Signal-analysis

simulation BER in COHERENT use matlab GUI

I think this book will help you in signal processing

一个关于BPSK误码率仿真的程序，内容只包括误码率仿真部分！(One on BPSK BER simulation procedures, including the signal generated by adding Gaussian white noise, and bit error rate!)

Particle swarm optimization algorithm ( 粒子群优化算法)

说明：  三电平逆变器的建模，可以用于二极管钳位型三电平主电路的设计，采用的是SVPWM算法(Modeling of three level inverter)

matlab中最小二乘法拟合程序，很有用并且很简单的拟合程序(zxecf)

实现编码信号的转换。能够对不同的语音信号实现编码与解码。(Realizes the coded signal transformation. Can realize the code and the decoding to the different voice signal. )

说明：  MATLAB开发的计算机一个。直接运行即可。(MATLAB CALCULATOR)

It will ask for input the bit stream then generate pseudorandom bit sequence, finally give output as direct sequence spread spectrum

％绘制系统函数的零极点图 ％ ％pzplot(num,den) ％num为系统函数分子多项式的系数向量 ％den为系统函数分母多项式的系数向量 ％( Mapping system function pole zero diagram pzplot (num, den) num molecular function for the system polynomial coefficient vector den for the system function denominator polynomial coefficient vector)
