蜂窝CDMA系统多区基站天线倾斜方案

A Beam-Tilting Scheme for Multi-Cell Base Stations of Code Division Multiple Access (CDMA) Cell System

在综合考虑整个蜂窝系统的情况下,结合环境阴影衰落深度等因素,分析了地面基站天线倾斜对CDMA系统整体容量的影响后,提出了一种CDMA系统多区基站的天线倾斜方案.该方案将基站天线倾斜技术应用于整个CDMA蜂窝系统.仿真结果表明,利用本方法可将CDMA系统容量得到明显的提高.

The capacity improvement mechanism with beam-tilting antennas for multi-cell base stations was studied under the consideration of the effect of log-normal shadowing, the height of antenna and the beam width. A beam-tilting scheme for multi-cell base stations of the CDMA cell system was proposed, in which beam-tilting technology for base stations is used in the whole CDMA cell system. The simulation results show that with the new scheme, the system capacity can be greatly improved.
