中文说明：仿真效果非常好，单径或多径瑞利衰落信道仿真，是小学期课程设计的题目，分析了该信号的时域、频域、倒谱，循环谱等,基于互功率谱的时延估计，预报误差法参数辨识-松弛的思想。
English Description：
Simulation results is very good, single path or multipath Rayleigh fading channel simulation, is the title of primary phase of the course design, analyzes the the signal in time domain and frequency domain, cepstrum, cyclic spectrum, based on the cross power spectrum of the time delay estimation and prediction error method for parameter identification and relaxation.
