Abstract

ABSTRACT Microwave frequency down-conversion at 4.5 GHz using proposed photonic mixer is analyzed on various aspects in this manuscript. The proposed microwave photonic down-converter employs a Dual-Parallel Dual-Drive Mach–Zehnder Modulator (DP–DDMZM) that makes the system more compact than previously reported photonic mixers. Suppressed carrier modulation technique is used to increase the sideband power, which improves conversion efficiency by 20 dB as compared to dual-series modulator based mixer. To examine the performance of the proposed system for 5 G digital data transmission and reception, dispersion analysis over the length of fiber is performed. Furthermore, its performance for various digital modulation schemes is discussed.

下一代5G蜂窝系统中使用DP-DDMZM的微波光子混频器

本文从各个方面分析了利用所提出的光子混频器进行4.5 GHz微波频率降频的方法。所提出的微波光子下变频采用双并行双驱动马赫-曾德尔调制器(DP-DDMZM)，使系统比以前报道的光子混频器更紧凑。采用抑制载波调制技术增加边带功率，与基于双串调制器的混频器相比，转换效率提高了20 dB。为了检查所提出的系统在5g数字数据传输和接收方面的性能，进行了光纤长度上的色散分析。此外，还讨论了其在各种数字调制方案下的性能。

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
