Abstract

The null space condition is a condition under which k-sparse signal can be recovered uniquely in compressed sensing (CS) problems. In this paper, new efficient algorithms are introduced to verify the null space condition for l1 minimization in compressed sensing. Suppose A is an (n - m) × n (m > 0) sensing matrix, we can verify whether the sensing matrix A satisfies the null space condition or not for k-sparse signals by computing αk = |zK|1/|z
