COMPANDING USING ULAW IN MIMOOFDM

Wigner-Ville 分布(简称 WVD)是典型的二次型变换，它定义为信号瞬时相关函数的傅立 叶变换。 由于在计算中不加窗操作，它避免了时域分辨率和频域分辨率之间的相互牵制。 已证明，对于单分量线性调频信号，WVD 的时频表示能量集中性最优。但也正因为不涉 及窗函数，在分析多分量信号时 WVD 会受到交叉项的干扰。(The Wigner-Ville distribution (WVD) is a typical quadratic transformation, which is defined as the Fourier of the instantaneous correlation function of a signal. Ye Bianhuan. Because of no window operation in the calculation, it avoids the mutual restraint between time domain resolution and frequency domain resolution. It has been proved that for the single component LFM signal, the WVD time frequency representation has the best energy concentration. But it is also because it does not involve. And window functions, when WVD is used to analyze multi-component signals, it will be interfered by cross terms.)

说明：  单相桥式整流电路闭环相控调压，simulink中搭建单相桥式整流电路，利用PI控制方式，实现输出电压的相控(The single-phase bridge rectifier circuit is closed-loop phase controlled voltage regulation, the single-phase bridge rectifier circuit is built in Simulink, and the PI control mode is used to realize the phase control of output voltage)

关于matlab的方法及实例，有效，全面，是数学建模的好帮手(about matlab)

第5个：matlab 和C++联合用于SVM，另外一种风格的(the 5 file: matlab and c++ together for SVM)

经验模态法可以做信号加强、模式识别、特征提取等,本程序是经验模态的matlab实现，(the realization of emd using matlab.it canbe used in the signal denoising ,pattern recognition and feature extraction )
