提出了一种适用于毫米波光纤无线电(ROF)系统的新型光子频率下移技术，并进行了仿真验证。频移是基于副载波调制(SCM)的。带有副载波的光载波被注入到由射频正弦信号驱动的马赫-曾德尔调制器(MZM)或电吸收调制器(EAM)组成的移频器中。因此，通过SCM调制产生具有频移副载波的频移光载波。
A novel photonic frequency down-shifting technique for millimeter-wave-band radio-over-fiber (RoF) systems is proposed and verified by simulation. The frequency shifting is based on subcarrier modulation (SCM). An optical carrier with a subcarrier is injected into the frequency shifter consisting of a Mach-Zehnder modulator (MZM) or electroabsorption modulator (EAM) driven by a radio frequency sinusoidal signal. The frequency-shifted optical carrier with a frequency-shifted subcarrier is, thus, generated by SCM modulation.
