A Two-Hop mmWave MIMO NR-Relay Nodes to Enhance the Average System Throughput and BER in Outdoor-to-Indoor Environments

open access: yesSensors, 2021
Millimeter-Wave (mmWave) bands are receiving enormous attention in 5G mobile communications, due to the capability to provide a multi-gigabit transmission rate. In this paper, a two-hop architecture for 5G communications with the capacity to support high

On relay selection for decode-and-forward relaying [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2009
In this letter, we consider a multi-relay network operating in decode-and-forward mode. We propose a novel relay selection method with a low implementation complexity. Unlike the competing schemes, it requires neither error detection methods at relay nodes nor feedback information at the source.

Power Efficient Decode-and-Forward Cooperative Relaying [PDF]

open access: yesIEEE Wireless Communications Letters, 2012
Cooperative communications have been proven to be effective in enhancing performance of wireless networks. In this letter, we introduce and propose adaptive relay-selection rules to offer a tradeoff between fairness and energy consumption at each node for a network with multiple, mutually cooperative nodes.

Rateless Coding over Wireless Relay Networks Using Amplify/Decode and Forward Relays [PDF]

open access: yesJournal of Electrical and Computer Engineering Innovations, 2013
In this paper two different rateless transmissionschemes are developed. In the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination.

Full-Duplex Relaying With Quantize-Map-and-Forward

open access: yesIEEE Access, 2018
The quantize-map-and-forward (QMF) has been recently proved to achieve the capacity of arbitrary networks within a bounded gap and optimal diversity-multiplex tradeoff performance.

Joint Channel-Network Coding for the Gaussian Two-Way Two-Relay Network

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
New aspects arise when generalizing two-way relay network with one relay to two-way relay network with multiple relays. To study the essential features of the two-way multiple-relay network, we focus on the case of two relays in our work. The problem of

A New Coding Paradigm for the Primitive Relay Channel

open access: yesAlgorithms, 2019
We consider the primitive relay channel, where the source sends a message to the relay and to the destination, and the relay helps the communication by transmitting an additional message to the destination via a separate channel.

Non-linear energy harvesting based power splitting relaying in full-duplex AF and DF relaying networks: system performance analysis [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2020
Wireless power transfer is considered as a novel solution for energy harvesting in wireless communication networks. In this paper, the system performance of the non-linear energy harvesting based power splitting relaying in the full-duplex relaying ...

Cooperative Spectrum Sensing Schemes with the Interference Constraint in Cognitive Radio Networks

open access: yesSensors, 2014
In this paper, we propose cooperative spectrum sensing schemes, called decode-and-forward cooperative spectrum sensing (DF-CSS) scheme and amplify-and-forward cooperative spectrum sensing (AF-CSS) scheme, in cognitive radio networks.
