DMIMO and Machine Learning Techniques for Enhanced BER and Data Rates in 5G Free‐Space Optical Communication

IET Optoelectronics, Volume 19, Issue 1, January/December 2025.
This study introduces a dual multiple‐input multiple‐output (MIMO) method to enhance bit error rate (BER) and Q‐factor in 5G free‐space optical (FSO) communication. By integrating spatial diversity, machine learning‐based modulation, and adaptive optical filters, the system achieves data rates up to 120 Gbps while improving signal quality by up to 80%.
