Conjugate phase retrieval in shift-invariant spaces generated by a Gaussian
Yang Chen, Cheng Cheng
Conjugate phase retrieval considers the recovery of a function, up to a unimodular constant and conjugation, from its phaseless measurements. In this paper, we explore the conjugat…

Shift-invariant spaces on finite undirected graphs
Yang Chen, Seok-Young Chung, Qiyu Sun
Shift-invariant spaces (SISs) on the real line provide a natural framework for representing, analyzing and processing signals with inherent shift-invariant structure. In this paper…
