Abstract: CBTC（Communication-Based Train Control） usually employs the IEEE802.11g WLAN to implement its data communication.This paper simulates the overlapping effect and makes a quantitative analysis to the overlapping factors among the 11 wireless channels according to the characteristics of OFDM modulation and channel frequencies assigned by IEEE802.11g standard.Then the impact of overlapping effect among channels is assessed on the received signal quality in a scene for evaluation.
Key words: Communication-Based Train Control（CBTC）, IEEE802.11g, overlapping effect among channels, overlapping factor
摘要： 基于无线通信的列车控制系统一般采用IEEE802.11g标准无线局域网实现数据传输。根据IEEE802.11g标准的OFDM调制方式并结合其11个无线信道频率特性，研究不同信道间的频率重叠干扰情况，计算得到信道间干扰因子。然后在一应用场景中分析信道干扰对设备接收信号质量的影响，可为设计信道分配方案提供参考。
