pwm整流器的建模仿真，抑制载波型差分相位调制，Matlab实现界面友好，采用偏最小二乘法，用于图像处理的独立分量分析，采用的是脉冲对消法，分析了该信号的时域、频域、倒谱，循环谱等,添加噪声处理。- Modeling and simulation pwm rectifier Suppressed carrier type differential phase modulation, Matlab to achieve user-friendly, Partial least squares method, Independent component analysis for image processing, It uses a pulse of consumer law, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. Add noise processing.
