Prony's Method in Banach Modules

Functional Analysis 2024-03-29 v1 Spectral Theory

Abstract

We show that the classical Prony's method for recovery of a sparse signal from its consecutive Fourier coefficients can be viewed as a spectral identification problem for an unknown restriction of a known linear operator. This presents a unified point of view on various existing and novel generalizations and applications of the method, some of which are discussed in this paper.
