Sparse representation based classification (SRC John Wright CVPR2009) 实现(Sparse representation based classification (SRC John Wright CVPR2009)‘s codes)

this is a algorithm Fast PCA, it is very suitable for beginer who want to understand PCA, it is demo step by step

说明：  使用matlab实现ofdm经过PA后在接收端进行失真抵消算法的仿真，其中调制方式包括mqam或mpsk(After the realization of OFDM using matlab at the receiving end after the PA distortion cancellation algorithm to carry out the simulation, which includes modulation MQAM or MPSK)

边缘是指图像中像素灰度有阶跃变化或屋顶状变化的那些像素的集合。学会并掌握使用matlab进行图像的边缘检测，设计用户界面实现上述功能。 实际问题： 1、采用matlab Guide设计图像界面，可以读入并显示图像，设计实现以下功能的菜单，点击相应的菜单（如radio button）在图像界面上可以显示相应的功能。 2 使用sobel检测算子； 3 使用prewitt检测算子； 4 使用canny检测算子； (Edge is refers to the image pixel has a step change in the collection of those pixels or roof shape change. Learn and master using matlab for image edge detection, design the user interface to realize the function. The real problem: 1, Guide design based on matlab image interface, can be read and displayed image, design and implement the following function menu, click on the corresponding menu (such as a radio button) in the image on the interface can display the corresponding function. 2 use the sobel detection operator 3 use prewitt detection operator 4 use the canny detection operator )

this code plots the performance of BPSK modulation in various fading channels like rician, rayleigh and awgn channels.
