| 摘 要： | 我国铁路GSM-R使用的E-GSM频段,极易受中国移动、中国联通等公网通信基站的干扰,影响GSM-R网络的系统服务质量和可用性,导致CTCS-3级列控系统降级、CIR语音通信掉话等。为此,在车载设备外增加外置干扰滤波设备进行干扰防护,有效地提高了车载无线通信设备的抗干扰能力。

| Abstract: | The GSM-R communication system for China Railway adopts E-GSM frequency band,which may be greatly affected by the blocking and inter-modulation interference caused by public communication network,such as China Mobile and China Unicom.These interferences frequently lead to the degradation in CTCS-3 systems and the call drops in CIR voice communication.In view of the above interference,We propose interference protection by add a adding external interference filter outside the on-board equipment.The experimental results validates that the proposed design significantly improve the anti-interference performance of vehicle wireless communication equipment. |
