摘要
Abstract
Experiments show that GBCD has good performance when the point sources are intensive ,or the number of snapshots is small ,but the function of GBCD under the interfere of noise is not illustrated .In this paper ,when ‖ E ‖ 2 尘 ε , if the sensing matrix A satisfies the RIP with δK + 1 < 1K + 1 ,then the GBCD can exactly recover the support of X in K itera‐tions ,under the constraint on the minimum magnitude of the nonzero elements of X .关键词
