“…A 520 nm LD source operating modulated with 2.3 Gbps data using non-return to zero (NRZ) format is used in an UWOC system in (Oubei et al 2015). In (Shen et al 2016), an LD operating at 450 nm with 51.3 mW power is used with NRZ on-off keying (OOK) modulation to transmit a 1.5 Gbps over a distance of 20 m. The authors in (Ali and Rahi 2018) proposed an UWOC system based on using an LED source. Different modulation schemes are used like NRZ OOK and M-pulse position modulation (PPM).…”

This paper introduces a novel underwater (UW) optical communication system that utilizes optical code division multiple access transmission technique using the permutation vector code. Three scenarios of water are considered, pure sea (PS), clear ocean (CL), and coastal ocean (CO). The performance is evaluated analytically in terms of bit error rate (BER), received power, signal to noise ratio for different UW links and data rates. The results show that the shortest UW range is achieved in the case of CO, achieving the highest extinction ratio compared to CL and PS. Considering a BER below the forward error correction (FEC) limit of 3 × $${10}^{-3}$$ 10 - 3 , the maximum UW ranges reached are 21 m for PS, 12 m for CL, and 8 m for CO at 3 Gbps with 20 dBm transmitted power. The propagation range could be increased when the transmitted power is increased to 25 dBm, achieving the ranges of 31 m, 18 m, and 9 m, for PS, CL, and CO, respectively.

“…Numerous applications are deployed underwater where channel conditions emerge with a high-power LED-based VLC system. For real-time communication scenarios, the underwater sensor network nodes (UWSNs) are connected with visible light sources and further communicate with the base station (BS) [130]. The sensors positioning system and localization in the UVLC system have been drawn attention in the literature to support and improve system capacity and efficiency.…”

In recent years, underwater visible light communication (UVLC) has become a potential wireless candidate for signal transmission in highly critical, unknown, and acrimonious water mediums such as oceans. Unfortunately, the oceans are the least explored reservoirs in oceano-geographical history. However, natural disasters have aroused significant interest in observation and monitoring oceanic environments for the last couple of decades. Therefore, UVLC has drawn attention as a reliable digital carrier and claims a futuristic optical media in the wireless communication domain. Counterparts of traditional communications, the green, clean and safe UVLC supports high capacity of data-rate and bandwidth with minimal delay. Nevertheless, over long ranges, the deployment of UVLC is challenging rather than terrestrial basis communication. Additionally, VLC systems suffer from signal attenuation and strong turbulence channel conditions. Due to the fact that, this study provides an exhaustive and comprehensive survey of recent advancements in UVLC implementations to cope with the optical signal propagation issues. In this regard, a wide detail summary and future perspectives of underwater optical signaling towards 5G networks along with the current project schemes, channel impairments, various optical signal modulation techniques, underwater sensor network architectures with energy harvesting approaches, hybrid communication possibilities, and the Internet of underwater things (IoUTs) are concluded in this research.

This paper proposes the Optical Wireless Communication (OWC) for different Application, Advances and Challenges as high data rate multimedia services are evolving continuously and exponentially increasing the demand for wireless capacity 5G generation and upgrading Technologies. These are used to bypass the RF transmission band, which is inadequate to meet the demand for future high data rate 5G services. It offers services for both indoor and outdoor application as well as in the submerged area with contact distances ranging from nm to more than 10,000 km. This paper provides an overview and performance analysis of technical communication involving Visible light, Line of sight underwater, free space, optical communication, optical camera communication and light detection for all surveys of keys understanding technologies (OWCs) and presents them as aspects of criteria such as spectrum use, application, design, classification advances and challenges.
