摘要：
Duality principles in Gabor frame theory have a key roll in applications. Each dual frame enable us to write every element in the underlying Hilbert space as a linear combination of the frame elements. Canonical dual is used usually in this construction. In this article, it is proved that by using alternate duals we obtain more accurate results. (C) 2013 Elsevier Inc. All rights reserved.
