说明：  针对EMD方法的不足,单径或多径瑞利衰落信道仿真，主要是基于mtlab的程序，包括数据分析、绘图等等,FMCW调频连续波雷达的测距测角，鲁棒性好，性能优越，基于人工神经网络的常用数字信号调制。
( For lack of EMD, Single path or multipath Rayleigh fading channel simulation, Mainly based on the mtlab procedures, Data analysis, plotting, etc., FMCW frequency modulated continuous wave radar range and angular measurements, Robustness, superior performance, The commonly used digital signal modulation based on artificial neural network.)
