Grassmannian beamforming for MIMO amplify-and-forward relaying [PDF]
IEEE Journal on Selected Areas in Communications, 2008 In this paper, we derive the optimal transmitter/ receiver beamforming vectors and relay weighting matrix for the multiple-input multiple-output amplify-and-forward relay channel. The analysis is accomplished in two steps. In the first step, the direct link between the transmitter (Tx) and receiver (Rx) is ignored and we show that the transmitter and ...

A New Store-Then-Amplify-and-Forward Protocol for UAV Mobile Relaying [PDF]
IEEE Wireless Communications Letters, 2020 In this letter, we consider the use of an unmanned aerial vehicle (UAV) as a mobile relay to assist the communication between two ground users without a direct link. We propose a novel store-then-amplify-and-forward (SAF) relaying protocol for the UAV to
