“…On the other hand, various multiplexing schemes, such as wavelength division multiplexing (WDM) [20,21], polarization division multiplexing (PDM) [22][23][24], and mode division multiplexing (MDM) [25,26], have been proposed to enhance channel capacity in optical wireless communication. Among these, PDM has emerged as a valuable technique for optical communication systems, offering several advantages [27]. It enhances capacity, robustness, and signal quality by leveraging polarization diversity.…”

The majority of the Earth’s surface is covered by water, with oceans holding approximately 97% of this water and serving as the lifeblood of our planet. These oceans are essential for various purposes, including transportation, sustenance, and communication. However, establishing effective communication networks between the numerous sub-islands present in many parts of the world poses significant challenges. Underwater optical wireless communication, or UWOC, can indeed be an excellent solution to provide seamless connectivity underwater. UWOC holds immense significance due to its ability to transmit data at high rates, low latency, and enhanced security. In this work, we propose polarization division multiplexing-based UWOC system under the impact of salinity with an on–off keying (OOK) modulation format. The proposed system aims to establish high-speed network connectivity between underwater divers/submarines in oceans at different salinity levels. The numerical simulation results demonstrate the effectiveness of our proposed system with a 2 Gbps data rate up to 10.5 m range in freshwater and up to 1.8 m in oceanic waters with salinity up to 35 ppt. Successful transmission of high-speed data is reported in underwater optical wireless communication, especially where salinity impact is higher.

“…When the detection and control accuracy requirements are not high, nonlinear compensation can usually not are used. With the improvement of production process detection and control accuracy requirements, some original nonlinear problems are exposed, and some new systems require higher accuracy requirements [18]. Therefore, nonlinear compensation becomes more and more important.…”

The research on the nonlinear vibration compensation method in the field of forging hydraulic press is still in the blank stage. This paper studies the nonlinear vibration compensation problem of forging hydraulic press under the action of a kind of nonlinear external system and realizes the increase of a kind of nonlinear vibration in the nonlinear system of a hydraulic press. This paper proposes two methods to solve the nonlinear relationship. One is to concatenate an inverse function of a nonlinear relationship and synthesize it to obtain a linear relationship. While another is to acknowledge its nonlinear relationship and determine its output based on its nonlinear relationship. Furthermore, this paper chooses the tabu search algorithm to solve the compensation problem of nonlinear vibration and improves its search neighborhood to solve the problem of vibration range selection, analyses the vibration reinforcement calculation, and describes the specific steps of applying the tabu search algorithm. Finally, MATLAB is used to simulate and validate the designed method. The simulation results show that the method can suppress nonlinear vibration and the corresponding compensation effectiveness, proving the design method’s rationality.

“…In order to improve the transmission rate, bandwidth and reliability of a communication systems, researchers are always searching for new communication technologies and solutions. In recent years, relevant researchers have proposed a variety of solutions, such as wavelength division multiplexing (WDM), polarization division multiplexing (PDM), frequency division multiplexing (FDM), and time division multiplexing (TDM) [1][2][3][4]. However, due to the influences of Shannon limits and nonlinearity, these solutions cannot further improve channel capacity [5].…”

In this paper, a two-layer seven-core structural fiber (TLSCSF) is proposed to support and improve the propagation of more orbital angular momentum (OAM) mode beams, thus increasing the transmission capacity and spectrum efficiency (SE) of an optical communication system. The TLSCSF is composed of seven sub-cores, each containing two inner and outer layers of core rings and a central air hole. The two core rings are prepared using two materials with different doping concentrations. The supported OAM modes can be propagated in the fiber core ring. A finite element method (FEM) is used to analyze the designed fiber, and the calculated results show that the TLSCSF can stably transmit 322 OAM modes without higher order radial modes in the wavelength range of 1.5~1.6 um. The corresponding effective refractive index difference between two adjacent vector modes (HE/EH) is more than 10-4. The measured effective mode areas (Aeff) and the confinement losses (CL) of HE or EH modes are larger than 54 um2 and smaller than 10-10 dB/m, respectively. Moreover, the calculated dispersion variations and the mode qualities are lower than 230 ps/nm/km and more than 90%, respectively. Finally, the 10ps walk-off lengths of all vector modes supported by TLSCSF at a wavelength of 1.55 um are also evaluated, where the measured results show that except for HE2,1 and EH1,1, all other modes achieve a 10ps walk-off length of the order of 103 to 105. Consequently, the TLSCSF can contributes to improving the channel capacity and SE by supporting 322 fundamental radial OAM modes with robust performances in an optical communication system.
