چکیده :

In this paper, we analyze the performance of a dual-hop mixed underwater optical wireless communication (UOWC)-multiple aperture free-space optical (FSO) relaying system by taking into account the effect of strong turbulence under pointing error (PE). To this end, we first derive a statistical channel model for the considered UOWC link alongside with the closed-form expression for its average bit error rate (BER). Then, we address the end-to-end average BER of the considered setup and we discuss the impact of PE in the UOWC link and the number of deployed receivers in the FSO link on different performance indicators. Simulation results are also included to validate the accuracy of our analysis.
