智能天线对TD-SCDMA系统中小区干扰分布的影响

Influence of interference distribution with smart antenna in TD-SCDMAsystem

本文通过对TD-SCDMA系统上行链路进行系统级仿真,输出了不同场景下相邻小区和本小区干扰比均值,以此对比分析了智能天线和定向天线对小区间和小区内干扰的抑制情况,并给出有关工程措施建议,为TD-SCDMA系统组网提供指导性意见。

The mean ratio of interference from inter-cell to from intra-cell is given in different scene by system uplink simulation in this paper.The ability of interference suppression is compared with smart and directional antenna respectively.Some suggestions are also provided for TD-SCDMAnetwork planning.
