【摘要】 本文提出了一种新的无线系统结构:基于分布式天线的分布式虚拟小区网络.在新型无线系统结构里,虚拟小区可自主移动与改变面积,这有益于容量提高,给无线资源管理带来诸多方便;其次,在不考虑阴影效应和多径衰落的情况下,对虚拟小区的反向容量进行了理论计算分析,并与分布式天线系统进行了对比.理论分析证明,虚拟小区可以降低用户发射功率,从而减少多用户干扰,提高系统容量.更多还原

【Abstract】 In this paper, we proposed a novel wireless communications architecture: distributed virtual cellular network (DVCN) .In DVCN,virtual cell (VC) can remove and change area freely, which brings some benefits of capacity,wireless resource control and so on. Then without considering the shadowing and multipath fading, we evaluated the reverse link capacity of VC and compared it with distributed antenna (DA) system. The results show DVCN can reduce users’ transmit power, decrease multi-user interference and improve the reverse link capacity.更多还原
