一种改进的小波阈值信号去噪方法

Abstract

Abstract:

In order to improve the filtering effect and the quality of denoising,this paper proposes a new denoising method for wavelet threshold signal processing.The method combines the characteristics of soft and hard threshold and optimizes the parameters for better threshold estimation.Through Matlab simulation,the proposed algorithm is compared with the traditional wavelet threshold,which shows that the proposed algorithm had better denoising effect and stability.

Key words: wavelet denoising threshold;threshold function;SNR;mean square error
