New conditions for uniformly recovering sparse signals via orthogonal matching pursuit
We define a new measure, called union cumulative coherence, for the measurement matrix. We present a new condition for uniformly recovering sparse signals via OMP. The relation of the proposed condition with the existing ones is studied. Sparse recovery from noisy measurements in terms of union cumulative coherence is also addressed.
