A new bound on the block restricted isometry constant in compressed sensing
This paper focuses on the sufficient condition of block sparse recovery with the [Formula: see text] -minimization. We show that if the measurement matrix satisfies the block restricted isometry property with [Formula: see text] , then every block s-sparse signal can be exactly recovered via the [Fo...
