This paper investigates the problem of designing a deterministic system matrix, that is measurement matrix, for sparse recovery. An efficient greedy algorithm is proposed in order to extract the class of sparse signal/image which cannot be reconstructed by l1-minimization for a fixed system matrix. Based on the polytope theory, the algorithm provides a… (More)
