We investigate selection beamforming for a cooperative network that consists of a source, a destination, and two amplify-and-forward (AF) relays, which are all equipped with multiple antennas. The transmit and receive beamforming techniques are respectively applied at the source and destination, and the linear processing operator of the selected AF multiple-input multiple-output (MIMO) relay is optimized...
It has been shown that, in multi-source multi-relay networks, the use of network coding that utilizes cooperation among intra-cluster nodes can improve the outage performance. When each node is equipped with a single antenna, the relay-destination link will become the bottleneck that limits the overall network diversity gain. In this paper, we propose the use of multiple antennas at the destination...
