Beamforming in Wireless Relay Networks

by Yindi Jing, Hamid Jafarkhani
"... This paper is on relay beamforming in wireless networks, in which the receiver has perfect information of all channels and each relay knows its own channels. Instead of the commonly used total power constraint on relays and the transmitter, we use a more practical assumption that every node in the ..."

Trans-modulation in wireless relay networks

by Karim G. Seddik, Ahmed S. Ibrahim, K. J. Ray Liu - IEEE Communications Letters , 2008
"... Abstract — In this letter, we consider the trans-modulation design for the decode-and-forward relay networks. We propose to reassign the constellation points at the relay nodes to minimize the symbol error rate (SER) at the destination node. The proposed trans-modulation scheme can significantly imp ..."

On the throughput scaling of wireless relay networks

by Massimo Franceschetti, Patrick Thiran - IEEE Trans. Information Theory , 2006
"... Abstract—The throughput of wireless networks is known to scale poorly when the number of users grows. The rate at which an arbitrary pair of nodes can communicate must decrease to zero as the number of users tends to infinity, under various assumptions. One of them is the requirement that the networ ..."

Distributed space-time coding in wireless relay networks,”IEEE Trans.

by Frédérique Oggier , Babak Hassibi - on Wireless Communications, , 2006
"... Abstract In this paper, we present a coding strategy for half duplex wireless relay networks, where we assume no channel knowledge at any of the transmitter, receiver or relays. The coding scheme uses distributed space-time coding, that is, the relay nodes cooperate to encode the transmitted signal ..."

On the Optimal Design of Wireless Relay Networks

by Vahid Pourahmadi, Shervan Fashandi, Aladdin Saleh, Amir K. Khandani
"... It is known that the achievable data rate per user can be increased when relays are deployed in wireless networks. However, the drawback of this solution is that some of the network resources should be allocated to the relays. In this paper, we consider a two-tier network where all users should send ..."

Distributed Beamforming in Wireless Relay Networks

by Siavash Fazeli-dehkordy , 2008
"... In this thesis, we consider a wireless network consisting of d source-destination pairs and R relaying nodes. Each source wishes to communicate to its corresponding desti-nation. By exploiting the spatial multiplexing capability of the wireless medium, we develop two cooperative beamforming schemes ..."
