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-…

Random Sampling of Bandlimited Graph Signals from Local Measurements
Lili Shen, Jun Xian, Cheng Cheng
The random sampling on graph signals is one of the fundamental topics in graph signal processing. In this letter, we consider the random sampling of k-bandlimited signals from the…
