3D-printed actuator-based beam-steering approach for improved physical layer security in visible light communication
(Optica Publishing Group, 2022)
In this study, we present the design, manufacture, and implementation of a 3D-printed lens scanner-based beam steering for use in visible light communication (VLC) applications. The 5 cm x 5 cm scanner is designed for ...
Security and Reliability Performance of Noise-Loop Modulation: Theoretical Analysis and Experimentation
(IEEE-Inst Electrical Electronics Engineers Inc, 2022)
Security is a crucial feature of current (5G) and even more for future (6G) communication networks. While the innate nature of the wireless channel is an issue for guaranteeing security, its physical characteristics can ...
Secure Transmission for THz-Empowered RIS-Assisted Non-Terrestrial Networks
(IEEE-Inst Electrical Electronics Engineers Inc, 2023)
The non-terrestrial networks (NTNs) are recognized as a key component to provide cost-effective and high-capacity ubiquitous connectivity in the future wireless communications. In this paper, we investigate the secure ...
Cost-effective test-bed for secure visible-light communication
(Spie-Soc Photo-Optical Instrumentation Engineers, 2022)
This study presents a real-time hardware implementation of a novel physical layer security algorithm developed for visible-light communications (VLCs) based on precoded spatial modulation (SM). The demonstration was carried ...
Transmit precoding for physical layer security of MIMO-NOMA-based visible light communications
(VDE Verlag GmbH, 2021)
We consider the physical layer security (PLS) of non-orthogonal multiple access (NOMA) enabled multiple-input multiple-output (MIMO) visible light communication systems in the presence of a passive eavesdropper (Eve). In ...
Channel Estimation for DCO-OFDM Based VLC Systems in the Presence of Clipping Noise
(Institute of Electrical and Electronics Engineers Inc., 2020)
Visible Light Communication(VLC) has been considered as a potential access option for 6G wireless systems to solve performance limitation due to bandwidth shortage at radio frequency (RF) band. In VLC system, illumination ...
Breaking the Performance Gap of Fully and Semi-Supervised Learning in Electromagnetic Signature Recognition
(Institute of Electrical and Electronics Engineers Inc., 2023)
Intelligent electromagnetic signature recognition is one of the key technologies in Internet-of-Things (IoT) device connection, which can improve system security and speed up the authentication process. In practical ...
Slotted Aloha for Optical Wireless Communications in Internet of Underwater Things
(Institute of Electrical and Electronics Engineers Inc., 2023)
In this work, we design and analyse a Slotted ALOHA (SA) solution for Optical Wireless Communication (OWC)-based Internet of Underwater Things (IoUT). In the proposed system, user devices exchange data with an access point ...
