Keywords: Spaces of variable bandwidth, sign retrieval, phase retrieval

TL;DR: We prove that the variable band-width spaces of Gröchenig and Klotz are good candidates for phase retrieval as sign retrieval leads to unique solutions

Abstract:

The aim of this paper is to get a deeper understanding of the
spaces of variable bandwidth introduced by Gr\"ochenig and Klotz.
In particular, we show that when the variation of the bandwidth is modeled
by a step function with a finite number of jumps, then, the sign retrieval
principle applies.
