Differential Amplify-and-Forward Relaying in Time-Varying Rayleigh Fading Channels [PDF]
, 2013 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
