Stable phase retrieval from short-time linear canonical transforms of signals in Gaussian shift-invariant spaces
Cheng Cheng, Baixiang Wu, Jun Xian
Gabor phase retrieval for signals has attracted considerable attention in recent years. For the more general short-time linear canonical transform (STLCT), which arises naturally i…

Conjugate phase retrieval on graphs and with applications in shift-invariant spaces
Cheng Cheng, Baixiang Wu, Jun Xian
In this paper, we study the conjugate phase retrieval for complex-valued \mbox{signals} residing on graphs, and explore its applications to shift-invariant spaces. Given a complex-…
