摘要

针对5G毫米波通信系统，提出了一种基于ARoF(模拟光纤无线电)传输的低成本移动前传设计。通过采用一种简单的集中式梳状源，产生与超密集波分复用无源光网络(UDWDM-PON)网格兼容的窄间隔相干平面光载波，宽带无线多输入多输出(MIMO)信号通过使用称为改进双二进制的高频谱效率数据调制，成功地在22公里的双向光纤链路上以无错误传输(误码率为10-9)传输。仿真光谱分析结果表明了该系统的可行性和有效性。此外，在相当合理的光功率灵敏度范围内获得了高质量的眼图，证实了系统的传输可靠性和良好的功率效率。

A new bidirectional analog radio over fiber transmission for 5G millimeter wave communication systems

In this paper, a low-cost mobile fronthaul design based on analog radio over fiber (ARoF) transmission is proposed for 5G millimeter wave communication systems. Through the adoption of a simple centralized comb source that produce narrowly spaced coherent flat optical carriers compatible with ultra-dense wavelength division multiplexing passive optical network (UDWDM-PON) grid, broadband wireless multiple-input multiple-output (MIMO) signals have been successfully delivered with error-free transmission (bit error rate of 10–9) over bidirectional fiber link of 22 km by means of using high spectral efficient data modulation called modified duobinary. The simulating spectral analysis results disclosed the feasibility and validity of the proposed system. Furthermore, high quality eye diagrams were obtained within quite reasonable optical power sensitivities confirmed the transmission reliability and also indicated the good power efficiency of the proposed system.
