Abstract

This paper extends the efficient factorization of the Gabor frame operator developed by Strohmer (1998) to the Gabor analysis/synthesis operator. This provides a fast method for computing the discrete Gabor transform (DGT) and several algorithms associated with it. The algorithm is used for the case when the involved window and signal have the same length.
