Filter-and-Forward Distributed Beamforming for Two-Way Relay Networks with Frequency Selective Channels
Abstract-- A new approach to distributed cooperative beamforming in two-way half-duplex relay networks with frequency selective channels is proposed. In our scheme, two transceiver...

Cooperative MIMO-beamforming for multiuser relay networks
In this paper, we develop a beamforming algorithm for multiuser MIMO-relaying wireless systems. We consider a relaying scenario with multiple sources transmitting to one or more d...

Distributed beamforming for multiuser peer-to-peer and multi-group multicasting relay networks
We generalize the concept of multiuser peer-to-peer (MUP2P) relay networks to that of a multi-group multicasting (MGM) relay network where each source may broadcast its message to...
