Adaptive Sliding Mode Synchronous Control for Complex Networks With Amplify-and-Forward Relays

IEEE Transactions on Automation Science and Engineering
This paper aims to the remote synchronous control for complex networks with amplify-and-forward (AF) relays. Firstly, the AF relay dynamic with random noise is integrated into the control signal transmission.

Self-Identifying Amplify-and-Forward Relay for Localization Assistance

IEEE transactions on microwave theory and techniques
This article introduces a self-identifying relay that can assist in localization by adding unique code to the retransmitted data. The relay has an amplify-and-forward (AF) architecture that provides amplification and phase shift to the received signal ...

On the performance of roadside unit-assisted energy harvesting full-duplex amplify-and-forward vehicle-to-vehicle relay systems

AEU - International Journal of Electronics and Communications, 2020
This paper considers the performance of a full-duplex (FD) vehicle-to-vehicle (V2V) relay system where the relay uses amplify-and-forward (AF) protocol and harvests the energy from the radio frequency (RF) signals transmitted by source.

A Recursive Matrix Inequality Approach to Distributed Filtering Over Binary Sensor Networks: Handling Amplify-and-Forward Relays

IEEE Transactions on Network Science and Engineering
This article addresses the distributed filtering problem for a class of discrete time-varying systems over a binary sensor network (BSN) with amplify-and-forwarded (AF) relays, where the plant and binary measurements are subject to random noises that ...

Performance analysis of vehicle-to-vehicle communication with full-duplex amplify-and-forward relay over double-Rayleigh fading channels

Vehicular Communications, 2019
In this paper, we investigate a vehicle-to-vehicle (V2V) communication system where a full-duplex (FD) relay uses amplify-and-forward (AF) protocol. We consider two cases of the AF protocol at the FD relay, i.e.

Impact of I/Q Imbalance on Amplify-and-Forward Relaying: Optimal Detector Design and Error Performance

IEEE Transactions on Communications, 2019
Future wireless communication systems face several transceiver hardware imperfections that may significantly degrade their performance. In-phase (I) and quadrature-phase (Q) imbalance (IQI), which causes self-interference effects on the desired signal ...

Performance analysis of hybrid RF–FSO systems with amplify-and-forward selection relaying

Optics Communications, 2019
This paper presents performance analysis for two cooperative amplify-and-forward (AF) relaying systems in which hybrid combinations of radio frequency (RF) and free space optics (FSO) links have been considered, where the receiver employs the selection ...

Energy Efficiency of Amplify-and-Forward Full-Duplex Relay Channels

IEEE Wireless Communications Letters, 2019
In this letter, the energy efficiency (EE) for a three-node full-duplex (FD) relay channel with the amplify-and-forward (AF) scheme is studied. In particular, both the residual self-interference (RSI) and the circuit power consumption for imperfect self ...
