摘　　要：TD-SCDMA采用智能天线、上行同步、联合检测、动态信道分配等技术使系统容量大大提高,系统投资成本也低于其他3G标准,因此研究容量仿真算法对TD-SCDMA系统的实用化具有现实意义。文章在介绍静态仿真概念、仿真场景、仿真方法的基础上,利用智能天线系统下的干扰计算方法,给出了一种理想功率控制下的TD-SCDMA系统容量仿真算法,并描述了仿真场景模型构架。TD-SCDMA system adopts advanced technologies, such as smart antenna, uplink synchronization, joint detection and dynamic channel allocation to increase the system capacity largely. Simultaneously, the cost of equipment investment for TD-SCDMA system is lower than that of other 3G systems with different standards. Therefore, the research of application of the capacity simulation algorithm in TD-SCDMA system is significant. In the paper, the concept of static simulation, configuration of simulation scenario and simulation methods are introduced first. Based on the interference algorithm of smart antenna system, a TD-SCDMA system capacity simulation algorithm under the condition of ideal power control is then discussed in detail. At last, the simulation model's realization framework is described.
