GSM900M与CDMA天线之间干扰分析与研究

摘要

为解决电信、联通共建基站CDMA系统下行干扰GSM系统900 MHz上行的问题,讨论采用调整天线的水平距离与垂直距离及在基站侧增加抗干扰仪减小干扰的方法,并给出了测试结果.该方案的实施解决了CDMA系统下行干扰GSM系统900 MHz上行的问题.%In order to solve the problem of interference, which is caused by CDMA uplink to GSM system 900 MHz downlink , when China Telcom and China Unicom share their base station, the method adjusting of horizontal distance and vertical distance between the antenna or increasing anti-interference device for reducing interference is mainly discussed, and given the test results. The scheme solves the the problem of interference,which is caused by CDMA uplink to GSM system 900 MHz downlink.
