The authors give new sufficient conditions under which shift-invariant systems become frames for \(L^2(\mathbb{R}^n).\) Also, under these conditions, it is shown that the frames obtained have better frame bounds than those previously obtained for such shift-invariant systems. As an application, the results directly give frames from Gabor systems.
