本代码是关于数字信号处理中的频谱泄露现象及其带来的危害的MATLAB仿真。用到的窗函数的是矩形窗和海明窗。(The code is on the digital signal processing of the spectrum and its disclosure of the hazards brought about by MATLAB simulation. Window function used is the rectangular window and Hamming window.)

用matlab实现的自适应中值滤波代码。(Matlab implementation by the adaptive median filter code.)

用MATLAB编写的中值滤波程序，几乎囊括了所有中值滤波的类型，很全的哦。并包含测试的LENA图像。(Written using MATLAB median filter program, covering almost all of the type of median filter, it is full of oh. And includes tests LENA image.)

希望给辛苦科研的人带来一点点帮助--学习因子可以变化的PSO算法，不再是c1=c2=2，粒子进化更加灵活，下面是学习因子同步变化的pso，调用形式为[xm,fv]=LNCPSO(fitness,N,cmax,cmin,w,M,D)(People who want to work hard to bring a little bit of research to help- learning factor can vary PSO algorithm is no longer c1 = c2 = 2, particle evolution is more flexible, learning factor is below synchronous changes pso, calling in the form of [xm, fv] = LNCPSO (fitness, N, cmax, cmin, w, M, D))

数字信号处理实验教程中的例子(MATLAB版)，挺全的……(Experimental Course of Digital Signal Processing (MATLAB version))

用FDTD的方法对3维光子晶体的光子带隙进行模拟，得要直观图。 程序用MATLAB编写。(With the FDTD method on three-dimensional photonic band gap photonic crystal simulation, may be visual map. Programs written with MATLAB.)

空间谱估计（郑志东） 的程序 很多章 全( Spatial spectrum estimation (Zheng Zhidong) program many chapters all)

说明：  一种求邻接矩阵的普通算法，这是通用程序，要注意变量的更改。(A Method for the adjacency matrix of the general algorithm, which is common procedure, to pay attention to the variable changes.)

，对于一个使用相关器的二进制通信系统，用monte carlo仿真估计Pe并且画出Pe与SNR的对比图~(for a binary communication systerm，use monte carlo simulation draw the Pe and the compared of Pe and SNR~)
