一种基于光载波抑制的ROF双工系统
An ROF duplex system based on optical carrier suppression
摘要
Abstract
In order to overcome the influence of dispersion in long-range fiber-optic transmission systems,we study a simplex Radio-Over-Fiber (ROF)system based on optical carrier suppression and propose an improved duplex ROF system transmis-sion scheme,in which the down-link signals are coupled to the optical carrier suppression band using 20 GHz RF signals at the central station and then transmitted to the base stations over a 50 km single-mode fiber,while the unmodulated sideband is re-used to transmit the uplink signals.The system spectrum diagram and BER curve generated in simulation show that when transmitted by coupling with uplink signals,the energy penalty of downlink signal is decreased and both the uplink and down-link become more dispersion resistant.关键词
