Abstract

We discussed the influence of weak turbulent seawater on the capacity of underwater optical communication channel. A channel capacity model of shifted and deflected Bessel Gaussian beam links is derived. The results show that the channel capacity decreases as the rate of dissipation of kinetic energy per unit mass of fluid and the inner scale decrease, and it increases as the increase of the dissipation rate of the mean-squared temperature as well as the outer scale. And the channel capacity increases with the increase of the number of channels and the decrease of the angular half-aperture of the cone and shift.
