摘要:
传统的电磁环境监测手段无法实现城市轨道交通线路各无线通信系统运行环境的实时在线监测。通过分析传统监测方法的不足，结合无线电指纹识别算法，提出一种实时、在线的电磁环境监测系统及测试方案。以LTEM(基于长期演进技术的城市轨道交通车地综合通信系统)和TETRA(泛欧集群无线电)技术为例，阐述了无线电磁环境在线监测系统的组成、架构、工作流程及仿真核心干扰识别算法。该研究成果可为城市轨道交通无线通信系统的智能运维提供重要的技术支撑。
Abstracts:
Conventional electromagnetic environment monitoring methods cannot realize real-time online monitoring of the operating environment of various wireless communication systems in urban rail transit lines. By analyzing the shortcomings of conventional monitoring methods and adopting radio fingerprint identification algorithm, a real-time, online electromagnetic environment monitoring system and test scheme is proposed. Taking LTE-M system and TETRA technology as examples, the composition, architecture, workflow and simulation core interference identification algorithm of electromagnetic environment online monitoring system are expounded. The research results can provide important technical support for intelligent operation and maintenance of urban rail transit wireless communication system.
