Contourlet transform and feature extraction

说明：  基于TDOA声源定位算法仿真–MATLAB仿真(Simulation of acoustic source location algorithm based on TDOA - matlab simulation)

time series In this example we will use a synthetic data set. To create our synthetic data we will make our unit of time 1000 years = 1 ky and sample a 500,000 year record in 2 ky increments. We first create a vector containing the times:

运用盲均衡cma算法来实现源信号的恢复，效果明显4QAM(cma test blind equalization)

通过Matlab/simulink对boost电路进行编程，实现了输出电压的PI控制。对输出电压可以任意调节(By Matlab/simulink for boost circuit programming, the PI control of the output voltage. The output voltage can be adjusted)

可以按一定规律插入一些数字的一个很小的程序(Can insert a certain number of rules a small program)

说明：  提供了通信系统仿真链路的基本知识,对通信系统仿真初学者很有用。(show the base knowledge on the simulation of communiaction link.)

通过对视频的适当修改，运用matlab软件实现视频图片提取。(chang video into image with matlab)

用前向平滑的MUSIC算法进行入射信号源到达角的估计。(a forward smooth music method for doa estimation.)

Root-mean-square error and mean-square signal-to-noise ratio F(x,y) the original image , F’(x,y) the decompressed image , the original image change to JPG and then JPG change to Im. Observe to Error- ratio.
