On the Performance of mixed FSO-UOWC Communication System with the presence of Pointing Error

Proceedings of the 2nd International Conference on Smart Digital Environment, 2018
In this paper, the performance analysis of a dual-hop decode-and-forward (DF) mixed free space optical-underwater optical wireless communication FSO-UOWC communication system with the presence of pointing error impairments is addressed. The analyzed system consists of a source node S communicating with a destination node D through a relay R.
