Analysis of Optical Wireless MIMO Communication in Underwater Medium.

Leveraging on the multiple-input multiple-output (MIMO) application for enabling high data rates and ensuring reliable communication between underwater platforms connected to underwater sensor network, this paper presents a comprehensive analysis of the performance of optical wireless MIMO communication systems depending on the various phenomena. The outage performance of an underwater optical wireless communication (UOWC) is obtained in analytical form using Meijer-G function. Aysmptotic expression of outage probability is also derived for high signal-to-noise ratio (SNR) regime. Results show that the destructive combined effect of the underwater turbulence, pointing error, attenuation and angle-of-arrival (AOA) on the outage performance can be reduced by applying the MIMO spatial diversity technique.
