Random space-time sampling and reconstruction of sparse bandlimited graph diffusion field
Longxiu Huang, Dongyang Li, Sui Tang +1
In this work, we investigate the sampling and reconstruction of spectrally -sparse bandlimited graph signals governed by heat diffusion processes. We propose a random space-time…
