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

Full Duplex AF and DF Relaying Under Channel Estimation Errors for V2V Communications
In this paper, we investigate the outage performance of full-duplex (FD) and half-duplex (HD) vehicle to vehicle (V2V) networks. We consider two vehicular communication scenarios with the assistance of roadside unit (RSU), i.e., RSU-to-vehicle-to-vehicle
