这些程序是奥本海姆版数字信号处理书中全部常用的函数，非常方便大家使用。(These procedures are the Oppenheim book all commonly used digital signal processing function, and very easy to use. )

基于matlab 搭建的跳频系统的源代码。(Frequency hopping systems built based on matlab source code.)

说明：  人脸识别 人脸图像特征提取与对比 pca(Face image feature extraction and comparison, image recognition, principal component analysis)

说明：  计算关联维的 Matlab 程序 - (mex 函数，超快) ----------------------------------- 文件夹说明： 1、CorrelationDimension_main.m - 程序主文件 2、LorenzData.dll - 产生Lorenz离散数据 3、normalize_1.m - 数据归一化 4、PhaSpaRecon.m - 相空间重构 5、CorrelationDimension.dll - 计算关联积分函数 6、CorrDim_buffer.dll - 缓存文件(calculated the correlation dimension Matlab procedures- (mex function, ultrafast)----------------------------------- folder Note : 1, CorrelationDimension_main.m-procedure two main documents, LorenzData.dll- Lorenz have three discrete data, normalize_1.m-normalized data of four, PhaSpaRecon.m-5 reconstruction phase space, CorrelationDimension.dll-associated integral calculation Function 6, CorrDim_buffer.dll-cache file)

本压缩包包括OFDM系统的信道估计理论与matlab仿真程序两部分，其中m文件为仿真程序。(The archive includes OFDM system channel estimation theory matlab simulation program with two parts, one m file for the simulation program.)

this package is very useful. for those student doing project in ns2 software it is very helpful

its a matlab discription of varius digitl filers both in special and frequency domain. very useful for beginners.

信号在高斯信道下的仿真，本人自己编的，已经经过验证是正确的(The simulation signal under the Gauss channel, I own, has been verified to be correct)

matlab实现经纬度坐标转换，代码效率较高(matlab realize the latitude and longitude coordinates conversion)
