Abstract [en]
Wireless communication systems operating in different environments face significant challenges due to interference, mobility of communicating entities, and fluctuations in environmental conditions. Optical wireless communication (OWC) using ultra-violet (UV) light, particularly in the solar-blind region, offers a promising solution due to its low background noise, high directionality, strong anti-interference capabilities, and support for nonline-of-sight (NLoS) propagation. This thesis investigates the feasibility, benefits, and limitations of UV-based NLoS communication carrier in different environments. The purpose of the work is to understand the impact of interference from other frequencies, environmental variations, and mobility on UV communication carrier. A combination of literature review, theoretical system modeling, MATLAB-based simulations, and real-world experimental models has been used to achieve these objectives. The system model transmits UV light under NLoS conditions using atmospheric scattering to understand whether a communication link can be established. The results demonstrate that reliable UV signal propagation through scattering media is achievable; however, performance is influenced by factors such as receiver mobility, environmental conditions, and system design parameters. In general, the study concludes that NLoS UV communication represents a viable and secure method for wireless data transmission, provided that system configurations are optimized to account for environmental variability. This research contributes to the advancement of wireless optical technologies and offers valuable insight for future communication system designs in different environments and its settings.
