Modeling of the Chaotic Signals Propagation Through a Wireless Underwater Optical Communication Channel

Analysis and Simulation of BER Performance of Chaotic Underwater Wireless Optical Communication Systems

“…Analysis of the simulation results and experimental studies carried out by various authors [47,52] showed that the greatest connection range can be achieved using on-off-keying (OOK) modulation [53] in conjunction with correction codes that improve the noise immunity of the communication system. Other modulation methods, including orthogonal frequency division multiplexing (OFDM) [53], quadrature amplitude modulation (QAM) [53], pulse-amplitude modulation (PAM) [53], pulse-position modulation (PPM) [53], discrete multitone modulation (DMT) [53], due to multiposition, allow for high data transfer rates, but the connection range does not exceed several tens of meters at best, even when using a collimated light source in the form of laser diodes [47,52]. In [47], the authors show that the most promising methods for transmitting information through an underwater optical communication channel using chaotic oscillations are methods based on matched filtering (correlation reception) on the receiving side.…”

Among these methods, chaotic on-off keying (COOK) [54,55] and the method of chaotic modes switching [55][56][57][58] should be noted.…”

“…In addition to ease of implementation, the Monte Carlo method has significant advantages, such as high solution accuracy and flexibility in setting the model input parameters, allowing photon tracing and dispersion and scattering in the communication channel [46]. These advantages make it possible to apply the Monte Carlo method to simulate the propagation of broadband signals through an underwater optical communication channel [47]. The reliability, accuracy and efficiency of the Monte Carlo method have been confirmed by a large number of theoretical and experimental studies [48].…”

“…Modeling of an underwater wireless optical communication channel is implemented in MAT-LAB based on the numerical solution model of the radiative transfer equation using a modified Monte Carlo method [47].…”

“…Modeling is carried out for the following types of water: clear ocean water, coastal water, harbor water. The values of the absorption and scattering coefficients used in the calculations for each type of water are given in [47].…”
