UAV Swarms as Amplify-and-Forward MIMO Relays [PDF]
2019 IEEE 20th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2019 Unmanned aerial vehicles provide new opportunities for performance improvements in future wireless communications systems. For example, they can act as relays that extend the range of a communication link and improve the capacity. Unlike conventional relays that are deployed at fixed locations, UAVs can change their positions to optimize the capacity ...

Adaptive Amplify-and-Forward Relaying for Cellular Downlink
IEICE Transactions on Communications, 2011 This paper presents an adaptive amplify-and-forward (AF)-type relaying method appropriate for the cellular downlink. The proposed method adaptively selects active relay stations (RSs) based on the path loss between each set of user equipment (UE) and the base station (BS) and that between each RS in order to avoid unnecessary enhancement of inter-cell ...
