Performance Analysis of MIMO-Underwater Optical Wireless Communication

Underwater optical wireless communication (UOWC) is a promising technology for high-speed data transmission in underwater environments. UOWC uses light as the carrier signal, allowing for higher data rates compared to traditional acoustic methods. However, the underwater environment presents unique challenges, such as scattering, turbidity, temperature, salinity, and underwater particles. This research aims to analyze UOWC systems’ performance using Multiple-Input Multiple-Output (MIMO) technique which has the potential to improve the data transmission performance. The analysis compare the SISO (Single Input Single Output) and MIMO techniques in underwater environment for different types of water (low turbulence and turbid water). To this end, we assess key performance metrics, such as bit error rates (BER) and received optical power versus transmission range.
