Apply Artificial Noise To Secure Fading Relay Networks: A SER-Based Approach
Ying Liu, Liang Li, George C. Alexandropoulos +1
We apply the concept of artificial and controlled interference in a triangular relay network with an untrusted relay aiming at enhancing the wireless communication secrecy between…
Rank-Two Beamforming and Power Allocation in Multicasting Relay Networks
Adrian Schad, Ka L. Law, Marius Pesavento
In this paper, we propose a novel single-group multicasting relay beamforming scheme. We assume a source that transmits common messages via multiple amplify-and-forward relays to m…
General Rank Multiuser Downlink Beamforming With Shaping Constraints Using Real-valued OSTBC
Ka Lung Law, Xin Wen, Minh Thanh Vu +1
In this paper we consider optimal multiuser downlink beamforming in the presence of a massive number of arbitrary quadratic shaping constraints. We combine beamforming with full-ra…
