    BER Performance Analysis of Optical Wireless Communication System over Weak and Strong Underwater Turbulence Channels
    (Springer Science and Business Media Deutschland GmbH, 2023) Naik, R.P.; Shripathi Acharya, U.S.; Bhargava Kumar, L.B.; Krishnan, K.; Chung, W.-Y.
    In this paper, we have investigated the performance of an underwater wireless optical communication (UWOC) link employing single-input and single-output (SISO) and selection combining (SC) as receiver diversity for varying link-ranges. As the the link-range increases, then strength of turbulence between the underwater optical entities also increases. It is assumed that the distribution of light propagation in weak and strong turbulence UWOC channel as log-normal (LN) and gamma-gamma (GG) density functions, respectively. The analytical bit error rate (BER) equations of on–off keying modulated UWOC link have been derived for SISO and SC receiver diversity using hyperbolic tangent distribution for LN and power series for GG density functions. The analytical BER results are validated with the Monte Carlo simulations. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
