Phase retrieval (Phaseless sampling and reconstruction) plays important roles in signal/image/speech processing. It consists of reconstructing a signal of interest from its magnitude measurements. The underlying recovery problem is possible to solve only if we have additional information about the signal. In this talk, we consider phaseless sampling and reconstruction of real-valued signals in a shift-invariant space from their magnitude measurements on the Euclidean space and from their phaseless samples taken on a discrete set with finite sampling density.
