“…Two scenarios are proposed for the uplink and downlink transmissions between the Autonomous Underwater Vehicle (AUV) and the Unmanned Aerial Vehicle (UAV), subject to water-to-air and air-to-water interface impacts direct transmission scenario (DTS) and retro-reflection scenario (RRS) [26]. The outage probability and statistical characteristics of direct air-to-water wireless optical communication without relay are studied by considering the effects of turbulence and fog [27]. The author studied the propagation of Gaussian coherent beams from underwater laser emitters to outdoor receivers in the presence of gravity-generated water waves in the deep-sea plane through direct wireless communication of beams from underwater to airborne platforms [28].…”

In general, wireless relays are used for connecting wireless communication links, but relays can bring security and deployment issues. This paper investigates the performance of air-to-water communication systems without relay nodes. The probability density function (PDF) of the RF link is obtained by unifying α−μ, the extended generalized -K (EGK) and Fisher Snedecor (ℱ) distributions of atmospheric turbulence. We obtained the joint PDF of the RF/UWOC system for atmospheric turbulence and ocean turbulence with nonzero mean single-sided pointing error as well as air–water interface under foggy conditions. Based on statistical results, exact expressions for outage probability (OP), bit error rate (BER), and channel capacity (CC) were derived. Finally, we validated the analytical expression using Monte Carlo simulation. The simulation results show that the fading parameters of the channel have a significant impact on the performance of a without-relay-assisted RF/UWOC system.
