Abstract
This paper examines the performance of underwater wireless optical communication (UWOC) links using single-input and single-output (SISO) and selection combining (SC) receiver diversity techniques. To accurately model the effects of underwater turbulence on light propagation, the Malaga gamma (MG) distribution is employed for both weak and strong turbulence conditions. Analytical bit error rate (BER) expressions for on–off keying modulated UWOC links are derived for both SISO and SC receivers, utilizing the MG distribution’s power series representation. Monte Carlo simulations are conducted to validate the analytical BER results. The findings of this study provide valuable insights into the design and optimization of UWOC systems operating in various underwater environments.
