中文说明：最大似然（ML）准则和最大后验概率（MAP）准则，可以得到很精确的幅值、频率、相位估计，采用累计贡献率的方法，添加噪声处理，代码里有很完整的注释和解释，仿真效果非常好。
English Description：
Criterion of maximum likelihood (ML) and maximum a posteriori (map) criterion can be very accurate amplitude, frequency and phase estimation is obtained. The accumulative contribution rate method, add noise to deal with, the code is very complete annotated and explained, simulation effect is very good.
