| 摘 要： | 研究了基于光外部调制的方式产生60GHz光毫米波的全双工光纤无线(ROF)通信系统。实验利用29GHzRF源产生58GHz的光载毫米波,2.5Gbit/s OFDM信号作为下行数据信号调制到光载毫米波上并传输光纤20km,在基站与用户单元实现3.3m的无线传输。同时实现了下行信号中心载波重利用作为上行信号的光载波,2.5Gbit/s的OOK信号作为上行数据信号调制到光载波上经20km上行链路光纤传输至中心站。

| Abstract: | An integrated full-duplex radio-over-fiber system with 60GHz wireless OFDM mm-wave transmission by using external modulation was proposed and experimentally demonstrated.The experimental results show that the 58GHz optical millimeter-wave will be generated by 29GHz RF resource.2.5Gbit/s OFDM downstream signal are modulated on the 58GHz optical millimeter-wave.The modulated signal can be transmitted over 20km fiber,and 3.3m wireless distance can be realized simultaneously.2.5Gbit/s OOK-NRZ upstream data sign... |
