Paper Abstract

The null space property (NSP) and the restricted isometry property (RIP) are two properties which have received considerable attention in the compressed sensing literature. It is known that the null space property guarantees a less than ideal stability result. In this paper, we show that this bound is actually tight by specific construction, which implies a fundamental difference between NSP and RIP.
