Sparse Recovery with Orthogonal Matching Pursuit under RIP

Web21. apr 2015. · Orthogonal Matching Pursuit Algorithm (OMP) is a greedy compressed sensing recovery algorithm which selects the best fitting column of the sensing matrix in each iteration. A least squares (LS) optimization is then performed in the subspace spanned by all previously picked columns. This method is less accurate than the Basis pursuit … WebIf i ∈ supp (α), then OMP fails to recover β. If i ∈ supp (β), then OMP fails to recover α. Hence, OMP either cannot recover α or cannot recover β in q / 2 iterations. • We consider to recover α by solving BP.
