Abstract

This reseach reports the design of fiber-wireless (FiWi) system for long optical backhaul. In order to prolong the transmission range, fully optical FiWi system with three channel pieces is utilized based on 4-QAM RoF-OFDM signal transmissiion from central-station to serve local home network for beyond 5G (B5G) applications with dynamic weather environments. The introduced architecture composes of fixed 100 Km single-mode-fiber (SMF) with DCF dispersion compensation technology followed via varied 160 Km optical-wireless-communication (OWC) transmission in presence of various fog-conditions, then fixed 10 Km SMF cable to cater the requirements of end-cuostomers. As a proposed concept, it is demonstratelly simulated a successful utilization of B5G integrated model without employing of equalization and filters. The system performance is analysed with varied OWC range with different pointing-error-angles under various haze environments such as clear-sky, light-fog, moderate-fog and heavy-fog. It is also evaluated via considering different VCSEL laser’s temperature. The error-vector-magnitude (EVM) and sample-error-rate (SER) are utilized as essential quality indecs. Ultimately, a fair comparison of our suggested model with other former researches has been made, the superiority has been obviously shown.

基于QAM-OFDM s波段传输的B5G框架恶劣雾条件下全光FiWi设计模型

本文报道了一种用于长距离光回程的光纤无线（FiWi）系统的设计。为了延长传输范围，采用3路全光FiWi系统，基于4-QAM RoF-OFDM信号从中心站传输，服务于动态天气环境下超5G （B5G）应用的本地家庭网络。所介绍的体系结构由采用DCF色散补偿技术的100公里固定单模光纤（SMF），通过各种雾条件下的160公里可变光无线通信（OWC）传输，以及满足终端用户需求的10公里固定单模光纤（SMF）电缆组成。作为一个提出的概念，在不使用均衡和滤波器的情况下，成功地利用了B5G集成模型。在晴空、轻雾、中雾、大雾等不同雾霾环境下，以不同指向误差角度的OWC范围对系统性能进行分析。并通过考虑不同VCSEL激光器的温度进行了评价。误差矢量幅度（EVM）和样本错误率（SER）作为基本质量指标。最后，将本文提出的模型与前人的研究成果进行了比较，显示出了明显的优越性。
