说明：  这个方案是非常基本的振幅调制和解调初学者实施。已作出评论。(This program constitutes of very basic amplitude modulation and demodulation implementation for beginners. Comments have been made. )

说明：  ＲＳ是分形中比较基本和比较重要的一块，希望这个程序对大家有所帮助，这是我网上找到的(RS is the fractal more basic and more important one, hope that this program be helpful to everyone, This is what I found online)

Robust control with matlab

this file contains a good program in matlab for HAR wavelet

channel modeling S*P(S parameter) to verilog module

主成分分析程序实现数据降维，能用比较少的变量解释大部分资料中的变异的几个新变量(Several new variables principal component analysis procedures to achieve data dimensionality reduction, most of the information in the variation can be explained by the relatively few variables)

电压型PWM整流器整流，svpwm，电压电流双环控制(Voltage type PWM rectifier rectification, svpwm, voltage and current double loop control)

This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet. For eg:-wavelets can be haar, db1, db2,dmey............... Decomposition can be viewed in figure. (Please note that select 256X256 image for better result.) Then compression can performed, PERFL2 give compression score. Then reconstruction can be performed. Each decompsition we can choose different threshold values. For each threshold value we can calculate mse,psnr,pq(picture quality), bit ratio etc. To get pq install pqs function . (This program compress and recostruct using wavelets.
