[en] Reconfigurable intelligent surface (RIS), nonorthogonal
multiple access (NOMA), and underwater optical
wireless communication (UOWC) are paradigms of technologies
that drive the development of communications nowadays. In this
paper, we investigate the performance of a NOMA-based RISassisted
hybrid radio frequency (RF)-UOWC system. Due to the
interruption of the direct link between the base station and the
ship floating on the surface of the water, communication will
be carried out via an RIS fixed to an intermediate building.
The ship works as a relay that redirects the received signal to
two underwater destinations simultaneously. In this paper, we
provide new analytical expressions for the outage probability
(OP), asymptotic analyses of the OP, and diversity order (D) to
gain insights into the system performance. The results showed
that the diversity order depends on the UOWC receiver detection
technique. In the end, we illustrated that the NOMA-based RISassisted
system significantly improves the outage performance of
hybrid RF-UWOC systems over a benchmark systems.
