摘　　要：分布天线系统是后3G系统的主要研究方向之一,具有高系统容量与系统配置灵活的特性,本文提出了采用在WCDMA宏蜂窝网络中配置分布天线系统的方式来解决热点区域容量问题,分析与仿真结果表明在WCDMA宏蜂窝网络中配置分布天线系统是解决热点区域覆盖与容量问题的理想解决方案之一。Distributed antenna system (DAS) is the main research direction beyond 3G, previous researches have shown that high capacity potential and system configuration flexibility are two features of DAS. In this paper we present the scheme of deploying a CDMA distributed antenna system (DAS) with WCDMA macrocells in adjacent frequency bands. The main results of this study show DAS is a perfect candidate for providing coverage to high-traffic regions deployed with WCDMA macrocells.
