摘　　要：本文主要对TD-LTE多频段组网中的干扰问题进行分析。论文首先对TD-LTE可能的共址共存异系统工作频段进行了分析,指出了可能产生干扰的异系统和频段。并对不同干扰产生的原因分别进行了研究。在此基础上,论文提出了TD-LTE干扰隔离分析方法以及TD-LTE宏基站与其他系统共址时干扰隔离距离要求。通过对干扰隔离的计算,本文最终给出了TD-LTE室外宏站(F频段)、室外宏站(D频段)以及室分系统与其他系统共站时的干扰隔离结论。In this paper, the problems of interference in TD-LTE multi-band networldng are analyzed. Firstly, TD- LTE co-located coexistence interference with different system is analyzed and possible interference between different systems and bands, such as spurious interference, intermodulation interference and jamming, are researched. On this basis, this thesis proposes TD-LTE interference isolation analysis method and co-site interference isolation distance. Based on the interference isolation calculation, this paper finally gives the station interference isolation conclusions of TD-LTE outdoor macro station （F band）, outdoor macro station （D band） as well as the DAS system with other systems.
