Abstract

We consider a class of Gabor-type matrices and develop simplified Gabor-type matrix operations. As applications to discrete Gabor transforms, we propose `superfast' algorithms for determining the inverse of Gabor frame operators and the square roots of the Gabor frame operators as well as the dual Gabor and tight Gabor atoms. Besides, we summarize briefly some additional results.
