Approaching Gaussian Relay Network Capacity in the High SNR Regime: End-to-End Lattice Codes [PDF]
We present a natural and low-complexity technique for achieving the capacity of the Gaussian relay network in the high SNR regime. Specifically, we propose the use of end-to-end structured lattice codes with the amplify-and-forward strategy, where the ...

Differential Amplify-and-Forward Relaying in Time-Varying Rayleigh Fading Channels [PDF]
This paper considers the performance of differential amplify-and-forward (D-AF) relaying over time-varying Rayleigh fading channels. Using the auto-regressive time-series model to characterize the time-varying nature of the wireless channels, new weights

UAV Swarms as Amplify-and-Forward MIMO Relays [PDF]
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 ...
