基于TDD系统的高速磁悬浮软切换技术研究
Research on High Speed Magnetic Levitation Soft Handoff Technology Based on TDD System
摘要
Abstract
The maglev train is a kind of land transportation vehicle with a running speed of more than 600 km/h. In order to ensure the superior performance of the train during operation, this paper first analyzes the magnetic levitation vehicle-to-ground communication system. The high Doppler effect in high-speed environment leads to an increase in the system error rate. This paper designs a wireless network soft handover mechanism based on TDD system, including intra-partition handover and cross-partition handover, and designs the MAC layer frame structure. Finally, through simulation, it is concluded that the handoff success probability is 99.6% when the speed is 600 km/h, and the distance of the switching overlap area can be set to 264 m.关键词
