A Sharp RIP Condition for Orthogonal Matching Pursuit
A restricted isometry property (RIP) condition δK+KθK,1<1 is known to be sufficient for orthogonal matching pursuit (OMP) to exactly recover every K-sparse signal x from measurements y=Φx. This paper is devoted to demonstrate that this condition is sharp. We construct a specific matrix with δK+Kθ...
