| 摘 要： | 文中在对TD-SCDMA,系统标准理解和智能天线原理分析的基础上,以8阵元均匀圆阵的智能天线为例从系统级对TD-SCDMA系统的上行容量进行了分析,结合仿真结果给出了智能天线对系统容量的影响.仿真结果表明,由于在TD-SCDAM系统中智能天线的使用,相比于全向天线背景噪声有明显的降低,并结合多用户检测技术,明显地提高了系统的上行容量.

| Abstract: | This paper analyzes the standard of TD-SCDMA and elements of SA, and with homogeneous circular smart antenna of eight arrays as an example, examines TD-SCDMA uplink capacity from system level. The simulation results indicate that some parameters of SA influence the uplink capacity. Simulation analysis also suggests that, with SA in TD-SCDMA systems, the noise background are obviously reduced as compared with omnidirectional antenna in the TD-SCDMA systems. And in comnination with MUD technique, the capacity of TD-SCDMA systems uplink is obviously raised. |
