Obstructions for Gabor frames of the second order B-spline

Riya Ghosh, A. Antony Selvan

For a window $g \in L^{2} (R)$ , the subset of all lattice parameters $(a, b) \in R_{+}^{2}$ such that $\mathcal{G}(g,a,b)=\{e^{2πib m\cdot}g(\cdot-a k) : k, m\in\mathbb{Z}…

On Gabor frames generated by B-splines, totally positive functions, and Hermite functions

Riya Ghosh, A. Antony Selvan

The frame set of a window $ϕ \in L^{2} (R)$ is the subset of all lattice parameters $(α, β) \in R_{+}^{2}$ such that $\mathcal{G}(ϕ,α,β)=\{e^{2πiβm\cdot}ϕ(\cdot-αk) : k, m…
