摘要：

This paper focuses on the compressed sensing l(1) - l(2)-minimization model and develops new bounds on cumulative coherence mu(1) (s). It is pointed out that if cumulative coherence mu(1) (s) satisfies Equation (2) or (11), then the sparse signal can stably recover in noise model and exactly recover in free noise by l(1) - l(2)-minimization model.
