Li, Deng Feng et Qian, Tao, Sufficient conditions for shift-invariant systems to be frames in L 2(.n), Acta mathematica Sinica. English series (Print) , 29(8), 2013, pp. 1629-1636
The main purpose of this paper is to establish some new sufficient conditions under which shift-invariant systems become frames in L 2(.n). As applications, we obtain new results for Gabor frames.
