即使在毫米波段（mm波段）光纤无线电（ROF）系统中，波分复用（WDM）与副载波复用（SCM）相结合也是增加现有光频率交织光纤中的信道容量的实用且有吸引力的方式。在本文中，我们提出了一种选择的通道交错密集的WDM/SCM毫米波段ROF信号，使用光外差检测双模本地光。从理论上解释了该方案的原理，并通过实验验证了DWDM/SCM ROF信号在25 km长的标准单模光纤上传输后的信道选择。
Even in millimeter-wave-band (mm-wave-band) radio-on-fiber (ROF) systems, wavelength-division multiplexing (WDM) combined with subcarrier multiplexing (SCM) is a practical and attractive way to increase the channel capacity in existing optical-frequency-interleaved fibers. In this paper, we propose a channel selection scheme for interleaved dense WDM/SCM mm-wave-band ROF signals that use optical heterodyne detection with dual-mode local light. The principle underlying this scheme is explained theoretically, and channel selection of the DWDM/SCM ROF signal after transmission over a 25-km-long standard single-mode optical fiber has been experimentally demonstrated.
