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…

Kalman Filtering of Stationary Graph Signals
Yang Chen, Yeonju Lee, Yao Shi +1
In this paper, we propose a novel definition of stationary graph signals, formulated with respect to a symmetric graph shift, such as the graph Laplacian. We show that stationary g…

Blind Deconvolution of Nonstationary Graph Signals over Shift-Invariant Channels
Ali Zare, Yao Shi, Qiyu Sun
In this paper, we investigate blind deconvolution of nonstationary graph signals from noisy observations, transmitted through an unknown shift-invariant channel. The deconvolution…
