中文摘要:
在 40 GHz 在收音机上纤维(RoF ) 的光调整的一个新奇计划系统被建议。它在 Mach-Zehnder 调节的人(MZM ) 的连续平行的结构产生光 QPSK/16QAM 信号。毫米波浪与光频率增加(OFM ) 被获得。而且,调整在上光波浪被转移到毫米波浪上。增加毫米波浪 RoF 系统的传播能力能被用来。
英文摘要:
A novel scheme of optical modulation in 40 GHz radio-over fiber (RoF) system is proposed. It generates optical QPSK/16QAM signals in a serial-parallel structure of Mach-Zehnder modulators (MZMs). The millimeter-wave is obtained with optical frequency multiplication (OFM). Furthermore, modulation on optical-wave is transferred onto millimeter-wave. It can be used to increase transmission capacity of millimeter-wave RoF systems.
