| Abstract: | 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. |
