“…To further enhance the reliability and efficiency in communication systems, link-layer error-control methods, including redundancy and retransmission mechanisms, have been widely investigated in the context of FSO communications. A typical redundancy mechanism is the error correction code (ECC), which guarantees transmission reliability by adding some redundancies to the original message so that receivers can use them to recover the erroneous data [32]. In addition, ARQ is one of the well-known retransmission mechanisms, which facilitates the retransmission of erroneously received frames via feedback from the receiver to the transmitter [33], [34].…”

Free-space optical (FSO) communications have gained significant interest over the last few years, thanks to the capability to transport extremely high-speed data over long distances without exhausting radio frequency (RF) resources. FSO communication is widely considered in various network scenarios, such as inter-satellite/deep-space links, ground-station/vehicles, satellite/aerial links, or terrestrial links. It is expected to be a key enabling technology for the next generation of 6G wireless networks. Nevertheless, despite the great potential of FSO communications, its performance suffers from various limitations and challenges: atmospheric turbulence, clouds, weather conditions, and pointing misalignment. The error-control solutions, including physical layer (PHY) and link-layer methods, aim to mitigate the transmission errors caused by such adverse issues. While the existing surveys on error-control solutions in FSO systems primarily focussed on the PHY methods, we instead provide a review of link-layer solutions. In particular, we conduct an extensive literature survey of state-of-the-art retransmission protocols, both automatic repeat request (ARQ) and hybrid ARQ (HARQ), for various FSO communication scenarios, including point-to-point terrestrial, cooperative, multi-hop relaying, hybrid FSO/RF, satellite/aerial, and deep-space systems. Furthermore, we provide a survey of recent literature and insightful discussion on the cross-layer design frameworks related to link-layer retransmission protocols in FSO communication networks. Finally, the lessons learned, design guidelines, related open issues, and future research directions are exposed.

Free space optical (FSO) communication has established a reputation for itself capable of delivering high-speed data services over long distances without exhausting radio frequency (RF) resources.

“…The higher the data rate and the longer the link distance, the greater the impact of atmospheric turbulence. In order to resist atmospheric turbulence, using radio frequency (RF) link to cooperate with FSO [2][3][4], relay assisted transmission such as using unmanned aerial vehicles as relays [5][6][7], using deep learning to train the decision threshold of signal [8], Forward Error Correction (FEC) combined with interleaving and spatial diversity have been investigated [9][10][11][12][13]. Regarding the issue of communication interruption probability, theoretical research has been conducted in refs.…”

Free space optical communication (FSO) has become a popular research direction due to its high bandwidth, easy deployment, and inherent security. Its channel state is unstable because of atmospheric environment, especially in long‐distance ground transmission system. Interleaving combined with forward error correction coding (FEC) have been utilised to improve the stability of system. However, there is little detailed experimental results of deep interleaving combined with FEC under different atmospheric turbulence intensity over long‐distance FSO system. A deep interleaving with FEC method was designed and implemented on a 7 km long online experiment. The performance of different depth interleaving is analysed under weak and strong atmospheric turbulence state. The experiment results show that deep interleaving performs better under weak turbulence for the larger correlation factor of the channel and the outage probability of the system with deep interleaving can be greatly reduced.
