ofdma的一个简单的收发程序采用QPSK调制噪声是高斯白噪声(A simple transceiver of ofdma program using QPSK modulation noise is gaussian white noise)

基于电网电压定向的逆变器并网simulnk图，正确的可以运行。(Based on the orientation of the grid voltage inverter grid simulnk map, you can run correctly.)

EMD或者LMD的能量密度与其平均周期的乘积K值，当K值发生较大变化的时候，证实该分量为白噪声，可以剔除，将剩下的分量进行重构，达到去噪的目的。(The product of K EMD or LMD energy density and average cycle value when the K value was changed greatly, the component for white noise can be eliminated, the remaining components are reconstructed to achieve the purpose of de-noising.)

隔离型单端反激型直直变换器的Matlab/simulink仿真例程，已检测运行无误。(Isolated single-ended flyback straight converter Matlab/Simulink simulation routines, has been detected running correctly.)
