基本粒子群优化算法Matlab源程序 网上找到的别人做的很简单的程序，写的很精练很工整，据说优化效果不是很理想，由于没有时间去做很多测试，所以就先摆在这里，但愿以后能用得上。 下面是主函数的源程序，优化函数则以m文件的形式放在fitness.m里面，对不同的优化函数只要修改fitness.m就可以了通用性很强。 (Particle Swarm Optimization Algorithm Matlab source code online to find others to do the procedure is very simple, very concise writing is very neat, is said to optimize the effect is not very satisfactory, because there is no time to do a lot of testing, so I have to put in here, I hope that can use later. The following is the main function of the source, optimizing the function form of the document on Zeyi m fitness.m inside, as long as the different optimization functions can modify the fitness.m highly generic.)

在MATLAB环境下使用谱减法对语音信号进行增强，程序可以运行(In the MATLAB environment using spectral subtraction speech signal enhancement program can run)

lmd 采用滑动平均处理，调整过，可以直接运行出图。(lmd hua dong pingjun)

说明：  基于fuzzy c-means（FCM）的无监督模糊聚类算法，输出值有：各个样本的类别标签、目标函数在每次迭代后的值、聚类中心以及聚类区间。内有测试数据data.mat，点击 test.m 可以完美运行。(The unsupervised fuzzy clustering algorithm based on fuzzy c-means (FCM) outputs the class labels of each sample, the value of the target function after each iteration, the clustering center and the clustering interval. There is test data ('data.mat') inside, click ' test.m' to be able to run perfectly.)

仿真信号处理。。实现维纳滤波。。用MATLAB实现，。。。(Simulation of signal processing. . Wiener filter to achieve. . Using MATLAB realization. . .)

网上掏了个BCH编码及译码程序，觉得不错，现于大家分享，希望对你有用(BCH out a line coding and decoding process, feel good, is to share in the hope that useful to you)

用MATLAB，对OFDM系统进行仿真，其中的信号为BPSK信号。(using MATLAB, the OFDM system simulation, the signal for BPSK signals.)

极化SAR，读取San Francisco地区数据的读程序，在Pauli分解合成San Francisco的RGB图中有调用到(Polarization SAR reading program, read the San Francisco area data call to the Pauli decomposition a synthetic San Francisco RGB figure)

GPS_SDR:GPS软件接收机源码，包括从中频数据获取到捕获、跟踪、解码、定位和界面显示。(GPS_SDR: GPS software receiver source, including data acquisition from the IF to the acquisition, tracking, decoding, positioning, and screen displays.)
