摘　　要：主要对TD-LTE系统F频段与GSM900系统间的干扰隔离问题进行分析。首先提出了TD-LTE宏基站与GSM900系统共址时干扰隔离距离理论要求,并在此基础上,对F频段与GSM900的隔离距离进行多次验证测试研究,对比分析各种隔离距离场景下的LTE网络吞吐能力。通过LTE网络建设中的实施应用,最终给出了TD-LTE室外宏站(F频段)与GSM900系统共站时的干扰隔离结论。Interference isolation of TD-LTE System F Band and GSM900 is analyzed in this paper. The theoretical requirements on interference distance in the case of co-location of TD-LTE macro base station （BS） and GSM900 are presented. Based on them, repeated tests are conducted for the isolation distance of F band and GSM900, and the throughput of LTE network in different isolation distances is compared and analyzed. Implemented and applied in LTE network construction, the final conclusion on interference isolation in the case of co-location of TD- LTE outdoor macro BS （F band） and GSM900 is presented.
