国内移动通信系统共建共享时的互调干扰分析

Analysis of intermodulation interference for all domestic mobile communication systems

在移动通信系统中,无源器件非线性带来的无源互调干扰会对系统性能产生较大影响,尤其在多系统合路或相邻站点建设的场景中,无源互调干扰的影响会非常严重。本文基于对通信系统中二阶、三阶、五阶和七阶无源互调的影响分析,结合不同运营商的移动通信系统使用频段等信息,全面分析了国内移动通信系统在独立建设、合路建设和邻站建设时可能面临的互调干扰,可为网络规划设计及建设提供重要参考。

In mobile communication systems,the intermodulation interference caused by the non-linearity of passive components may have a greater impact on the performance of systems,especially in a scene of multisystem combiners or sites deployed adjacent to each other.In this paper,we comprehensive analysis all the intermodulation interference faced by all mobile communication systems based on the third-order,the fifth-order and the seventh-order of passive intermodulation characteristics and with the frequency band of mobile communication systems for all mobile communication operators,which provide important reference for network design and construction.
