| 摘 要： | 提出了一种适合于分布式天线蜂窝系统的频率复用分割方法,在满足用户需求信干比的情况下极大的提高了系统的频谱效率。该方法与传统的复用分割方案相比,有效的提高的频谱效率,复杂度略有提高。仿真表明在用户最小需求为16kbps时,当系统中有50个用户时,系统容量大约提高了70%。

| Abstract: | This paper proposees a reuse partitioning (RP) scheme for the distributed antenna cellular system(DACS), which can improve the system capacity significantly by spatial division multi-access(SDMA).Simulation shows that the capacity of proposed RP scheme is higher than the traditional RP scheme.Furthermore,in the case of moderate load,the capacity of former scheme can be increased by 70% than the traditional one. |
