“…In [163]- [166], there are using DF protocol, and there uses AF protocol in [167]. According to the above discussion, AF protocol is easy to implement and low cost, but it cannot eliminate noise; DF protocol can completely eliminate the influence of noise, but the implementation complexity is high.…”

When the distance between the source and the target is long, the signal will be affected by atmospheric turbulence, weather conditions and obstacles, which cannot support the information transmission. One of the existing solutions is to use relay-assisted technology (RAT). It makes the communications between the source and the destination possible under better channel conditions by setting up relay between the source and the destination. There are few comprehensive articles about relay-assisted technology in OWC. To fill this gap, this paper introduces the RAT of indoor optical wireless communications (IOWC), outdoor optical wireless communications (OOWC) and underwater optical wireless communications (UOWC) in different application scenarios, which has a better effect than direct communication between source and destination. The relay protocols, channel models, modulation techniques under three relay modes are reviewed. Finally, challenges of RAT in OWC are put forward and potential solutions are also given.

“…The author verifies that the implementation of decode and forward (DF) relay has better performance than AF relay, as shown in Figure 18. To further improve the performance of PLC and IWOC cooperative system, researchers introduced relay technology into such IWOC indoor broadcast communication system [37,38,[68][69][70]. In [69], PLC link is connected with IWOC link through DF relay and becomes the backbone of IWOC link.…”

Optical wireless communications have attracted widespread attention in the traditional power industry because of the advantages of large spectrum resources, strong confidentiality, and freedom from traditional electromagnetic interference. This paper mainly summarizes the major classification and frontier development of power industry optical wireless technologies, including the indoor and outdoor channel characteristics of power industry optical wireless communication system, modulation scheme, the performance of hybrid power line, and indoor wireless optical communications system. Furthermore, this article compares domestic and foreign experiments, analyzes parameters for instance transmission rate, and reviews different application scenarios such as power wireless optical positioning and monitoring. In addition, in view of the shortcomings of traditional power technology, optical wireless power transfer technology is proposed and combined with unmanned aerial vehicles to achieve remote communication. At last, the main challenges and possible solutions faced by power industry wireless optical technologies are proposed.

Optical wireless communications (OWC) systems provide higher data rates in the unlicensed spectrum bands compared to traditional radio frequency (RF) wireless communications systems. OWC systems are categorized as free space optical (FSO) communications and visible light communications (VLC) for outdoor and indoor environments, respectively. In this paper, we propose a multihop serial RF, FSO, and VLC system and investigate the link performance for five different scenarios with amplify-and-forward and decode-and-forward relaying protocols under different channel conditions. Based on the SNR statistics, we show closed-form expressions for the outage probability for all scenarios and derive their diversity orders. In addition, we examine the accuracy and correctness of the derived expressions by means of Monte Carlo simulations. We further prove that the diversity order is a function of the severity of the RF links and the shaping parameters, the atmospheric turbulence, the pointing error in FSO links, the detection method, and number of links. Finally, the presented results complement and extend several results previously reported in the literature.
