Network Beamforming Using Relays With Perfect Channel Information
Network Beamforming Using Relays With Perfect Channel Information
This paper deals with beamforming in wireless relay networks with perfect channel information at the relays, receiver, and transmitter if there is a direct link between the transmitter and receiver. It is assumed that every node in the network has its own power constraint. A two-step amplify-and-forward protocol is used, …
