| Abstract: | The Um interface is the air interface between onboard radio station (MT) and GSM-R network base station. This paper puts forward a monitoring system of Um interface based on software radio and introduces its system structure, data acquisition and processing scheme. Tests on the high speed comprehensive inspection train show that the system can monitor the process of interaction between on-board equipment and GSM-R network base stations in real-time, and realize closed-loop monitoring of data transmission process between the train and the wayside. |
