中文说明：最小均方误差（MMSE）的算法，最大似然（ML）准则和最大后验概率（MAP）准则，采用了小波去噪的思想，分析了该信号的时域、频域、倒谱，循环谱等,是本科毕设的题目，可以得到很精确的幅值、频率、相位估计。
English Description：
Minimum mean square error (MMSE) algorithm, maximum likelihood (ML) criterion and maximum posterior probability (map) criterion, the wavelet denoising of thought, analyzes the the signal in time domain and frequency domain, cepstrum, cyclic spectrum, undergraduate graduation design topic, can get very accurate amplitude value, frequency and phase estimation.
