matlab仿真程序，有关正交频分复用（ofdm）的相关仿真(matlab simulation program, the orthogonal frequency division multiplexing (ofdm) related to simulation)

minmax filtering in matlab

这是一个很好的学习SIMULINK建模的基础教程，通过该课程的学习可以快速掌握SIMULINK的基本技巧。(This is a good basis for learning SIMULINK modeling tutorial, by the course of the study can quickly grasp the basic skills SIMULINK.)

光伏逆变器的simulink仿真程序，仿真没有问题,很有用的资料(Photovoltaic inverter Simulink simulation program, the simulation is no problem, very useful information )

MODBUS programEach instance of modbusgw acts a master to a modbus serial network. Currently each instance of modbusgw will only support one modbus serial network (future revisions will support multiple networks in a single gateway for now, it is necessary to start multiple instances).

LDPC BP译码算法在MATLAB中直接使用就行(matlab BP decoding)

能量熵的计算，均值便宜跟踪的示例，小波包分析提取振动信号中的特征频率。( Energy entropy calculation, Example tracking mean cheap, Wavelet packet analysis to extract vibration signal characteristic frequency.)

说明：  基于小波包的带通滤波器设计程序。给出了小波变换的快速算法和重构算法，讨论了应用小波变换进行信号带通滤波的方法，并通过正交小波包对信号的分解，把频率成分复杂的信号分解到各个频带上，根据需要提取指定频率的信号，然后用小波包重构算法对信号进行重构，实现对信号的提取。(Based on wavelet packet band-pass filter design program. Given the fast algorithm of wavelet transform and reconstruction algorithms are discussed using wavelet transform signal band-pass filtering method, and through the wavelet packet to signals can be decomposed, 把 frequency components of complex signal is decomposed into various frequency bands 上, according to need to extract the specified frequency signal, and then reconstructs the signal reconstruction algorithm to achieve the extraction of the signal.)

可以实现对混合喜好的主分量分析，这是在盲信号处理中队信号的迁出里非常有用(likePCA)
