Reconfigurable Intelligent Surfaces based Cognitive Radio Networks
Abubakar U. Makarfi, Rupak Kharel, Khaled M. Rabie +3
Over the last decade, cognitive radios (CRs) have emerged as a technology for improving spectrum efficiency through dynamic spectrum access techniques. More recently, as research i…
Hardware Impaired Ambient Backscatter NOMA Systems: Reliability and Security
Xingwang Li, Mengle Zhao, Ming Zeng +4
Non-orthogonal multiple access (NOMA) and ambient backscatter communication have been envisioned as two promising technologies for the Internet-of-things due to their high spectral…
I/Q Imbalance Aware Nonlinear Wireless-Powered Relaying of B5G Networks: Security and Reliability Analysis
Xingwang Li, Mengyan Huang, Yuanwei Liu +3
Physical layer security is known as a promising paradigm to ensure security for the beyond 5G (B5G) networks in the presence of eavesdroppers. In this paper, we elaborate on a trac…
UAV-Aided Multi-Way NOMA Networks with Residual Hardware Impairments
Xingwang Li, Qunshu Wang, Yuanwei Liu +3
In this paper, we study an unmanned aerial vehicle (UAV)-aided non-orthogonal multiple access (NOMA) multi-way relaying networks (MWRNs). Multiple terrestrial users aim to exchange…
Secrecy Analysis of Ambient Backscatter NOMA Systems under I/Q Imbalance
Xingwang Li, Mengle Zhao, Yuanwei Liu +3
We investigate the reliability and security of the ambient backscatter (AmBC) non-orthogonal multiple access (NOMA) systems, where the source aims to communication with two NOMA us…
Hardware Impairments Aware Full-Duplex NOMA Networks Over Rician Fading Channels
Chao Deng, Meng Liu, Xingwang Li +1
A cooperative full duplex (FD) non-orthogonal multiple access (NOMA) scheme over Rician fading channels is considered. To be practical, imperfect successive interference cancellati…
Sum Rate Maximization for IRS-assisted Uplink NOMA
M. Zeng, X. Li, G. Li +2
An intelligent reflecting surface (IRS) consists of a large number of low-cost reflecting elements, which can steer the incident signal collaboratively by passive beamforming. This…
On the Performance of Non-Orthogonal Multiple Access over Composite Fading Channels
Khaled Rabie, Abubakar U. Makarfi, Rupak Kharel +4
This paper analyzes the performance of a cooperative relaying non-orthogonal multiple access (NOMA) network over Fisher-Snedecor F composite fading channels. Specifically, one base…
Reconfigurable Intelligent Surfaces-Enabled Vehicular Networks: A Physical Layer Security Perspective
Abubakar U. Makarfi, Khaled M. Rabie, Omprakash Kaiwartya +4
This paper studies the physical layer security (PLS) of a vehicular network employing reconfigurable intelligent surfaces (RISs). RIS technologies are emerging as an important para…
