Abstract:

In digital signal and image processing one can only process discrete signals of finite length, and the space C-L is the preferred setting. Recently, Kutyniok and Strohmer constructed orthonormal Wilson bases for C-L with general lattices of volume L/2 ( L even). In this paper, we extend this construction to Wilson frames for C-L with general lattices of volume L/2K, where K is an element of N and L is an element of 2KN. We obtain a necessary and sufficient condition for two sequences having Wilson structure to be dual frames for C-L. When the window function satisfies some symmetry property, we obtain a characterization of a Wilson system to be a tight frame for C-L, show that a Wilson frame for C-L can be derived from the underlying Gabor frame, and that the dual frame having Wilson structure can also be derived from the canonical Gabor dual of the underlying Gabor frame.
