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…

Convolutional dynamical sampling and some new results
Longxiu Huang, A. Martina Neuman, Sui Tang +1
In this work, we explore the dynamical sampling problem on driven by a convolution operator defined by a convolution kernel. This problem is inspired by the ne…
