چکیده
|
The duals of gabor frames have an essential role in reconstruction of signals. in this paper we find a necessary and sufficient condition for two gabor systems (x[c1,d1),a,b) and (x[c2,d2),a,b) to form dual frames for l_2(r), where a and b are positive numbers and c1,c2,d1 and d2 are real numbers such that c1 < d1 and c2 < d2.
