Simulation and Research on Vehicle-ground Communication Channel of Maglev Train

In view of the influence of physical environment on radio wave propagation during the operation of high-speed maglev train, this paper establishes maglev rail transit viaduct and tunnel scene models, and uses Cloud RT simulation platform to simulate wireless communication based on ray tracing method in different frequency bands of 3.5GHz and 38GHz. According to the simulation results, channel characteristic parameters such as path loss and delay spread are deduced, which can provide reference for the deployment of MMW railway communication system.
