Nonuniform sampling and recovery of multidimensional bandlimited functions by Gaussian radial-basis functions

A. Bailey, Th. Schlumprecht, N. Sivakumar

Let $S \subset R^{d}$ be a bounded subset with positive Lebesgue measure. The Paley-Wiener space associated to $S$ , $P W_{S}$ , is defined to be the set of all square-integrable functions…

On the sampling and recovery of bandlimited functions via scattered translates of the Gaussian

Th. Schlumprecht, N. Sivakumar

Let $λ$ be a positive number, and let $(x_{j} : j \in Z) \subset R$ be a fixed Riesz-basis sequence, namely, $(x_{j})$ is strictly increasing, and the set of functions $\{\ma…
