Signal Recovery on Graphs: Fundamental Limits of Sampling Strategies
Siheng Chen, Rohan Varma, Aarti Singh +1
This paper builds theoretical foundations for the recovery of a newly proposed class of smooth graph signals, approximately bandlimited graph signals, under three sampling strategi…
Signal Recovery on Graphs: Random versus Experimentally Designed Sampling
Siheng Chen, Rohan Varma, Aarti Singh +1
We study signal recovery on graphs based on two sampling strategies: random sampling and experimentally designed sampling. We propose a new class of smooth graph signals, called ap…
Discrete Signal Processing on Graphs: Sampling Theory
Siheng Chen, Rohan Varma, Aliaksei Sandryhaila +1
We propose a sampling theory for signals that are supported on either directed or undirected graphs. The theory follows the same paradigm as classical sampling theory. We show that…
