Wavelet Denoising of The Noise Elimination

摘要：

Most of the wavelet threshold denoising methods need to calculate the orresponding threshold. The estimation of noise variance will directly affect the effect of hreshold denoising method. This paper presents a new phase matching method of the noise variance estimation. The real-time current noise can be estimated by this method. The experiments show that the method can greatly improve the signal to noise ratio and can obtain better denoising effect.
