摘　　要：为了保障LTE室分覆盖需求,对LTE与CDMA室分信源1:1合路建设后的室内覆盖质量进行分析,通过对室内分布系统链路预算模型、设备功率、无线参数等多维度进行对比,给出了LTE与不同种类的CDMA室分信源1:1合路后的覆盖效果。当CDMA信源为宏站时,不能满足LTE覆盖需求;当CDMA信源为直放站时,能够满足LTE覆盖需求。In order to guarantee requirements of LTE indoor distribution coverage, the indoor coverage quality of LTE and CDMA indoor distribution system source 1：1 combination was analyzed. Multiple metrics of link budget model, device power and radio parameters were compared for indoor distribution system, and then coverage effect of 1：1 combination of LTE with different CDMA indoor distribution system sources were presented. When the system source of CDMA is macro station, the LTE coverage requirements can not be satisfi ed; When the system source of CDMA is the repeater, the coverage requirements can be met.
