摘要

The wavelet Shrinkage is one of the nonlinear signal denoising method to remove Speckle noise by shrinking the empirical wavelet coefficients in the wavelet domain. In this paper, we propose the adaptive wavelet shrinkage which updates the threshold levels adaptively by Least Mean Square (LMS) type algorithm according to the reference signal. The adaptive wavelet Shrinkage Method is robust and it is also easy to control the filter action by modifying the threshold levels directly.
