Data Rate Enhancement of FSO link using Quartet Double MIMO technique for 5G Networks

This contemporary study conducts extensive research on freespace optical (FSO) channels in various optical systems, aiming to evaluate and analyse popular frameworks. This study's main goal was to find a way to use the quadrature multiple input multiple output (Quartet Double-MIMO) technique to make free space optical communications (FSOC) less affected by atmospheric turbulence. The system employs double-boosted amplifiers to enhance the signal's strength and refines Bessel filters to reduce distortion, resulting in unparalleled transmission clarity and certainty. This structure significantly increases the ability to control beam dispersion and the range of the optical system. Additionally, the mentioned implied method reduces the bit error rate (BER), a measure of data transmission accuracy, and increasing the quality factor resulting in a more robust system.
