Abstract

This paper proposes a dual-MIMO (DMIMO) free-space optical (FSO) communication system integrated with hybrid machine learning models (CNN and LSTM) to enhance bit error rate (BER), Q-factor, and data rates for 5G backhaul networks under atmospheric disturbances. Using OptiSystem software, we simulated the system's performance in fog, rain, haze, and snow environments. Results demonstrate data rates up to 120 Gbps and up to 80% BER improvement compared to conventional MIMO systems, especially under dense fog and turbulence. Although the proposed system shows excellent performance in both simulated conditions and also in experimental validation, real-world challenges such as sudden weather changes, pointing errors, and computational complexity were tested in both simulation and experimental environment. Future work will focus on implementing adaptive beam steering to enhance its validation in real-world situations to optimise the system for dynamic environments.

5G自由空间光通信中提高误码率和数据速率的DMIMO和机器学习技术
本文提出了一种结合混合机器学习模型(CNN和LSTM)的双mimo (DMIMO)自由空间光(FSO)通信系统,以提高大气干扰下5G回程网络的误码率(BER)、q因子和数据速率。利用OptiSystem软件,模拟了系统在雾、雨、雾霾和雪环境下的性能。结果表明,与传统的MIMO系统相比,数据速率高达120 Gbps,误码率提高了80%,特别是在浓雾和湍流条件下。尽管所提出的系统在模拟条件和实验验证中都表现出优异的性能,但在模拟和实验环境中测试了现实世界的挑战,如突然的天气变化、指向误差和计算复杂性。未来的工作将集中在实现自适应波束转向,以增强其在现实世界中的有效性,以优化动态环境下的系统。
