Consider a multi-user multi-cluster relay interference network where each cluster contains a
source-destination pair communicating through their own dedicated multi-antenna relays …

We consider a cellular network where each cell contains multiple source-destination pairs
communicating through multiple amplify-and-forward relays using orthogonal channels. We …

Beamforming is a powerful technique which has been widely used in signal processing,
radar and sonar, biomedical, and particularly in communications, where the basic idea is to …

In this paper, we study the optimal cooperative beamforming problem in the amplify-and-
forward (AF) multi-user and multi-relay networks, which face the challenges of rapid node …

We study the distributed optimal beamforming problem of a wireless amplify-and-forward
