| Abstract: | On the basis of the general discrete Zak transform and the relationships between the continuous and discrete Gabor expansions,we present a method to construct the discrete Gabor expansion via tight Weyl-Heisenberg frame in the case of oversampled by an integer factor. The properties of the constructed discrete Gabor expansions are also given. |
