Abstract This work reports the implementation and experimental performance analysis of innovative 5G new radio (NR) photonically-amplified mobile backhauls and fronthauls. We claim to utilize fiber-optic links not only for data transmission and transport but also for amplifying ultrawideband radiofrequency (RF) signals from all mobile communication generations, including the current 5G and future 6G networks. The photonics-assisted RF amplification (PAA) digital performance investigation has been evaluated from baseband, for the first time in literature, to extremely high frequency (EHF), demonstrating the feasibility of using the proposed solution for enhancing the power efficiency and/or extending the backhaul link reach. Furthermore, the PAA-based 5G NR fronthaul deployment enabled to increase the system throughput in 12.3 times, attaining 13.5 Gbit/s, and providing root mean square error vector magnitude (EVMRMS) in accordance to the 3GPP requirements for bandwidths up to 400 MHz.

5G 新无线电光子放大 Xhaul

摘要 这项工作报告了创新的 5G 新无线电 (NR) 光放大移动回程和前程的实施和实验性能分析。我们声称将光纤链路不仅用于数据传输和传输，还用于放大来自所有移动通信代的超宽带射频 (RF) 信号，包括当前的 5G 和未来的 6G 网络。光子辅助射频放大 (PAA) 数字性能研究已在文献中首次从基带到极高频 (EHF) 进行评估，证明了使用所提出的解决方案来提高功率效率和/或扩展的可行性回程链路到达。此外，基于PAA的5G NR前传部署使系统吞吐量提高了12.3倍，达到13。
