Secrecy Enhancement of Multiuser MISO Networks Using OSTBC and Artificial Noise
In this paper, we propose a novel physical layer strategy to improve the secrecy performance of multiuser multiple-input single-output networks. In this strategy, orthogonal space-time block code (OSTBC) is employed at an AAantenna base station (BS) and artificial noise (AN) is employed at an AJ-antenna cooperative relay to enhance the security level of the network. Moreover, two opportunistic scheduling schemes, namely, selection combining (SC) and scan-and-wait combining (SWC), are...[Show more]
