Cooperative OFDM with Amplify-and-Forward Relaying with Timing Offset
Abstract—In this paper, we investigate cooperative OFDM communications using amplify-and-forward (AF) protocol at the relays, in the presence of imperfect timing synchronization....

Non-Coherent Detection for Amplify-and-Forward Relay Systems in a Rayleigh Fading Environment
— We consider about a multiple relay system operating under amplify-and-forward (AF) protocol and non-coherent modulation and demodulation. When the relays are under long-term po...

Beamforming with Limited Feedback in Amplify-and-Forward Cooperative Networks
— A relay selection approach has previously been shown to outperform repetition-based scheduling for both amplify-and-forward (AF) and decode-and-forward (DF) cooperative network...
