IRS-Empowered Wireless Communications: State-of-the-Art, Key Techniques, and Open Issues
Ming Zeng, Ebrahim Bedeer, Xingwang Li +4
In this article, we overview intelligent reflecting surface (IRS)-empowered wireless communication systems. We first present the fundamentals of IRS-assisted wireless transmission.…
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…
