摘　　要：研究了两类LTE系统在同一地理区域邻频部署时的共存干扰情况,使用System Vue搭建链路级仿真平台对1.8 GHz、1.9 GHz频段的LTE基站进行了干扰分析,给出了不同调制方式、不同保护带宽下引起的系统性能损失的仿真结果。结果表明,现有3GPP规定的射频指标不能确保两系统共存,并给出了降低干扰的建议。The co-existence interference is studied between the two LTE systems which deploy in an adjacent band in the same geographical region. Using System Vue, the link-level simulation platform is built. The interference is simulated in band 1.8 GHz and 1.9 GHz, and the simulation results of the system performance loss affected by different modulation method and different protection bandwidth are shown. According to the result, it can＇t make certain that the two systems coexist by the 3GPP RF specifications. Then it puts forward some suggestions to reduce the co-existence interference.
