This research work examines the reliability of a wireless communication system that uses a hybrid radio frequency (RF) and underwater optical wireless communication (UOWC) in a dual-hop system. The proposed system consists of a single source (S) node that sends information to a destination (D) node through an amplify-and-forward (AF) relay (R) node using a multiple-input multiple-output (MIMO)-RF and UOWC links. The channel between the (S) node is subject to Nakagami-m fading using a transmit antenna selection (TAS) technique and maximal ratio combining (MRC) at (R) node, and exponential generalized gamma distribution (EGG) at (D) node to evaluate the overall statistical analysis of the proposed end-to-end(E2E) system. The proposed system has been extensively tested and validated under various conditions using a novel cumulative distribution function(CDF) and probability density function(pdf) whereas; the paper provides closed-form expressions for the outage probability (OP) and average bit error rate (BER) for each channel model.
