using Jakes model to simulate rayleigh channel fading

ecg matlab for medical instrument

说明：  单像素成像，利用随机抽样减少图像存储空间(Single-pixel imaging, using random sampling to reduce image storage space)

文件包含Clarke和Jakes信道模型详细的理论推导与区别，并附有完整代码，可以清晰认识两种常见无线模型。(The file includes two main channel models: Clarke Model and Jakes Model. The author has deduced these two models in great detail. Simulation code is also added to the file. It is very ueeful for the beginner.)

移动丝印到器件中心的skill程序，非常实用(move refdes to the center of symbol)

对图像进行DCT正反变换，可以在matlab里面观察正变换后的数据，达到数据压缩。(DCT pros and transform the image in matlab which observed data is transformed to achieve data compression.)

稀疏重构的理论基础和数值方法 （英文原版图书）(Theoretical Foundations and Numerical Methods for Sparse Recovery)

用MATLAB对电力系统进行仿真。里面有全套的仿真模型。(Using MATLAB for power system simulation. There are a full range of simulation models.)

通过matlab/simulink平台,得到IEC电压波动和闪变现象的仿真模型(The simulation model of voltage fluctuation and flicker of IEC is obtained through the matlab/simulink platform)

人脸检测的程序，效果不错！内附用法说明，调用一张图片，将现实出人脸的边缘。(code for facedetection，the performance is nice！ usage: I=double(imread c:Datagirl1.jpg )) detect_face(I) The function will display the bounding box if a face is found. )
