Abstract :
In this paper, Gabor frame, which is generated by multiple generators of L2(Rd), is studied. Firstly, several sufficient conditions and necessary conditions are presented for multi-Gabor frame (MGF). Then, these results are extended to the matrices which satisfy A = (BT)-1, and two corollaries are given for Gabor frame {EmBTnAgl: m, n ϵ Zd; l = 1, ..., L}. Finally, an example is provided for illustration.
