摘要: 在基站采用智能天线的情况下,从理论上分析了GSM系统和CDMA系统增加容量的机制,给出了两种系统容量增加的一些定量计算结果。计算结果表明,两种系统的容量都能得到成倍的增加,其中CDMA系统容量增加更为明显。

关键词: 智能天线, 容量, 移动通信系统

Abstract: One of the effective means of increasing capacity ofmobile communication systems is the use of smart antenna at base stations. The principles of increasing capacity of GSM systems and CDMA systems using smart antenna at base stations are investigated. Estimations of the capacity increase for the two systems are also carried out. The results show that the capacity of the two systems can be increasedN-folds(N>1). CDMA systems havethe larger capacity increase than GSM systems.

Key words: smart antenna, capacity, mobile communication systems
