On The Exact Recovery Condition of Simultaneous Orthogonal Matching Pursuit
Jean-François Determe, Jérôme Louveaux, Laurent Jacques +1
Several exact recovery criteria (ERC) ensuring that orthogonal matching pursuit (OMP) identifies the correct support of sparse signals have been developed in the last few years. Th…
Consistent Basis Pursuit for Signal and Matrix Estimates in Quantized Compressed Sensing
Amirafshar Moshtaghpour, Laurent Jacques, Valerio Cambareri +2
This paper focuses on the estimation of low-complexity signals when they are observed through uniformly quantized compressive observations. Among such signals, we consider 1-D…
Simultaneous Orthogonal Matching Pursuit With Noise Stabilization: Theoretical Analysis
J. F. Determe, J. Louveaux, L. Jacques +1
This paper studies the joint support recovery of similar sparse vectors on the basis of a limited number of noisy linear measurements, i.e., in a multiple measurement vector (MMV)…
Small Width, Low Distortions: Quantized Random Embeddings of Low-complexity Sets
Laurent Jacques
Under which conditions and with which distortions can we preserve the pairwise-distances of low-complexity vectors, e.g., for structured sets such as the set of sparse vectors or t…
