多径环境下TD-SCDMA系统容量分析

Analysis of TD-SCDMA Capacity in Multi-path Environment

针对上行链路，在多径环境下采用智能天线对具有理想功率控制的ＴＤ－ＳＣＤＭＡ系统容量变化进行了分析，考虑了来自本小区及相邻小区用户的干扰。在智能天线波束宽度不同的情况下，对ＴＤ－ＳＣＤＭＡ系统进行了仿真，结果表明，采用智能天线技术可以较大幅度提高系统容量。

This paper analyzes the enhancement of the system capacity in TD-SCDMA with ideal power control using smart antenna. The interference from both the self-cell users and the neighbor cells is taken into account. When different beam width of the smart antenna is adopted, the TD-SCDMA system is simulated, and the results of the simulation prove that the system capacity can be greatly improved since the smart antenna is adopted.
