In the context of compressed sensing, the nonconvex minimization with has been studied in recent years. In this letter, by generalizing the sharp bound for minimization of Cai and Zhang, we show that the condition in terms of restricted isometry constant (RIC) can guarantee the exact recovery of -sparse signals...
Binary 0–1 measurement matrices, especially those from coding theory, were introduced to compressed sensing (CS) recently. Good measurement matrices with preferred properties, e.g., the restricted isometry property (RIP) and nullspace property (NSP), have no known general ways to be efficiently checked. Khajehnejad et al. made use of girth to certify the good performances of sparse binary measurement...
In this paper, we study the maximum multicast set scheduling problem in a plane wireless network under the physical interference model. Specifically, from a given set of multicast transmissions, select a maximum set of multicast transmissions with largest sum of receivers, where each receiver of a multicast transmission is interference-free from other transmissions subject to the physical interference...
