m highly generic.)

中心极限定理的仿真，利用matlab实现，很好的例子啊(The Central Limit Theorem simulation using matlab to achieve a good example)

对双音信号的LUT基带数字预失真，功放采用saleh模型，附有各文件的组成说明。适合于深入学习功放线性化技术。该仿真对宽带和窄带都做了仿真，对窄带的效果更好，仍然有改进的余地。(This is a simulation program of Matlab for LUT digital baseband predistortion. It is helpful in learning High power amplifier linearity technology. Both of the narrowband and wideband situation is under simulation. The result shows that this shceme fits narrowband situation better.)

用matlab写的BP网络辨识函数，非常有用。(this is a program with matlab)
