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。
Abstracts:
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.
