空间平滑算法估计相干信号DOA，还有基于此的改进算法，大家可尝试(DOA estimation)

本程序基于Matlab，可以对特定波长光线在透镜系统中进行光线追迹。可以生成任意方向平行光，点光源任意角度光线，并对全反射，光线射出系统等特殊情况用红色标出。透镜数任意，透镜参数可设。(The program is based on Matlab, with a specific wavelength of light in the lens system for ray tracing. Parallel light can be generated in any direction, at any angle point source of light, and the reflection of light injection system and other special circumstances marked in red. Any number of lenses, lens parameters can be set.)

OFDM系统的整个流程，用MATLAB编写的程序(The whole process of OFDM system, using MATLAB program )

说明：  自适应中值滤波器的滤波方式和传统的中值滤波器一样,都使用一个矩形区域的窗口Sxy,不同的是在滤波过程中,自适应滤波器会根据一定的设定条件改变(即增加)滤窗的大小,同时当判断滤窗中心的像素是噪声时,该值用中值代替,否则不改变其当前像素值,这样用滤波器的输出来替代像素(x,y)处(即目前滤窗中心的坐标)的值。(Adaptive Median Filter for filtering methods and the same as the traditional median filter, use a rectangular area of the window Sxy, different in the filtering process, the adaptive filter in on certain Presumed Conditions change (an increase of ) filter window size, while when the judge is the filter window center pixel noise, the median value is used instead of, or does not change its current pixel value, so that the output with a filter to replace the pixels (x, y) Office (that is, coordinates of the current filter window centered) values.)

产生两个均值为m,方差为sgma的高斯随机变量，当输入参数只有一个时，认为均值为0。(mean to have two m, sgma variance for the Gaussian random variables, when only one input parameters, that the mean of 0.)

解决图像配准中遇到的解六个参数的非线性方程组，非常好用。(Solve nonlinear equations of the six parameters of image registration encountered, very easy to use.)

自己写的matlab源码，实现EMD分解，原始的EMD分解代码，简单实用。(Write their own Matlab source, EMD decomposition, the original EMD decomposition code, simple and practical.)

基于小波域自适应水印图像的（嵌入） matlab编程 (Wavelet based image adaptive watermarking (embedding) matlab programming)
