End-to-End Learning-Based Full-Duplex Amplify-and-Forward Relay Networks
IEEE Transactions on Communications, 2023Full duplex (FD) relaying can provide double spectral efficiency. Despite advanced self-interference cancellation techniques, residual self-interference (RSI) limits the performance significantly.

UAV-Assisted Free Space Optical Communication System With Amplify-and-Forward Relaying
IEEE Transactions on Vehicular Technology, 2021In this paper, the performance of an unmanned aerial vehicle (UAV)-based free-space optical relay system with amplify-and-forward relaying is analyzed. In particular, the statistical probability of end-to-end signal-to-noise ratio at the destination is ...

A Novel Average Autoencoder-Based Amplify-and-Forward Relay Networks With Hardware Impairments
IEEE Transactions on Cognitive Communications and Networking, 2022In this paper, we propose a novel Average autoencoder (AE)-based amplify-and-forward (AF) relay networks impacted by the I/Q imbalance (IQI) and additional hardware impairments (AHI), where the source and destination nodes are equipped with neural ...

Robust recursive filtering for uncertain stochastic systems with amplify-and-forward relays
International Journal of Systems Science, 2020This paper is concerned with the recursive filtering problem for a class of uncertain systems with amplify-and-forward (AF) relays. The parameter uncertainties are described by a set of norm-bounded matrices. An AF relay is located between the sensor and

Scheduling for Amplify-and-Forward Cooperative Networks
IEEE Transactions on Vehicular Technology, 2007We consider a basic cooperative network that is composed of three nodes which use Amplify-and-Forward as a cooperative strategy. This simple setup assumes that each time, one node is the source, one node is the relay, and one node is the destination.

Adaptive Amplify-and-Forward Cooperative Channel
2007 IEEE International Symposium on Information Theory, 2007In this work, we propose an amplify-and- forward (AF) protocol based on a new selection criterion, a function of the instantaneous capacities of all possible transmission schemes (with or without cooperation). The outage probability and the simulation results show that the new Adaptive AF protocol has better performance than the best known AF protocol (

Adaptive Amplify-and-Forward Relaying for Cellular Downlink
IEICE Transactions on Communications, 2011This paper presents an adaptive amplify-and-forward (AF)-type relaying method appropriate for the cellular downlink. The proposed method adaptively selects active relay stations (RSs) based on the path loss between each set of user equipment (UE) and the base station (BS) and that between each RS in order to avoid unnecessary enhancement of inter-cell ...

Lifetime Maximization for Amplify-and-Forward Cooperative Networks
2007 IEEE Wireless Communications and Networking Conference, 2007Joint relay-selection and power-allocation strategies are devised to prolong the lifetime of amplify-and-forward (AF) cooperative networks. Lifetime is defined as the time duration within which the desired signal-to-noise ratio (SNR) at the destination is met with a certain probability. Based on selective relaying, we propose three strategies that take

Cooperative Phase Sweep Amplify-and-Forward Transmission
2008 IEEE 68th Vehicular Technology Conference, 2008This work presents a new amplify-and-forward (AF) cooperative multiple input multiple output (MIMO) transmission scheme based on phase sweep transmit diversity. In a single hop cooperative link, the relay node imposes a phase sweep on the signal it receives from the source node.
