Abstract

In recent years, the high-speed railway has achieved rapid development in China. To ensure the operation security of high-speed trains, providing reliable communication services is the basic requirement. Since the complex radio propagation environment, the research on the high-speed wireless communication system performance evaluation methods has caused the concern of related researchers. In this paper, we introduce a new method, hardware-in-the-loop simulation (HILS) to measure and evaluate the system QoS (Quality of Services) performance in different mobile speed. We build the simulation system with a radio channel emulator and the GSM-R (Global System for Mobile Communication for Railway) network. In addition, we accomplish an accurate emulation of the propagation environment of Beijing–Shanghai high-speed railway testing segment with actual measured data. Based on this, we finally get the conclusion that the mobile speed has little impact on CSD (Circuit Switched Data) QoS performance, while affects GPRS (General Packet Radio Service) QoS performance obviously.
