Higher Order Spectra Denoising Method of Phase Matching Noise Estimation

Most denoising method can deal with Gaussian noise or some kind of colored noise. This paper presents a new method of higher order spectral denoising on phase matching noise estimation. The method can remove not only the Gaussian noise but also Non-Gaussian noise. The noise is removed by high order spectral and phase matching estimate of current noise. The experimental results clearly show that this method can remove the Gaussian and non-Gaussian noise. The method makes a good denoising when the noise can not be determined.
