Measurement and Analysis of the Broadband Radio Propagation in a High-speed Railway Station

To ensure the stability of radio signal transmission in high-speed railway station, a detailed channel modeling for this special environment is essential and valuable. In this work, an evaluation of the performance of radio propagation in a real high-speed railway station scenario is conducted. The corresponding measurements in the actual environment are carried out with the assistance of hardware testbed at 950 MHz and 2150 MHz, respectively. The propagation in both Line of Sight (LOS) and None-Line of Sight (NLOS) conditions are considered and tested. The measurement scenarios and configurations are presented in detail. Furthermore, the key parameters, such as power delay profile, reverberation time are extracted from the broadband measurement results and compared at both frequencies to achieve a rational solution for broadband communication system applying in the development of next generation high-speed railway.
