[摘要] 后台实时跟踪方法准确定位、分析W网完全覆盖高铁场景下,列车经过时载干比(Ec/Io)和宽带接收总功率(RTWP)急剧恶化的原因,得出突发网络负荷和干扰是影响高铁网络质量的关键因素。同时验证了双载波策略能快速有效解决高铁W网突发网络负荷及Ec/Io恶化等问题。认为双(多)载波策略是W网高铁建设规划设计解决负荷、容量和质量矛盾的唯一手段。

[Abstract] In this paper, we use background real-time tracking to determine the reason for sharp deterioration of Ec /Io and received total wideband power (RTWP) on a complete-coverage high-speed railway. Burst network load and interference are the key factors that affect the quality of high-speed railway. Due to rapidly improved network quality, double(multi) carrier will be the only way to resolve the contradiction of load, capacity and quality in W network high-speed railway construction planning and designing.
