A Characterization of Subspace MRA Wavelets
Chen Xu-li · Journal of Shantou University · 2011
In this paper,the concepts of wavelet,MRA and MRA wavelet are introduced.According to some known theorems,the relation between a wavelet and a MRA wavelet is studied. The conditions that MRA wavelet and MRA wavelet set exist are studied. Based on above methods,a necessary and sufficient condition for MRA wavelet is obtained.
