Over the past several decades, free-space optical (FSO) systems have gained a specific place in the wireless technology area. The application of these systems is advantageous for high bandwidth, a license free band and quick installation. The main drawback of FSO systems is their dependence on the state of the atmosphere causing deterioration of the FSO systems availability. One of the atmospheric effects which has an essential impact on the performance of the FSO systems is atmospheric turbulence. Atmospheric turbulence leads to fluctuation of the optical intensity in the plane of the receiving aperture. In our contribution the numerical simulation of the propagation of a Gaussian optical beam through a random inhomogeneous media is performed. Correct generation of the random phase screens which were used for imitation of the fluctuations of refractive index is also discussed. Using the simulation based on split-step Fourier method we analyze the effect of turbulent fluctuations of refractive index on the value of scintillation for different turbulent regimes. Thereafter, the results obtained from the simulation are compared with conventional numerical models.
