WebFeb 15, 2024 · The incoherence and isotropy properties together guarantee that sparse vectors lie away from the nullspace of the sensing matrix. The role of the isotropy condition is to keep the measurement matrix from being rank deficient when sufficiently many measurements are taken. Webwhen facing unsatisfactory mutual incoherence properties (MIPs) [20], [26] has also been ignored in the current literature. For the joint block-sparse signal recovery, a fundamental issue is to analyze the recoverability of the algorithms.

WebJun 3, 2024 · Incoherence: This is the property of the sensing matrix A that aids to determine the recovery ability of A (Joel, 2003) (David & Michael, 2002). It is specifically used to determine the sufficient condition for L 0 and L 1 unique solutions (Heung-No, 2011 - Introduction to compressive sensing: With coding theory perspective ). WebAug 1, 2011 · We prove that if the probability distribution F obeys a simple incoherence property and an isotropy property, one can faithfully recover approximately sparse signals from a minimal number of noisy measurements. The novelty is that our recovery results do not require the restricted isometry property (RIP) to hold near the sparsity level in ...
