摘要
分布式基站是当前移动通信发展的潮流,是我国即将大力发展的TD-SCDMA通信网络的重要组成部分.它是基站的延伸,其射频拉远单元RRU可以放置在地铁,边远地区等信号盲区,对提高网络的覆盖能力起着重要的作用.鉴于此,对TD-SCDMA分布式基站的优势和系统设计作了描述,并对基于软件无线电技术的分布式基站射频拉远单元(RRU)的设计结构和数据的速率做了重点论述.
The distributed base station is the current trend of mobile communication development and it is an important part of the TD-SCDMA communications Network in China. It is the extension device of the base station and can be placed in the signal blind zone, such as Metro and remote area. It plays an important role to improve the network coverage. The advantages and system design of the distributed base station is discussed in this paper. The structure design and RRU rate in RRU based on the software radio technology are emphasized.
