摘要

提出了一种基于光纤连接的大规模分布式天线系统(M-DAS)的新架构，该架构提供了一种面向未来的解决方案，可以在扩展无线网络覆盖范围的同时提供高数据速率。光纤连接到各种无线信号的透明性允许同时分发多种服务。直接调制器或外部调制器的互调失真(imd)限制了基于rof的DAS的上行动态范围和下行功率效率，使用数字AGC将上行RF信号功率调整到光调制器可接受的动态范围。

Fiber-connected massively distributed antenna systems

A novel architecture on fiber-connected massively distributed antennas system (M-DAS) for providing a future-proof solution to deliver high data rates while extending the coverage of wireless networks is presented. The transparency of the fiber links to the various wireless signals allows for the simultaneous distribution of multiple services. Intermodulation distortions (IMDs) in directly modulator or external modulator limits the uplink dynamic range and downlink power efficiency in a ROF-based DAS, a digital AGC is used to adjust the uplink RF signal power to an acceptable dynamic range of optical modulator.
