GSM-R无线干扰监测的研究

Research on Wireless Interference Monitoring of GSM-R System

在当前铁路运营中,GSM-R系统极易受到非法电台、GSM和CDMA基站等干扰,这些不易定位的干扰会危及铁路交通安全。提出在GSM-R基站附近加装无线干扰监测站的思路来完成对干扰信号类型、干扰原因及干扰源定位的判别,较好地实现GSM-R网络的净空,并具有实时的特点。

In present operation of high-speed railways, GSM-R systems often suffer interferences fromillegal radio stations and base stations of GSM and CDMA. These interferences are very difficult to belocated, which greatly endanger the railway transportation safety. The paper puts forward an idea of settingwireless interference monitoring station nearby GSM-R base station to distinguish types, causes and originof the interferences and achieve the clean of GSM-R network with characteristics of real-time processing.
