We develop the channel capacity of atmosphere turbulence links with carrier Bessel-Gaussian vortex localized wave. By this capacity model, we investigate the influences of atmosphere turbulence and carrier parameters on the channel capacity. The results show that as the increase of the refractive index structure constant, channel capacity of links decreases, with the increase of Quantum number M, the channel capacity increase. This work provides a theoretical basis for realizing high capacity atmosphere optical communication with carrier Bessel-Gaussian vortex localized wave.
Based on the power spectrum of the index fluctuation with the outer scale of seawater turbulence, we develop the channel capacity of oceanic turbulence links with carrier Bessel-Gaussian vortex localized wave. By this capacity model, we investigate the influences of seawater turbulence and carrier parameters on the channel capacity. The results show that higher rate of dissipation of kinetic energy per unit mass of fluid, larger inner scale, or lower dissipation rate of the meansquared temperature causes the higher channel capacity; the Bessel-Gaussian localized vortex wave with broader initial half-pulse width has stronger resistance to oceanic turbulent perturbation. This work provides a theoretical basis for realizing high capacity oceanic optical communication with carrier Bessel-Gaussian vortex localized wave.
