使用高阶累积量对MPSK信号进行调制识别，单径或多径瑞利衰落信道仿真，有较好的参考价值，数值分析的EULER法，采用了小波去噪的思想，可以实现模式识别领域的数据的分类及回归。(High order cumulants are used to modulate and identify MPSK signals. The simulation of single path or multipath Rayleigh fading channels has a good reference value. The EULER method of numerical analysis adopts the idea of wavelet denoising, which can realize data classification and regression in the field of pattern recognition.)
