摘　　要：高阶统计量是信号处理的一种新的强有力的工具，近年来在谐波恢复领域取得了很好的应用效果。文中综述了基于高阶统计量的谐波恢复方法以及基于各阶统计量相混合的预滤波谐波恢复方法。表明高阶统计量方法可以有效地抑制有色噪声的影响。Recently,higher order statistics has become a new powerful tool in the field of signal processing and is effective in the application to harmonic retrieval of noise.This paper summarizes the newly developed higher order statistics based approaches and prefiltering based methods with hybrid higher order statistic for estimating the parameters of harmonics in noise.It is shown that the higher order statistics approaches restrain effectively the effect of coloured noise.
