Title: Characterization of Distributed Compressive Sensing with Signal Diversity

Abstract:

Distributed Compressive Sensing (DCS) exploits joint sparsity in signal ensembles represented by multiple measurement vectors (MMVs). Nevertheless, current theoretical guarantees for perfect recovery in the MMV setting remain largely comparable to those of the single measurement vector (SMV) case.

In this talk, I examine how intrinsic properties of signal ensembles affect recovery performance in a deterministic MMV framework. In particular, I focus on two key factors: the Euclidean distance between signals and the decay behavior of their coefficients.
