摘要:
高速铁路列车的C3列控系统对GSM-R通信网络质量要求非常高，但是随着公网基站在铁路沿线布网越来越密，对铁路的干扰也越来越严重，并且不仅是明显的频点干扰。文章系统性说明通过测试试验发现公网基站设备存在杂散及三阶互调频率落在GSM-R频谱内，对高速铁路存在干扰；同时，发现加装杂散滤波器可以有效抑制干扰的影响，为后期的干扰排查指明了新方向。
Abstract:
CTCS-3 of High-speed trains has high requirements on the qualityof GSM-R communication network, but with the more and more dense network of current network base stations along the railway, the railway is interfered more and more seriously, and it is not just the obvious frequency points interference. It is found out through test that the equipment of network base stations have stray and the existence of spurious three order intermodulation frequency in the GSM-R spectrum, which have disturbance on high-speed railway. At the same time, it is found that adding stray filter can effectively suppress the interference, which points out a new direction for the later investigation of interference.
