无源互调对室内分布系统覆盖范围影响分析

摘要

无源互调干扰已经成为影响移动通信性能指标及客户感知的重要因素，本文从无源互调产生机理入手，通过合理假设，运用干扰叠加原理，计算无源互调引起室内分布接收机灵敏度下降，利用路径损耗传播模型计算基站覆盖范围。%With the introduction of 3G and LTE, the interference produced by Passive InterModulaion (PIM) has become a major issue both from customer perception and for mobile network performance. This paper presents the mechanisms of PIM production. By the reasonable hypothesis and with interferences addition, the sensitivity is calculated with and without PIM interference present. The effects of PIM on indoor distribution system coverage are presented with the aid of mobile communication propagation model.
