Summary: Intelligent reflecting surfaces (IRS) offer significant enhancement in the reliability of underwater optical wireless communication (OWC) systems under attenuation, beam displacement, and turbulence effects. The combination of a large number of reflecting surfaces and a larger aperture diameter yields a more noticeable improvement. This study quantifies the performance enhancement offered by the integration of IRS technology in the context of underwater OWC, considering factors such as underwater attenuation, pointing error, and turbulence effects.

Summary: Underwater wireless communication technology is important for marine environment monitoring and ecological protection. Underwater optical wireless communications have advantages of long transmission distance, high rate, low power consumption, and strong anti-interference ability. However, there are issues of unstable transmission and limited communication distance. This paper establishes a model of ocean turbulence channels and studies the transmission characteristics of orbital angular momentum light. The polarization coding technique is applied to extend the communication distance and reduce the system bit error rate.

Summary: This paper investigates the spectral efficiency (SE) and energy efficiency (EE) of asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) for visible light communication (VLC). Optimal power allocation schemes are proposed to maximize SE and tackle the non-convex EE maximization problems. The performance of the proposed schemes is validated through numerical analysis.

Summary: This paper analyzes a combination of hybrid triple hop terrestrial free-space optical (FSO), fiber optic cable (FOC), and underwater optical wireless communication (UOWC) for high-speed optical connectivity between onshore and submerge systems. The performance of the UOWC link is improved using a bend-insensitive intermediate FOC link and spatial diversity. Different transmission signaling schemes are employed to evaluate system performance. Results show that MISO-OOK-RC performs better in higher signal-to-noise ratio conditions.

Summary: The proposed superposed 64QAM constellation scheme utilizes two geometrically shaped 8QAM constellations to reduce peak-to-average power ratio and minimize the risk of nonlinear distortion in 2 x 2 MIMO VLC systems. Experimental results show improved bit error rate performance compared to traditional schemes, with a dynamic range improvement in driving peak-to-peak voltages of LEDs when optimal power ratio is achieved.

Summary: Visible light communication, a controversial technology, is increasingly promising in wireless networks, particularly for indoor and outdoor applications. This article suggests VLC methods and architectures that offer high security in vehicle communication and interactions with the environment or other cars. These proposed architectures involve incorporating ambient lighting equipment and systems, as well as indoor and outdoor lighting systems. Strengthening VLC's position relies on securing data within vehicular networks through multiple layers of filtering at the PHY level, which serves as the primary means of direct contact with other entities in the network. The practical steps taken in the research process demonstrate the viability of the evaluations and proposals presented, warranting future consideration.

Summary: Underwater wireless optical communication (UWOC) is useful for transmitting data short distances in the ocean. Special requirements and design criteria are needed to eliminate noise caused by the use of LED as an illuminant. Simulation and analysis demonstrate that the wavelength of UWOC should be shorter than that of the LED illuminant, and the spectrum width of the communication signal and the optical filter should be wider to effectively eliminate noise.
