Abstract

In this paper Wilson frame as a generalization of Wilson baseshas been defined.A sufficent condition for a Wilson system to be a WilsonBessel sequence in terms of a Gabor Bessel sequence has been given. Itis shown that the canonical dual frame of a Wilson frame may not have aWilson structure.Also,a sufficient condition for two Wilson Bessel sequencesto be dual frames has been given in terms of dual Gabor frames.
