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,为了定量分析无源互调电平对移动通信的影响程度,通过合理假设,计算在不同链路插损条件下的无源互调电平值。运用干扰信号叠加理论和接收灵敏度方程,计算电磁波传播路径损耗,并利用室内信号传播模型分析覆盖范围受链路插损的影响程度。The passive inter-modulation （PIM） interference has already been the key factor affecting mobile communication performance and customer perception. In order to quantitatively analyze the impacts of PIM level on mobile communication, the level values of PIM in the condition of different path losses were calculated based on the feasible hypothesis. By means of the interference signal superposition theory and reception sensitivity equation, the propagation path loss of electromagnetic wave was calculated. In addition, the indoor signal propagation model was used to analyze the impacts of path losses on the coverage.
