Grassmannian Beamforming for MIMO Amplify-and-Forward Relaying [PDF]
IEEE Journal on Selected Areas in Communications, 2007 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.

Amplify-and-Forward in Wireless Relay Networks [PDF]
2011 IEEE Information Theory Workshop, 2011 A general class of wireless relay networks with a single source-destination pair is considered. Intermediate nodes in the network employ an amplify-and-forward scheme to relay their input signals.

Multicast Transmissions With Full-Duplex Amplify-and-Forward User Cooperation [PDF]
IEEE Access, 2020 In order to improve the multicast transmissions, a full-duplex (FD) user cooperation scheme is proposed. In this paper, the transmitter sends the common messages to two FD users, and each user forwards its received signals to its counterpart by amplify ...
