| 摘 要： | 本文提出了基于分布式天线的CDMA码道动态空间分配接入系统.该系统将分布式天线分成若干组－天线子群.基站传输到各天线子群的码道信号是所有码道中的一个码道子集,子集中的码道元素随用户位移及天线子群服务容量的需要进行动态调整.该系统可以有效减少CDMA系统的码道间干扰,提高系统传输容量.

| Abstract: | CDMA CCSDA(Code Channel Space Dynamic Allocation Based on Distributed Antennas) is presented in this paper,which has multiple antennas that are divided into a number of groups.So,the area served by a base station are splited into numerorous sub cells.A Switch/Weightingsum Mixer module is used to allocate user specific signal to any antenna group in the base atation.CDMA CCSDA can reduce interference and increase capacity significantly because of its unique structure. |
