“…Recently, the dual-hop RF-UWOC systems have received widespread attention since RF and UWOC technologies have been deployed together to achieve both advantages simultaneously [1]. The analytical expression for ABER of the dual-hop RF-UWOC system was derived for various binary modulation techniques in [6]. The secrecy performance of the dual-hop RF-UWOC systems was investigated in [7] and the closed-form expression for the intercept probability for the fixed-gain relaying (FGR) scheme was derived.…”

In this paper, we analyze the performance of a dual-hop radio frequencyunderwater wireless optical communication (RF-UWOC) transmission systems wherein the RF and UWOC links experience Nakagami-m fading and the mixture Exponential-Generalized Gamma fading, respectively. The location of S is uniformly distributed in the space of the hemisphere where the relay is located in the center of the hemisphere. The effect of bubbles level, temperature gradient, water types, and detection techniques are considered. We derive closed-form expressions for outage probability (OP) and average bit error rate (ABER) for both fixed and variable gain relaying schemes with different detection techniques. Furthermore, by utilizing the expansion of Meijer's G-function and Fox's H-function, the closed-form expressions for the asymptotic OP and ABER are derived when the average signal-to-noise ratio of both links tends to infinity. The analytical results are verified by Monte Carlo simulation results. Our results demonstrate that the diversity order of the dual-hop RF-UWOC systems depends on the RF fading parameter and detection technology of the UWOC link.

“…For this characterization, impact of thermal fluctuations, air bubble concentration, and saltiness or brininess of the underwater are taken into consideration. Using this EGG model for the UWOC link, BER performance for cascaded RF and UWOC system are studied in [15], in which the effects of fading and UOT on system's performance is investigated. This work presents outage analysis of the DF based relayed communication system where a dual-hop RF-FSO system is cascaded with an UWOC link.…”

This work presents outage analysis of a hybrid communication system, where radio frequency (RF) and free space optical (FSO) communication links transmit in parallel to the then cascaded underwater wireless optical communication (UWOC) link forming a RF/FSO-UWOC cooperative system. Optical wireless communication (OWC) is being used as a viable communication technology by researchers due to its advantages such as fast speed, cost effectiveness, and highly secure transmission. The proposed architecture connects the terrestrial and the underwater regions to form an end-to-end cooperative system. This hybrid RF/FSO back-haul link makes the system more reliable as the optical link is highly susceptible to weather conditions. The channel models considered are Nakagami-m distributed fading, Double Generalized Gamma (DGG) distributed atmospheric turbulence along with Rayleigh distributed misalignment losses and mixture of Exponential Generalized Gamma (EGG) distributed oceanic turbulence for RF, FSO, and UWOC links, respectively. Results show that outage performance is severely affected due to RF fading, DGG distributed irradiance, air bubble concentration, temperature gradient, and saltiness of water source
