Bidirectional multi-pair network with a MIMO relay: Beamforming strategies and lack of duality
Bidirectional multi-pair network with a MIMO relay: Beamforming strategies and lack of duality
We address the problem of a multi-user relay network, where multiple single-antenna node pairs want to exchange information by using a multiple antenna relay node. Due to the half-duplex constraint of the relay, the exchange of information takes place in two steps. In the first step, the nodes transmit their …
