Network beamforming in cognitive relay networks with QoS constraints
2011 IFIP Wireless Days (WD), 2011In this paper, we propose a distributed relay beam-forming design in an underlay based cognitive relay network. In the proposed approach, beamforming coefficients of the secondary relays are obtained through minimization of the peak interference power inflicted on the primary receiver subject to the signal to noise-interference ratio (SINR) constraint ...

Optimal network beamforming for bi-directional relay networks
2009 IEEE International Conference on Acoustics, Speech and Signal Processing, 2009We consider a relay network which consists of two transceivers and r relay nodes. We study a half-duplex two-way relaying scheme. First, the two transceivers transmit their information symbols simultaneously and the relays receive a noisy mixture of the two transceiver signals.

Network Duality for Multiuser MIMO Beamforming Networks and Applications
IEEE Transactions on Communications, 2007For any multiple-input multiple-output (MIMO) network with linear beamformers, it is shown that there exists a dual network that attains the same signal-to-interference-plus-noise ratio (SINR) performance. This network duality concept is a generalization of the virtual uplink concept investigated by Rashid-Farrokhi .

Doubly Opportunistic Beamforming for Finite Networks
2016 IEEE Global Communications Conference (GLOBECOM), 2016We develop a novel opportunistic beamforming scheme referred to as doubly opportunistic beamforming (DOBF), which is doubly selective in both users and beams. The sum-rate performance of the proposed scheme is investigated in less-known finite networks where the number of transmit antennas and the number of active users are finite and of the same order
