Experimental study on wave propagation in railway cuttings at 950 MHz and 2150 MHz

摘要

High-speed rail line consists of a variety of complex terrain structures. To ensure the stability of radio signal transmission, 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 high speed railway cutting 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 measurement scenarios and configurations are presented in detail. 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 railway environment.
