Abstract

This paper investigates the potential of Free Space Optical (FSO) communication technology for high-speed train (HST) systems by developing mathematical models for G2T-FSO (Ground to Train) communication links across single, curved, and double-curved tracks. The key contribution of this research is the introduction of novel G2T-FSO models, incorporating multiple transmitters (single, double, triple, and quad) and considering different weather conditions (clear, rain, and fog) using NRZ-OOK modulation. The models were evaluated based on key performance metrics, including received power, signal-to-noise ratio (SNR), bit error rate (BER), and eye diagrams. Simulation results reveal that single and dual transmitter links are significantly impacted by geometrical and atmospheric losses, while triple and quad transmitters provide error-free G2T-FSO links with a BER of 10-9. Under clear weather conditions, communication ranges of up to 680 meters for straight tracks and 618 meters for curved tracks were achieved. These findings highlight that G2T-FSO links deliver superior performance compared to traditional HST communication technologies, offering enhanced range, reliability, and data capacity for high-speed, secure train communication systems.

期刊介绍: Vehicular communications is a growing area of communications between vehicles and including roadside communication infrastructure. Advances in wireless communications are making possible sharing of information through real time communications between vehicles and infrastructure. This has led to applications to increase safety of vehicles and communication between passengers and the Internet. Standardization efforts on vehicular communication are also underway to make vehicular transportation safer, greener and easier. The aim of the journal is to publish high quality peer–reviewed papers in the area of vehicular communications. The scope encompasses all types of communications involving vehicles, including vehicle–to–vehicle and vehicle–to–infrastructure. The scope includes (but not limited to) the following topics related to vehicular communications: Vehicle to vehicle and vehicle to infrastructure communications Channel modelling, modulating and coding Congestion Control and scalability issues Protocol design, testing and verification Routing in vehicular networks Security issues and countermeasures Deployment and field testing Reducing energy consumption and enhancing safety of vehicles Wireless in–car networks Data collection and dissemination methods Mobility and handover issues Safety and driver assistance applications UAV Underwater communications Autonomous cooperative driving Social networks Internet of vehicles Standardization of protocols.
