Li, Lan Perturbation of Gabor frame and dual of Gabor frame. (Chinese. English summary) Zbl 1174.42343 Basic Sci. J. Text. Univ. 21, No. 1, 61-63 (2008). Summary: The dual of Gabor frame’s structure is discussed, and then explicit structure of the dual of Gabor frame is given. Under the small perturbation of \(\varphi\), some changes take place about the dual of Gabor frame. Stability of the dual of Gabor frame is proved under the weak conditions.
