Necessary and sufficient conditions for the wave packet frames on positive half-line
(Işık University Press, 2016-04-22)
In this paper, we consider wave packet systems as special cases of generalized shift-invariant systems, a concept studied by Hern´andez, Lebate and Weiss. The objective of the paper is to construct wave packet frames on ...
A characterization of wave packet frames for L² (Rᵈ)
(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.
Matrix transform of irregular weyl-heisenberg wave packet frames for L² (R)
(Işık University Press, 2017)
Cordoba and Fefferman [4] 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 ...
