摘要
介绍了LTE系统在北京地铁范围内进行系统覆盖时,多系统间干扰问题的分析及计算。本文通过北京地铁这样的特殊场景,结合LTE系统的特点,辅以理论分析及现场测试,分析了在多系统(地铁信号系统、其他运营商等)环境下,在大客流、高速度及系统复杂的地下轨道空间内建设并使用LTE系统的方法。
When the LTE systems covered in the Beijing subway range, analysis and calculation of interference problems between multiple systems were introduced： Through this particular scene in Beijing subway, combined with the characteristics of an LTE system, supplemented by theoretical analysis and field testing, multi-system environment （subway signal system, other operators, etc.）, the construction in the large passenger flow, high speed and system of complex underground orbit space and the use of LTE system were analyzed.
