Shift-Invariant Spaces, Bandlimited Spaces and Reproducing Kernel Spaces With Shift-Invariant Kernels on Undirected Finite Graphs
In this paper, we introduce the concept of graph shift-invariant spaces (GSISs) of graph signals on undirected finite graphs and investigate their bandlimiting, reproducing kernel, and sampling properties. Bandlimited spaces are the most widely adopted models for representing graph signals. In this paper, under some te...
