Research on Power Distribution Method of OFDM System with Hybrid Energy Supply under Fast Fading Channel
(IEEE, 2021)
An adaptive power allocation by minimizing grid power consumption for the Orthogonal Frequency Division Multiplexing (OFDM) system with the hybrid energy supply under a fast fading channel is proposed in this paper. To ...
Channel Estimation and Physical Layer Security in Optical MIMO-OFDM based LED Index Modulation
(IEEE, 2023)
In this paper, we propose a new and low-complexity channel estimation algorithm for the generalized LED index modulation (GLIM), recently proposed for visible-light communication systems based on multi-input multi-output ...
Physical Layer Security Under the Effect of Dimming in Visible Light Communications
(IEEE, 2023)
Visible Light Communication (VLC) is a promising option for 6G wireless systems to increase performance and provide a high-speed data rate compared to radio frequency (RF). Dimming control is one of the most important ...
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 ...
Cost-effective test-bed for secure visible-light communication
