有较好的参考价值，构成不同频率的调制信号，预报误差法参数辨识-松弛的思想，数值分析的EULER法，使用高阶累积量对MPSK信号进行调制识别，这个有中文注释，看得明白，基于SVPWM的三电平逆变的matlab仿真。- There are good reference value, Constituting the modulated signals of different frequencies, Prediction Error Method for Parameter Identification- the idea of relaxation, EULER numerical analysis method, Using high-order cumulants of MPSK signal modulation recognition, The Chinese have a comment, understand it, Based on SVPWM three-level inverter matlab simulation.
