自己编的一个简单的AR二阶模型，希望有用。(This is for AR(2) model.)

简单ofdm调制代码，基于qpsk，有循环前缀，两种信道传输。(ofdm simulation based on qpsk.)

编写一个简单的GUI 用于实现视频的读取，转换成灰度视频，最后显示出来。其中把视频每一帧彩色图像变换成灰度图像，并自动把灰度图像保存到当前生成的文件夹中，并合成灰度视频。 (Write a simple GUI for the video read, converted to grayscale video, and finally displayed. Wherein each of the video frame of a color image into a grayscale image and the grayscale image to automatically save the current folder is generated, and the synthesis of gray scale video.)

波束形成算法中的最小方差无失真响应波束形成器，并在一个图中给出常规波束和MVDR两种波形。 (Beamforming algorithm in the minimum variance distortionless response beamformer and give a diagram of conventional beamforming and MVDR two waveforms.)

遗传算法的编码实现 在MATLAB环境中(Coding Genetic Algorithm in the MATLAB environment)

用MATLAB编写求解伪距定位方程的程序，对实际数据进行处理，解算出接收机的位置及钟差信息。提供8个通道的两组数据如下，X, Y, Z 为WGS-84坐标系下各通道所跟踪卫星的坐标，Range为与之对应的校正后的伪距测量值。(Using MATLAB pseudorange positioning equation solver, and the actual data processing, solution and calculate the position of the receiver clock error information. 8 provides the following two data channels, X, Y, Z coordinates of the WGS-84 coordinate system of each channel of the satellite tracking, Range for the pseudo-range measurements corresponding corrected.)

说明：  脑电信号分析中的空间滤波器，分析节律信号非常有效。(EEG analysis of the spatial filter, analyze rhythm signal is very effective.)

很全置信度传播算法，对坐message passing的人很有用(Belief propagation algorithm)

THIS MATLAB CODE REDUCE THE SPECKLE NOISE IN SAR IMAGE, IT USE WAVELET FILTER THEN USED CASCADE THREE FILTERS IN TIME DOMAIN (HYBRID TIME AND FREQUENCY DOMAIN). THIS CODE NEED SOME MODIFICATIONS SINCE THERE ARE SOME PROBLEMS LIKE BY COMPUTE PSNR AND THE WAVELET HAS SOME ERRORS IN COMPUTE THE DE-NOISING

K-means is a clustering algorithm In the beginning we determine number of cluster K and we assume the centroid or center of these clusters. We can take any random objects as the initial centroids or the first K objects in sequence can also serve as the initial centroids. There are two function for that the kMeanCluster and distMatrix
