摘要
目前基于通信的列车控制系统(CBTC)很多采用IEEE 802.11标准的无线局域网(WLAN)技术来实现车-地信息交互;针对WLAN无线局域网通信系统存在的同频干扰问题进行分析研究;结合CBTC应用环境,提出抗干扰应对策略,以提高CBTC无线通信系统的健壮性和可用性。
Wireless Local Area Network technology following the IEEE 802.11 standard is widely applied to fulfill the information interaction between the train and wayside in communication-based train control system（CBTC）.Aimed at the prevalent co-channel interference problems of WLAN system,by analyzing and researching these problem causes,the anti-interference strategy is put forward to improve the robustness and availability of wireless communication of CBTC system.
