Abstract

This paper deals with the convergence of the wavelet thresholding estimator on Besov spaces \(B_{p,q}^s(\mathbb{R}^n)\). We show firstly the equivalence of several Besov norms. It seems different with one dimensional case. Then we provide two convergence theorems for the wavelet thresholding estimator, which extend Liu and Wang's work [Y.-M. Liu, H.-Y. Wang, Appl. Comput. Harmon. Anal., \({\bf 32}\) (2012), 342--356].
