Some New Results About Sufficient Conditions for Exact Support Recovery of Sparse Signals via Orthogonal Matching Pursuit

Support recovery of sparse signals via orthogonal matching pursuit (OMP) has been extensively studied in recent years. In this paper, by exploiting the knowledge about orthogonal projection matrix and Schur complement, we study the sufficient conditions for exact support recovery of sparse signals w...
