Optimal Amplify-and-Forward Precode and Relay Amplifying Matrices [PDF]
2013 IEEE 77th Vehicular Technology Conference (VTC Spring), 2013 A cooperative amplify-and-forward (AF) wireless relay scheme consisting of M sources, N relays, and L destinations all equipped with a single antenna is studied in this paper. The main objective is to design jointly and iteratively the closed-form of minimum mean square error (MMSE)-based source precode and relay amplifying matrices under a jamming ...

End-to-End Learning-Based Framework for Amplify-and-Forward Relay Networks
IEEE Access, 2021 We study end-to-end learning-based frameworks for amplify-and-forward (AF) relay networks, with and without the channel state information (CSI) knowledge. The designed framework resembles an autoencoder (AE) where all the components of the neural network

Amplify-and-Forward Relaying for Hierarchical Over-the-Air Computation [PDF]
IEEE Transactions on Wireless Communications, 2020 Over-the-air computation (AirComp) has emerged as a promising technique in future intelligent wireless networks, which enables swift functional computation among distributed wireless devices (WDs) by exploiting the superposition property of wireless ...

A New Store-Then-Amplify-and-Forward Protocol for UAV Mobile Relaying [PDF]
IEEE Wireless Communications Letters, 2020 In this letter, we consider the use of an unmanned aerial vehicle (UAV) as a mobile relay to assist the communication between two ground users without a direct link. We propose a novel store-then-amplify-and-forward (SAF) relaying protocol for the UAV to

Reliable Over-the-Air Computation by Amplify-and-Forward Based Relay
IEEE Access, 2021 In typical sensor networks, data collection and processing are separated. A sink collects data from all nodes sequentially, which is very time consuming.

Sequential slotted amplify-decode-and-forward [PDF]
2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013 In this paper, we propose a novel slotted hybrid cooperative protocol named the sequential slotted amplify-decode-and-forward (SADF) protocol and evaluate its performance in terms of diversity-multiplexing trade-off (DMT). The relays between the source and destination are divided into two different groups and each relay either amplifies or decodes the ...
