Sah, Ashok Kumar (Işık University Press, 2018)In this paper we present necessary and sufficient conditions with explicit frame bounds for a finite sum of wave packet frames to be a frame for L²(Rᵈ). Further, we illustrate our results with some examples and applications.
Cordoba and Fefferman  introduced wave packet systems by applying certain collections of dilations, modulations and translations to the Gaussian function in the study of some classes of singular integral operators. In ...
