摘　　要：通过系统仿真对2.1 GHz频段的LTE与WCDMA系统在邻频时干扰情况进行研究。采用3GPP标准中定义的LTE和WCDMA仿真参数,对共站和非共站2种LTE与WCDMA相对拓扑场景,以及4种典型的LTE带宽(5、10、15、20 MHz)分别进行仿真。仿真结果显示,非共站时干扰情况最严重。但在2种场景下,基站和终端设备只要满足3GPP标准定义的ACIR要求即可实现LTE FDD与WCDMA的邻频共存,不需要增加额外的保护措施。It analyzes the adjacent channel interferences between LTE and WCDMA in 2.1 GHz bands by the method of system simulation. The LTE and WCDMA simulation parameters are defined in the 3GPP standards. The results of the simulations,which assumed cell layouts of uncoordinated macro cellular deployment and coordinated macro cellular deployment and 4 LTE channel bandwidths（5,10,15,20 MHz）,shows LTE and WCDMA can achieve coexistence if base station and user equipment satisfy the requirements of 3GPP standards and no additional protective measures are needed.
