Signals on Graphs: Uncertainty Principle and Sampling
TL;DR: An uncertainty principle for graph signals is derived and the conditions for the recovery of band-limited signals from a subset of samples are illustrated and shown, showing an interesting link between uncertainty principle and sampling and proposing alternative signal recovery algorithms.
Proceedings ArticleDOI
An introduction to hypergraph signal processing
TL;DR: This paper suggests alternative ways to introduce a Fourier Transform for signals defined over hypergraphs and, in particular, for simplicial complexes and derives a sampling theorem aimed at identifying the minimum number of samples necessary to encode all information about band-limited hypergraph signals.
Proceedings ArticleDOI
On the degrees of freedom of signals on graphs
TL;DR: The conditions for perfect reconstruction of a graph signal from its samples are provided and the effect of sampling a non perfectly band-limited signal and how to select the bandwidth that minimizes the mean square reconstruction error are shown.
Proceedings ArticleDOI
Uncertainty principle and sampling of signals defined on graphs
TL;DR: In this paper, the authors provide an uncertainty principle for signals on graphs and establish a direct relation between uncertainty principle and sampling, which forms the basis for a sampling theorem of signals defined on graphs.
