摘　　要：讨论了基于智能天线的TD-SCDMA系统上行链路干扰分布与中断概率分析模型,完成了仿真平台的设计与搭建。通过数值计算与静态仿真分析,给出了TD-SCDMA系统性能上界和中断概率,并说明满负载情况下,TD-SCDMA系统的上行干扰分布可以近似为对数正态分布。The uplink interference distribution and outage probability of the smart antenna based time division-synchronous code division multiple access （TD-SCDMA） system were analyzed, and a system level simulation platform was introduced. The performance upper bound and outage probability of TD-SCDMA system were obtained through numerical calculation and statistic simulation. The conclusion that the uplink interference distribution of full load TD-SCDMA system is similar to the lognormal distribution was also obtained.
