Exploiting Direct Links for Physical Layer Security in Multi-user Multi-relay Networks

Fan, Lisheng; Yang, Nan; Duong, Trung Q.; Elkashlan, Maged; Karagiannidis, George K.


We present two physical layer secure transmission schemes for multi-user multi-relay networks, where the communication from M users to the base station is assisted by direct links and by N decode-and-forward relays. In this network, we consider that a passive eavesdropper exists to overhear the transmitted information, which entails exploiting the advantages of both direct and relay links for physical layer security enhancement. To fulfill this requirement, we investigate two criteria...[Show more]
