LMS算法和NLMS算法的比较。模拟的是回声消除。但没办法消除回声，只能做有限的处理。(LMS algorithm and NLMS algorithms. Simulate the echo cancellation. But no way to eliminate echo, can do only limited processing.)

MATLAB 通信原理ask调制源代码文件 (Communication Theory ask modulation MATLAB source code files)

计算采用MATLAB并画出匹配波波形器的压缩输出(Calculated and drawn to match the compressed output waveform)

fsk 使用matlab进行二进制振幅调制(fsk using matlab binary amplitude modulation)

window 下的lua源码，值得学习,欢迎大家一起学习，下载(lua source window down, it is worth learning, welcome everyone to learn together, to download)

mathmatics学习资料,比较实用,亲身感受(mathmatics learning materials, more practical, personal experience)

这个代码是用matlab编程实现产生一个复指数序列、方波序列、单位阶跃序列单位冲击等几个序列(This code is to use matlab programs have a complex index series, square wave sequences, unit step representation unit and so on several series sequence impact )

说明：  通过matlab五电平调制，实现更优选择的切换(Through five level modulation, better switching can be achieved)

一个带有子系统的PID仿真，基于Matlab Simulink(Simulation of PID controller, based on Matlab Simulink)
