Cooperative NOMA Meets Emerging Technologies: A Survey for Next-Generation Wireless Networks
Mahmoud M. Salim, Suhail I. Al-Dharrab, Daniel Benevides Da Costa +1
The emerging demands of sixth-generation wireless networks, such as ultra-connectivity, native intelligence, and cross-domain convergence, are bringing renewed focus to cooperative…
Beamfocusing and Power Allocation for AN-Based PLS in Multiuser XL-MIMO with Multiple Eavesdroppers
Xiangjun Ma, Ali Arshad Nasir, Daniel Benevides da Costa
This paper investigates the downlink (DL) physical layer security (PLS) in a near-field (NF) extra-large multiple-input multiple-output MIMO (XL-MIMO) system. To enhance the secrec…
Counteracting Eavesdropper Attacks Through Reconfigurable Intelligent Surfaces: A New Threat Model and Secrecy Rate Optimization
George C. Alexandropoulos, Konstantinos D. Katsanos, Miaowen Wen +1
The potential of Reconfigurable Intelligent Surfaces (RISs) for energy-efficient and performance-boosted wireless communications is recently gaining remarkable research attention,…
Performance Analysis of UAV-based Mixed RF-UWOC Transmission Systems
Sai Li, Liang Yang, Daniel Benevides da Costa
In this paper, we investigate the performance of a mixed radio-frequency-underwater wireless optical communication (RF-UWOC) system where an unmanned aerial vehicle (UAV), as a low…
Outage Probability and Capacity Scaling Law of Multiple RIS-Aided Cooperative Networks
Liang Yang, Yin Yang, Daniel Benevides da Costa +1
In this letter, we consider a dual-hop cooperative network assisted by multiple reconfigurable intelligent surfaces (RISs). Assuming that the RIS with the highest instantaneous end…
Backscatter Cooperation in NOMA Communications Systems
Weiyu Chen, Haiyang Ding, Shilian Wang +3
In this paper, a backscatter cooperation (BC) scheme is proposed for non-orthogonal multiple access (NOMA) downlink transmission. The key idea is to enable one user to split and th…
