摘要
对市域铁路信号系统无线传输性能的关键影响因子进行分析,建立了基于GBSM(基于几何的随机模型)的无线信道仿真模型,针对关键影响因子提出相应措施对LTE(长期演进)系统网络性能进行优化,搭建仿真测试平台。仿真测试结果验证了在市域铁路环境下LTE技术能够满足信号系统的传输需求。
The key influencing factors that affect the wireless transmission performance of suburban railway signaling system are analyzed.A wireless channel simulation model based on GBSM(geometry-based stochastic model)is established.Corresponding measures are proposed to optimize the network performance of LTE(long-term evolution)system according to the key influencing factors,and a simulation test platform is built.The simulation test results verify that the LTE technology can meet the transmission needs of signaling system in suburban railway environment.
