Energy Efficiency of Full- and Half-Duplex Decode-and-Forward Relay Channels

IEEE Internet of Things Journal, 2022
This article studies the energy efficiency (EE) of a three-node decode-and-forward (DF) relay channel, where the relay operates in full-duplex (FD) or half-duplex (HD) mode.

Two Birds With One Stone: Exploiting Decode-and-Forward Relaying for Opportunistic Ambient Backscattering

IEEE Transactions on Communications, 2020
In this paper, we propose and analyze an opportunistic ambient backscatter (AmBack)-assisted decode-and-forward (DF) (i.e., ODF-AmBack) relaying scheme, where the relay can not only forward the signal from the source as in the traditional DF scheme but ...

A Stacked-Autoencoder Based End-to-End Learning Framework for Decode-and-Forward Relay Networks

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2020
In this work, we study an end-to-end deep learning (DL)based constellation design for decode-and-forward (DF) relay network. Firstly, we study both the one-way (OW) and two-way (TW) relaying by interpreting DF relay networks as stacked autoencoders ...
