摘要:
光载无线系统(ROF)目前已运用于移动通信、智能交通、室内通信覆盖等众多领域。本文提出并证明了基于光载波重利用以及上行链路频率下变换的60GHz的ROF全双工系统。该方案使得基站无需额外的激光源、光滤波器以及微波源,简化了系统基站的设计与成本。

Abstract:
Radio over fiber(ROF) system has been successfully applied in mobile communication, intelligent traffic control, indoor signal coverage, and other fields. A 60GHz millimeter-wave full-duplex radio-over-fiber (ROF) system is proposed and demonstrated based on a novel wavelength reuse and frequency down-conversion scheme for up-link. The complexity and cost of the base station is reduced due to no need of additional laser source, optical filter and millimeter-wave source.
