Abstract

- In order to develop reliable communications links for high speed railway (HSR) systems, accurate models for the propagation channel are required. The radio channel properties in HSR scenarios are different from those in cellular scenarios not only due to the high velocity, but also due to the special construction elements and the type of surroundings along the train lines. This paper focuses on the influence of overhead line poles along the railway on the HSR communication channel. The overhead line poles affect the line-of-sight (LOS) communication path periodically, and also act as static and periodic scatterers along railway lines. We performed a measurement campaign at a carrier frequency of 2.4 GHz on the Guangzhou-Shenzhen dedicated high-speed train line in China. Based on the measurement result we propose a dynamic channel model considering periodic poles for HSR communication.
