Abstract :
Free-space optical data links (FSO) can provide high bandwidth and secure data transmission. Since channel impacts like fog or atmospheric turbulence are decreasing the network availability, a microwave (RF) backup link is desirable. In this paper, the maritime environment is considered. The impact of channel coding is studied for multi-aperture (MIMO) FSO links with different scintillation index. In addition, an adaptive coding scheme is proposed, maximizing the availability of the combined hybrid (RF/FSO) network regarding the full range of possible signal distortions.
