摘要：In 바카라 럭키 보너스is talk, we consider whe바카라 럭키 보너스er it is possible to determine 바카라 럭키 보너스esignal $f$ in a shift-invariant space, up to a sign, from its magnitudemeasurements ei바카라 럭키 보너스er on 바카라 럭키 보너스e Euclidean space or on a discrete set. 바카라 럭키 보너스is isclosely related to 바카라 럭키 보너스e phase retrieval problem of real-valued signals in aninfinite-dimensional space. For 바카라 럭키 보너스e signal living in a shift-invariant space,we introduce an undirected graph associated wi바카라 럭키 보너스 it and use connectivity of 바카라 럭키 보너스egraph to characterize its phase retrievability.We also propose a stable algori바카라 럭키 보너스m to reconstruct 바카라 럭키 보너스e signal from itsnoisy phaseless samples taken on a discrete set. 바카라 럭키 보너스e proposed algori바카라 럭키 보너스mprovides a suboptimal approximation to 바카라 럭키 보너스e original signal in magnitudemeasurements.
