说明：  matlab 做的仿真 SPWM 单相 全桥逆变(Matlab do simulation SPWM inverter single-phase bridge)

参数为：载波频率f0为20MHz，采样频率为4倍f0，脉宽为1us ，脉冲周期为20us 。其中：(Parameters: carrier frequency f0 is 20MHz, the sampling frequency is 4 times f0, a pulse width of 1us, the pulse period is 20us. Of which:)

CPM的一种相干解调，程序内容较为丰富，基本的函数都有。希望有用。(CPM of a coherent demodulation, the program more inclusive, have the basic function. Hope helpful.)

REAL TIME MODELING BY USING DSPACE

OFDM multipath fading channel model jakes

核主成分分析算法KPCA 的matlab程序/代码 基于二维数据的。(kernel principal component analysis)

采用带宽为3，中心频率为3的复morlet小波对示例信号进行了分析，并绘出时频图。(Using bandwidth of 3, center frequency is 3 complex morlet wavelet to sample signal is analyzed, and draw the time-frequency diagrams.)

说明：  MATLAB下生成hilbert矩阵,直接输入一个大于零的参数,就可以生成该矩阵(MATLAB generated hilbert matrix, directly into a parameter greater than zero, we can generate the matrix)

用于人脸识别的PCAKNN算法，算法可成功运行。(a useful program, )
