摘要
为了解决近期地铁民用通信系统POI合路加入FDD-LTE、TD-LTE网络后产生的严重干扰问题,对主要以1.8 GHz频段区间为主的网络系统进行理论干扰分析和现场实地验证,提出相应的解决方案,从而减少运营商间互调干扰问题的发生。
In order to deal with the severe interference resulting from the POI combination of FDD-LTE and TD-LTE networks in civil metro communication systems, the theoretical interference analysis and on-the-spot validation of the network system at 1.8 GHz were conducted, and then the corresponding solution was put forward to reduce the intermodulation interference between operators.
