Abstract

We obtain a structured class of frames in separable Hilbert spaces which are generalizations of Gabor frames in L2(ℝ) in their construction aspects. For this, the concept of Gabor type unitary systems in [13] is generalized by considering a system of invertible operators in place of unitary systems. Pseudo Gabor like frames and pseudo Gabor frames are introduced and the corresponding frame operators are characterized.
