摘要
GSM-R干扰主要来自系统外部和内部二方面,目前我国尚无针对GSM-R网络比较全面的无线干扰评价及测试方法。为此,按照工程建设初期阶段、工程验收阶段以及运行期间,对设备性能、网络干扰的监测和控制等进行总结,探讨GSM-R系统干扰的测试方法。
The interferences on the GSM-R mainly come from the outers and the internals of the system.At present,there is no comprehensive appraisal and test approach of wireless interference for GSM-R network.Therefore,in term of initial stage and acceptance stage of engineering construction as well as operation stage of the system,this paper summarizes the monitor and control of equipment performance,and network interference and probes the test method of GSM-R system interference.
