SSB

二维经验模式分解，速度较快，不错的代码，希望对学习HHT的朋友有用(Two-dimensional empirical mode decomposition, fast, good code)

有信道编码，调制，信道估计等，可以得到很精确的幅值、频率、相位估计，应用小区域方差对比，程序简单。( Channel coding, modulation, channel estimation, You can get a very accurate amplitude, frequency, phase estimation, Application of small area variance comparison, simple procedures.)

this code source is avaible to lknkln,kln,

Matlab和VC混合编程，VC6.0工程设置，图文介绍很详细，在Matlab和VC混合编程中，这一步设置非常重要(Matlab and VC hybrid programming, VC6.0 engineering settings, graphic description is very detailed and hybrid programming in Matlab and VC, this step is quite important)

说明：  精度测试时延，基于原始套接字，高精度的测量，大学实验用很好(Socket)

对TXT文件数据进行读操作 写到excel文件(read TXT file then read in a new excel file)

Face Recognition Based on Polar Frequency Features

基于matlab的连续信号的实现，包括常见的抽样函数，矩形，三角等信号(Achieve the matlab continuous signal, including the common sampling function, rectangular, triangular signal)

说明：  本程序实现星光导航定位和定姿的仿真。定姿方法主要涉及最小二乘算法和TRAID算法。(This procedure Star navigation and positioning and attitude determination simulation.)

this is a image processing technique used for various process such as segmentation and enhancement
