Further discussions on adaptive filters to improve the wavelet shrinkage method

Abstract

We earlier proposed a novel on-line denoising structure which utilized the adaptive filter to improve the wavelet shrinkage and did acquire some positive results. In this paper, we will have a further discussion based on this structure. Topics include parameter adjustments, LMS non-causal cases, the decision of both DWT level and mother wavelet, and RLS algorithm. Based on these discussions, we will be able to fine tune our denoising structure and come up with better results.
