| 摘 要： | 在铁路专用无线通信网络GSM-R的建设过程中,干扰现象比较棘手。干扰是影响无线网络质量和传输可靠性的重要因素之一。在GSM-R系统中,干扰将引起误码增加、话音质量下降、数据传输差错率上升,干扰严重时会发生掉话、数据传输中断等现象,严重威胁列车的行车安全。介绍GSM-R干扰的分类、干扰产生的原因,并提出在铁路GSM-R网络建设的不同阶段,其干扰查找、定位及处理方法。

| Abstract: | The interference phenomenon is a tough problem in construction of GSM-R communication network. Interference is one of important factors affecting wireless network quality and transmission reliability. In the GSM-R system, interference will cause the error bits to increase, quality of voice to decline and data transmission error rate to rise. The call drop or interruption of data transmission may occur with interference arising. These all impose a serious threat to the safety of train operation. This paper i... |
