Distributed Beamforming and Power Allocation for Cooperative Networks [PDF]
IEEE Transactions on Wireless Communications, 2008 Cooperative diversity systems rely on using relay nodes to relay copies of transmitted information to the destination such that each copy experiences different channel fading, hence increasing the diversity of the system. However, without proper processing of the message at the relays, the performance of the cooperative system may not necessarily ...

Transmit Beamforming in Cooperative Networks
VTC Spring 2008 - IEEE Vehicular Technology Conference, 2008Cooperative relay communication systems has been extensively studied in recent years due to their ability to provide more reliable communications through enhanced diversity and to extend the range of the communication system. Equipping communication terminals with multiple antennas have similar advantages.

Cognitive beamforming with cooperative feedback
2010 International Conference on Wireless Communications & Signal Processing (WCSP), 2010In cognitive radio networks based on spectrum sharing, cognitive beamforming (CB) enables the multi-antenna secondary user (SU) transmitter to suppress the interference to the primary user (PU) receiver and yet maximize the SU link throughput. In our prior work, a design framework was proposed for realizing CB based on finite-rate cooperative feedback ...

IEEE Journal on Selected Areas in Communications, 2018 International audienceIn this paper, we consider a scenario where the satellite-terrestrial network is overlaid over the legacy cellular network. The established communication system is operated in the millimeter wave (mmWave) frequencies, which enables ...

A distributed algorithm for cooperative relay beamforming
2013 American Control Conference, 2013We consider the problem of cooperative beamforming in relay networks. Assuming knowledge of the second-order statistics of channel state information (CSI), the optimal beamforming weights are determined so that the total transmitted power at the relays is minimized, while meeting signal-to-interference-plus-noise-ratio (SINR) requirements at the ...

Virtual Cell Beamforming in Cooperative Networks
IEEE Journal on Selected Areas in Communications, 2014We study the coordinated transmission problem in cooperative cellular networks where a cluster of base stations forms a virtual cell to serve a mobile station (MS). The performance of such an MS-centric virtual cell network is dictated by the beamformer that enables to suppress interference; however, designing a beamformer is highly challenging due to ...

Cooperative Beamforming Exploiting Energy Recycling
2018 25th International Conference on Telecommunications (ICT), 2018We propose and investigate a communications scheme for exploiting multiple Amplify and Forward (AF) relays using the principle of energy recycling. For this scheme, we consider concurrent use of the multiple relays, and study the problem of rate-optimal beamformer design, presenting a new algorithmic solution.
