“…Analysis of the simulation results and experimental studies carried out by various authors [47,52] showed that the greatest connection range can be achieved using on-off-keying (OOK) modulation [53] in conjunction with correction codes that improve the noise immunity of the communication system. Other modulation methods, including orthogonal frequency division multiplexing (OFDM) [53], quadrature amplitude modulation (QAM) [53], pulse-amplitude modulation (PAM) [53], pulse-position modulation (PPM) [53], discrete multitone modulation (DMT) [53], due to multiposition, allow for high data transfer rates, but the connection range does not exceed several tens of meters at best, even when using a collimated light source in the form of laser diodes [47,52]. In [47], the authors show that the most promising methods for transmitting information through an underwater optical communication channel using chaotic oscillations are methods based on matched filtering (correlation reception) on the receiving side.…”

“…The underwater optical communication channel is a combination of a module that determines the output signal of the communication channel based on the known impulse response of the channel in the absence of external noise sources, and a module that adds the noise signal to the output signal of the communication channel. Both the noise signal added to the signal for testing the noise immunity of the system and the background noise consisting of black body radiation and underwater ambient light are taken into account [32,63].…”

“…In [32], a platform with a graphical user interface for simulation and the results of modeling an underwater optical communication system are discussed. The proposed system is based on a light-emitting diode (LED) with a wavelength of 532 nm and a power of 1000 mW, an avalanche photodiode as a receiver, and the OOK modulation method.…”

“…The rapid developments of wireless communication technologies such as telecommunications and underwater communications − lead to increasing concerns on the issue of electromagnetic pollution, which is becoming a serious global problem. − The exposure of electronic devices to strong electromagnetic fields may cause the failure and degradation of electronic devices, and the created electromagnetic radiation will even threaten human health. To avoid the hazard of the electromagnetic interference (EMI), intensive research attention in material science has been paid to developing high-performance EMI shielding materials.…”

Strong electromagnetic wave reflection loss concomitant with second emission pollution limits the wide applications of electromagnetic interference (EMI) shielding textiles. Decoration of textiles by using various dielectric materials has been found efficient for the development of highly efficient EMI shielding textiles, but it is still a challenge to obtain EMI shielding composites with thin thickness. A route of interfacial engineering may offer a twist to overcome these obstacles. Here, we fabricated a Ni nanoparticle/SiC nanowhisker/carbon cloth nanoheterostructure, where SiC nanowhiskers were deposited by a simple manufacturing method, namely, laser chemical vapor deposition (LCVD), directly grown on carbon cloth. Through directly constructing a Ni/SiC interface, we find that the formation of Schottky contact can influence the interfacial polarization associated with the generation of dipole electric fields, leading to an enhancement of dielectric loss. A striking feature of this interfacial engineering strategy is able to enhance the absorption of the incident electromagnetic wave while suppressing the reflection. As a result, our Ni/SiC/carbon cloth exhibits an excellent EMI shielding effectiveness of 68.6 dB with a thickness of only 0.39 mm, as well as high flexibility and long-term duration stability benefited from the outstanding mechanical properties of SiC nanowiskers, showing potential for EMI shielding applications.

“…On the other side, the features of the water channel do not affect RF waves but the electrical conductivity of the water does. Additionally, RF is costly and only has very limited communication ranges [3]. In the literature, efforts have been devoted to characterizing the UOWC model systems and analyzing the performance.…”

The combination of radio-frequency (RF) communication and underwater optical wireless communication (UOWC) plays a vital role in the underwater Internet of things (UIoT). This correspondence proposes a dual-hop hybrid satellite underwater system that exploits non-orthogonal multiple access (NOMA) as a spectrum-efficient access technique. The RF link from the satellite to the relay on an oil platform is presumptively subject to a Shadowed-Rician (SR) fading, while the UOWC channels from the relay to the underwater destinations are suggested to follow Exponential-Generalized Gamma (EGG) distributions. The reliability of the system is characterized in terms of both underwater destinations and system outage probabilities (OPs). We derive new closed-form expressions for the OPs under imperfect successive interference cancellation (SIC) conditions. Furthermore, the asymptotic OP and the diversity order (DO) are obtained to learn more about the system's performance. The results are verified through an extensive representative Monte-Carlo simulation. Also, we investigate the performance against the turbulence of the salty water, air bubbles level (BL), temperature gradients (TG), shadowing parameters, and satellite pointing errors due to satellite motion, even if the beam is pointed at the center of the directive antenna relay, the beam will randomly oscillate. Finally, we contrast our approach with the conventional orthogonal multiple access (OMA) scheme to demonstrate its superiority.INDEX TERMS Satellite, underwater optical wireless communication, non-orthogonal multiple access, outage probability.
