Özet
Due to the important military and industrial application areas, the interest in underwater wireless optical communication (UWOC) systems, which can support real-time and high-speed data communication in the underwater environment, gradually increases. In order to design reliable UWOC systems, it is important to reveal realistic and accurate underwater wireless optical communication channel characteristics. UWOC channel, which has a very complex structure due to the unique optical characteristics of the underwater environment, can be fully modeled by the radiative transfer equation (RTE). However, it is difficult to find an exact analytical solution of RTE. In this study, Monte Carlo approach and its operation steps are given in detail for the high accuracy solution of RTE and obtaining UWOC channel characteristic. For the different water types commonly used in the literature, the impulse responses of UWOC channel have been obtained and instead of approximate models experimental measurements recognized in the literature have been considered for the high accuracy and precision of the channel characteristics. According to the obtained results, data communication distances of the UWOC system are compared for the considered water types.
