Abstract
Aiming at the shortcomings of cumbersome code writing and poor flexibility in traditional system design methods, this paper designs a wireless signal intelligent detection system based on software radio. The modular system design method is adopted to reduce the complexity of the design. Through the test on the high-speed comprehensive detection train, it is verified that the system can monitor the interaction process between the on-board equipment and the GSM-R network base station in real time, and realize the closed-loop monitoring of the vehicle-to-ground data transmission process. The receiving part and analysis part of the system can be connected through the network, and the flexibility of system deployment is increased by 7.3%.
