摘要
对TD-LTE和已有系统基站共站址时天线干扰问题做了深入分析,给出了共站址时TD-LTE在D频段和F频段与GSM、DCS、TD-SCDMA、WCDMA、CDMA2000系统的天线隔离度和空间隔离距离,并对共站址天线安装时如何抑制天线干扰提出可以采取的一系列措施,从理论和工程实际上给出了TD-LTE和已有系统基站共站址建设的可行性。
It makes a deep analysis on the antenna interference problem of the co-site between TD-LTE and the system base station existing, and defines the antenna isolation degree and the spatial isolation distance between GSM, DCS, TD-SCDMA, WCDMA, CDMA2000 system and TD-LTE when in band D and band F when in co-site. And thus, it brings up a series of measures on how to suppress the interference of antenna when in installation co-site, and gives the feasibility of construction of TD-LTE and other system base station co-sites from theory and engineering practice.
