Abstract

Due to multipath characteristics and the special structure, electromagnetic
wave propagation in subway tunnel greatly differs from other confined space. In this paper,
statistical characteristics such as root mean square (RMS) delay spread and Doppler spread
and Doppler shift of multipath channel in a typical subway tunnel are analyzed using the
ray-tracing method and the radio statistics theory. Simulation results show that Doppler
spread and shift increase with higher frequency and velocity. However, RMS delay spread
is smaller with higher frequency. Simulation results provide a reference for 4G and 5G
applications in subway.

Key words： subway tunnel; multipath channel; RMS delay spread; Doppler spread; raytracing
