Performance bounds of dual-hop hybrid RF-UWOC system with inverse Mellin transform

This is the authors' abstract. We don't add key points for this paper.

The performance bound of a hybrid radio frequency-underwater wireless optical communication (RF-UWOC) system with inverse Mellin transform is investigated. The RF link obeys the Nakagami-m distribution while the UWOC link undergoes the mixture Exponential-Generalized Gamma(EGG) distribution under heterodyne detection and intensity modulation direct detection. In the first place, the inverse Mellin transform technique is applied to derive closed expressions for the upper bound of the probability density function (PDF). By capitalizing on these statistics, the boundaries of the outage probability, the average bit error rate, and the average channel capacity are acquired. The expressions are verifified by the Monte Carlo simulation. The results indicate that the performance of the system is superior when the relay gain is the second case.
