Özet (EN)

Demand for high-bandwidth underwater applications such as image and real-time video transmission, has been increasing parallel to the increase in maritime activities such as environment monitoring, navigation, ocean-pollution control, tactical surveillance, oil and gas field exploration, and coastal security. To satisfy this demand, underwater visible light communication (UVLC) has emerged as a high-capacity alternative to acoustic and RF signaling. One of the major impairments in UVLC systems is turbulence-induced fading as a result of temporal variations in temperature and salinity. Furthermore, unlike the horizontal links modeled with fixed turbulence strength, vertical links experience varying turbulence strength based on the depth-dependent temperature and salinity profiles. In this thesis, we consider a multiple-input multiple-output (MIMO) UVLC link over a vertical turbulence channel, which is modeled as the concatenation of multiple layers. Under the assumption of cascaded log-normal channel model, we derive the outage probability of vertical MIMO UVLC links and provide a quantitative analysis for the diversity gain in terms of the number of transmitter/receivers.
