Amplify-and-forward with partial relay selection

IEEE Communications Letters, 2008
This letter offers a statistical analysis of the basic two-hop Amplify-and-Forward link, where the relay node is selected based on instantaneous and partial knowledge of the channel. In contrast with previously reported work, where relay selection requires global knowledge (2 hops) of the relaying link, the problem considered is interesting in ...

Outage Probability and Average BER of UAV-Assisted Dual-Hop FSO Communication With Amplify-and-Forward Relaying

IEEE Transactions on Vehicular Technology, 2023
Unmanned aerial vehicles (UAVs) can be harnessed as relay nodes in free-space optical (FSO) communication systems to realize a flexible and cost-effective approach for delivering on-demand communication in next-generation wireless communications. However,

End-to-End Learning-Based Full-Duplex Amplify-and-Forward Relay Networks

IEEE Transactions on Communications, 2023
Full 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, 2021
In 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, 2022
In 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 ...

Scheduling for Amplify-and-Forward Cooperative Networks

IEEE Transactions on Vehicular Technology, 2007
We 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.

Estimation for amplify-and-forward transmissions with nonlinear amplifiers

2013 Constantinides International Workshop on Signal Processing (CIWSP 2013), 2013
This paper describes the development of a distributed estimation algorithm for amplify-and-forward sensor transmissions with realistic nonlinear amplifier models at the sensors. Specifically, an algorithm is developed that enables distributed estimation with amplifiers operating in the non-linear class AB region. In this system, a digital predistortion

Adaptive Amplify-and-Forward Cooperative Channel

2007 IEEE International Symposium on Information Theory, 2007
In 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 (
