It is then proved that if there are enough samples relative to the rank of Y and its incoherence property, then Alg1(Tr) retrieves the matrix Y exactly with high probability, assuming the samples are chosen uniformly at WebCompressive Sensing - Incoherence Property Ask Question Asked 9 years, 2 months ago Modified 3 years, 9 months ago Viewed 5k times 4 Compressive Sensing is built on 2 …
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 ...
