Multicast Transmissions With Full-Duplex Amplify-and-Forward User Cooperation

open access: yesIEEE Access, 2020
In order to improve the multicast transmissions, a full-duplex (FD) user cooperation scheme is proposed. In this paper, the transmitter sends the common messages to two FD users, and each user forwards its received signals to its counterpart by amplify ...

Hybrid Full-Duplex and Alternate Multiple Relay Selection and Beamforming in AF Cooperative Networks

open access: yesIEEE Access, 2018
In this paper, multiple relay selection and beamforming techniques are applied to a dual-hop full-duplex (FD) amplify-and-forward relaying network. We show that our proposed techniques allow the selection to be adaptive to the residual self-interference (

Interference Channels With Full-Duplex Amplify-and-Forward Receiver Cooperations

open access: yesIEEE Access, 2020
This paper considers a two-transmitter and two-receiver interference channel (IC), where each transmitter sends a message to its desired receiver. In particular, the full-duplex (FD) amplify-and-forward (AF) protocol is adopted to build up the receiver ...

Adaptive AF/DF Selection With FD/HD Switching in Two-Way Relay Networks

open access: yesIEEE Access, 2017
The full-duplex (FD) and two-way relay are promising techniques for their high spectrum efficiency. However, the incompletely self-interference cancellation may reduce the performance gain of two-way relay networks, which operates in FD mode.

Enhanced Amplify-and-Forward Relaying in Non-Gaussian PLC Networks

open access: yesIEEE Access, 2017
Relaying over power line communication (PLC) channels has the potential to improve the reliability and robustness of many PLC-based applications. In particular, this paper proposes to enhance the energy efficiency (EE) of a dual-hop relaying PLC system ...

Differential transmission for amplify-and-forward Cooperative communications [PDF]

open access: yesIEEE Signal Processing Letters, 2005
In this letter, we propose a differential amplify-and-forward (AF) transmission scheme for a two-user cooperative communications system. By efficiently combining signals from both direct and relay links, the proposed scheme provides superior performance compared to those of direct transmissions with either differential detection or coherent detection ...
