摘　　要：GSM-R网络在弱场地区无线覆盖方式较为特殊,且相应区段的无线传输环境复杂,易产生网内干扰。本文从弱场地区的覆盖方式出发,对弱场地区干扰的产生机理进行分析,在此基础上提出了弱场覆盖设计和优化的方法及原则,为GSM-R网络设计和优化提供参考。The manner of wireless coverage of GSM-R network is quite special in zone with weak field coverage and the environment of wireless transmission in such a zone is complicated that internal interference is prone to be caused.Starting from the coverage manner of network in weak field zone,the generation mechanism of the interference within weak field zone is analyzed.Furthermore,the approach and principle of designing and optimizing the coverage of weak field GSM-R is proposed to provide reference to actual project.
