基于matlab的leach算法的原代码，在无线传感器网络簇头算法中有很大的优势。(The leach-based algorithm matlab source code, the cluster head algorithm for wireless sensor networks have great advantages.)

频域波束形成频域波束形成频域波束形成频域波束形成(Frequency domain beamforming frequency domain beamforming frequency domain beamforming)

压缩感知的一种重构算法，此方法比OMP算法性能更好(Compression perception of a reconstruction algorithm, this method is better than the OMP algorithm performance)

其实popupwindow用起来比Dialog 方便，因为dialog一切都需要你自己来实现，而popupwindow帮我们实现了很多，我认为在使用的时候关键我们要看清参数： popupWindow.showAtLocation(parent, gravity, x, y) parent这个是一个父view试图， gravity 这个默认是居中，我们要指定显示方式：Gravity.LEFT | Gravity.TOP 最后两个参数就是显示的坐标位置，这样就可以根据需求自己定位显示位置了

时频分析方法提供了时间域与频率域的联合分布信息，清楚地描述了信号频率随时间变化的关系。(Time-frequency analysis method provides a time-domain and frequency domain, the joint distribution of information that clearly describes the signal frequency versus time relationships.)
