| 摘 要： | 提出了一种基于双边带(DSB)部分载波抑制调制(OCS)方式的微波光纤传输(ROF)系统结构,实现了矢量信号的传输以及调制方式由8PSK到QPSK的转换,并使用光纤Bragg光栅(FBG)实现了光载波的重新使用,降低了系统的成本。分析了实验原理并搭建了实验链路,在中心站,采用光OCS方案产生并倍频加载了携带有1 Mbps的8PSK矢量信号的5 GHz微波信号,实验结果表明,在基站,使用FBG实现光载波重用的同时,微波信号频率由5 GHz上转换为10 GHz,传输的矢量信号调制方式由8PSK变为QPSK。通过光谱可以看出,实验链路成功实现了50 GHz nm波矢量信号的产生和传输。

| Abstract: | We experimentally demonstrate a simple vector signal transmission architecture to realize the vector signal conversion from 8PSK to QPSK and optical carrier reuse based on radio over fiber system with fiber grating.A 5 GHz microwave carrying 1 Mbps 8PSK-vector signal is optical frequency doubled by employing double sideband carrier suppressed(DSB-CS) modulation scheme and up-converted to 10 GHz,optical carrier reuse is realized via a FBG in base station,and the finally demodulated vector signal is QPSK.As s... |
