Wireless Channel Simulation and Measurement of Maglev Tunnel

According to the fading characteristics of wireless channel in Maglev scene, the wireless channel simulation in Maglev scene and wireless channel measurement based on software radio are mainly studied. The 3D tunnel maglev track model has been built, the cloudrt simulation platform has been used, the radio wave propagation in tunnel scene has been simulated based on ray tracing method, and the wireless channel characteristics have been extracted, It includes path loss model, root mean square delay spread and multipath characteristic statistics. The channel measurement system based on software radio is used. It is measured in a tunnel like environment, and the channel impulse response is obtained. The multipath statistical characteristics and maximum delay distribution are analyzed in detail. The multipath delay spread in the tunnel scenario is 45 ns. The simulation and measurement results are compared and analyzed.
