说明：  两种生成uwb信号的方法PPM-TH,PAM-DS。(Two methods of generating signals of uwb.One is PPM-TH, the other is PAM-DS。)

说明：  Opencv: Optical flow calculation using Block Matching method

这个是对一般信号进行快速傅里叶分析。并画出其幅频图和相频图。与原信号进行比较(This is the general signal fast Fourier analysis. And draw the amplitude frequency and phase frequency diagram. Comparing with the original signal)

基于小波变换的数字水印技术用于matlab实行(Based on Wavelet Transform Digital Watermarking Technology for matlab implementation)

利用Matlab语言编写的读取segy数据的小程序(Using Matlab language segy data read applet)

直接扩频通信是很重要的一种通信方式，他与卫星通信、光纤通信一并作为二十一世纪最伟大的发明，牛逼死了！(dsssDSSS is a very important form of communication, and satellite communication, optical fiber communication together as the greatest invention of the twenty-first century, died Niubi!)

很实用的matlab 教程，很详细 很实用的matlab 教程，很详细 很实用的matlab 教程，很详细(Practical matlab tutorial, very detailed and very practical matlab tutorial, very detailed and very practical matlab tutorial, very detailed)

生物医学信号处理是以数字信号处理为基础的离散信号及 离散系统的研究，因此．其预算过程基本上都是卷积或者相关预 算。在MATLAB中可以很容易实现这种运算。(Biomedical signal processing is based on digital signal processing discrete signals and discrete systems research, therefore. The budget process is basically the convolution or related budget. In MATLAB, can easily achieve this operation.)

说明：  SGA（Simple Genetic Algorithm）是一种强大的智能多变量优化算法，它模仿种群繁殖规律来进行 优化。 本SGA可以优化变量，求最小值,最大值（当把函数倒数也就求最小值啦） 并且支持浮点编码，grey编码，二进制编码；轮赌法选择，锦标赛选择；单点交叉，均布交叉，浮点交叉； 单点变异，浮点变异；(SGA (Simple Genetic Algorithm) is a powerful smart multi-variable optimization algorithm, which mimics the reproduction of law to be optimized. The SGA can be optimized variables, minimum, maximum, (when the function will last for the minimum is) and support for floating-point encoding, grey code, binary code round of betting method selection, tournament selection single-point crossover, uniform Cross, floating-point crossover single point mutation, floating-point mutation )

实现了用MUSIC方法来进行空间阵列信号的频率估计(MUSIC method implemented with the spatial array signal frequency estimation)
