  • Abstract: Signal-to-noise ratio (SNR) of an optical wireless communication (OWC) link that operates in anisotropic oceanic turbulence is evaluated.In order to find the SNR advantage of the anisotropy in the oceanic turbulent medium, SNR in anisotropic oceanic turbulence isnormalized by the SNR in isotropic oceanic turbulence. The dB values of this normalized SNR are examined versus the oceanicturbulence parameters of the ratio of temperature to salinity contributions to the refractive index spectrum, the rate of dissipation ofmean-squared temperature, the rate of dissipation of kinetic energy per unit mass of fluid at various oceanic anisotropic factors,avalanche multiplication factors, radii of receiver aperture, link lengths and detector responsivity values. It is found that as the oceanicturbulence becomes more anisotropic, at any link parameter, SNR of OWC link becomes advantageous over the isotropic counterpart.
