Transmit Beamforming for Interference Exploitation in the Underlay Cognitive Radio Z-channel
Ka Lung Law, Christos Masouros, Marius Pesavento
This paper introduces novel transmit beamforming approaches for the cognitive radio (CR) Z-channel. The proposed transmission schemes exploit non-causal information about the inter…
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…
