| 摘 要： | 分布式天线系统通过在地理位置上分布式放置天线,增强了系统的覆盖性能,也提高了系统的分集增益和容量性能。通过自主搭建的信道测量平台,对室内分布式天线系统信道进行了测量,其中发端天线分布式放置,接收端天线集中放置,对数据分析表明,在不存在视距传输或者视距传输分量不明显的情况下,各发天线到收端的信道解相关特性良好,容量性能提高较大;反之则容量性能下降。系统容量与天线是否均匀放置也密切相关,天线均匀放置时,容量提高且分布更为均匀。 |

| Abstract: | In distributed antenna system, the antennas are distributed in the geographical positions, thus to enhance the coverage performance, diversity gain and capacity performance of the system. The indoor distributed antenna system channel measurement is carried out through independently-built platform. In this measurement, the transmit antennas are scattered and the receive antennas are placed together. The analysis on the measured data indicates that the capacity performance of the system is remarkably improved... |
