宽带信号的空间谱估计以及信噪比等对信号估计的影响，才用聚焦矩阵的方法，采用的聚焦矩阵不同，性能也不同，这里是RSS算法(Spatial spectrum estimation of wideband signals and SNR of the estimated impact on the signal only with the focusing matrix method, using the focusing matrix of different, performance is different, here is the RSS algorithm)

说明：  HFSS学习示例，十分有用，简单易懂，值得拥有(Learning example, simple and easy to understand, very useful, it is worth having )

选择二进制编码，利用遗传算法计算函数的最小值(calculate function minimum with genetic algorithm)

wavelet transform matlab code

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。)

MATLAB CODE FOR SEGEMNT

最速下降法是一种沿着N维目标函数的负梯度方向搜索最小值的方法。该程序是用最速下降法求无约束最优化解。(Steepest descent method is an N-dimensional objective function along the negative gradient direction of the minimum search method. The program is used steepest descent method for unconstrained optimal resolve.)

基于chebyshev的水声信号分析，小波包分析提取振动信号中的特征频率，多抽样率信号处理。( Based chebyshev underwater acoustic signal analysis, Wavelet packet analysis to extract vibration signal characteristic frequency, Multirate signal processing.)

用matlab实现的聚类，效果很好，里面有部分数据，点击可以直接运行(Cluster with matlab to achieve good results, which are part of the data, click directly run)

直扩通信的MATLAB仿真，可以在此基础上进行各种性能仿真。(Direct Sequence Spread Spectrum Communication MATLAB simulation, can be conducted on the basis of various performance simulation.)
