摘要
针对IEEE 802.11g标准的特性,引入邻频干扰函数作为定量研究系统邻频干扰的方法。通过模拟一种实际运行场景,对采用不同信道方案时接收信号质量进行分析与计算,得出的增大信道间隔将有效提升接收信号的质量和系统吞吐量,为CBTC系统的信道规划提供理论依据和参考。
The paper explains the IEEE 802. 11 g standard which is widely applied in Communication-Based Train Control system. Then for the features of IEEE 802. 11 g standard,a function of adjacent channel interference is introduced as a quantitative research method of adjacent channel interference of the system. The quality of the accepted signal between different channel schemes is analyzed and calculated by simulating a practical scenario,leading to the conclusion that greater channel spacing effectively improves the quality of received signals and system throughput.
