摘　　要：文章主要研究了TD-SCDMA系统和TD-LTE系统在同一地理区域邻频共存情况下由于系统间干扰造成的系统性能损失,给出并分析了在不同站间距、不同基站偏移、不同功率控制参数和不同带宽参数下,四个不同干扰场景的仿真结果。最后给出了一些减小干扰的措施与建议。This paper studied the system performance loss of TD-SCDMA and TD-LTE systems caused by coexistence interference between the two systems deployed in adjacent channels in the same geographic area.Four typical interference scenarios are simulated and discussed from different aspects： inter-site distances,system offsets between the two systems,power control parameters and system bandwidths.At last,a few suggestions and interference mitigation methods are introduced to better implement the two systems.
