Distributed Cooperative Beamforming in Multi-Source Multi-Destination Clustered Systems

We consider the scenario of a multi-cluster network, in which each cluster contains multiple single-antenna source destination pairs that communicate simultaneously over the same channel. The communications are supported by cooperating amplify-and-forward relays, which perform beamforming. While the communications take place within the cluster, there is inter-cluster as well as intra-cluster interference. The beamforming weights are obtained so...
