    (American Institute of Physics Inc., 2023) Almetwali, Abdullah S.; Bayat, Oguz; Abdulwahid, Maan M.; Mohamadwasel, Noorulden Basil
    The establishment of 5G networks launched before few years and is projected to bring about significant changes in people's daily lives, which connect nodes using optical transceiver modules and optical fibers. The connection between the Central and Base Stations is the most intriguing part of the 5G network, and many academics have examined it extensively in order to improve and maximize network efficiency and achieving the highest data rate with less complexity, and cost-effectiveness. As a result, this paper has been used the Optisystem program and a Dense Wavelength Division Multiplexing (DWDM) Radio over Fiber (RoF) approach to demonstrate, plan, and execute in this article. For higher-speed transmission systems targeted toward Tbps connectivity, a 50 by 40 Gbps data transmission system is proposed. Channels 1, 4, 8, ., 48, and 50 were chosen as samples for the investigation. The output analysis was based on the eye-opening parameters, Quality Factor (QF), and Min Bit Error Rate (MBER) for the distances ranging between (60-180) Km. The results showed a higher data rate performance for the proposed system to reach 2 Tbps for future applications. Furthermore, QF parameters showed encourage results as the averaged obtained values were above the threshold by ranging between (0.22-13) dBm. © 2023 Author(s).

    Implementation of two polarization DQPSK WDM Is-OWC system with different precoding schemes for long-reach GEO Inter Satellite Link
    (Institution of Engineering and Technology, 2023) Abdulwahid, Maan M.; Kurnaz, Sefer
    The advantages of optical wireless communication in space are its fast speed, large capacity, lack of ElectroMagnetic Interference (EMI), high level of security, and broad bandwidth. OWC offers an advantage over microwave communication because the relay function in laser-based communication reduces system time. To achieve the long distances required for Geostationary Earth Orbit (GEO) communication, this paper designs and implements an 8-channel, Dual Polarization Differential Quadratic Phase Shift Keying (DP-DQPSK) Wavelength Division Multiplexing (WDM) system for inter-satellite optical wireless communication (Is-OWC). The system was built to accommodate 240 Gbps overall, and 30 Gbps in each channel, and the investigated transmission lengths were between (10,000 km to 48,000 km). Additionally, two precoding schemes were included in the investigation of the proposed system. To evaluate the system's performance, Quality Factor (QF), Log of Bit Error Rate (BER), and receiver sensitivity metrics will be examined to evaluate the performance of the proposed system. Such findings show that the proposed system, when utilizing a DPSK precoder, may accomplish reliable transmission across 40,000 km. In addition, the Duobinary precoder may be used for transmissions of up to 20,000 kilometers with higher performance when compared to the DPSK scheme. Furthermore, Duobinary improves the average QF by (7) dB and (0.92) dB, and receiver sensitivity by (-7.93) dB and (-3.28) dB at distances of 10,000 km and 20,000 km, respectively. In the future, numerous division multiplexing techniques may be utilized to boost the effect of the transferred data rate to fulfill modern satellite applications.

    The channel WDM system incorporates of Optical Wireless Communication (OWC) hybrid MDM-PDM for higher capacity (LEO-GEO) inter satellite link
    (Elsevier GmbH, 2023) Abdulwahid, Maan M.; Kurnaz, Sefer
    The rising demand for exponential growth in data rate and effectiveness of satellite communication systems has drawn the attention of several researchers recently. The Inter Satellite OWC (Is-OWC) technology, which combines Optical Wireless Communication (OWC) and Inter Satellite Link (ISL), is critical for achieving high data rate transport around the world. The challenge in ISL's transmission range is limited for a variety of reasons, including the appropriate modulation format, pointing error, and space turbulence. As a result, this paper designs and implements a high-capacity 8-channel Wavelength Division Multiplexing (WDM) system that uses the Orthogonal Frequency Division Multiplexing (OFDM) technique to support high data rates by implementing multiple low-data rate subcarriers and achieves high tolerance to dispersion and Inter Symbol Interference (ISI). Additionally, by using a hybrid scheme for Mode Division Multiplexing (MDM) and Polarization Division Multiplexing (PDM) for cost-effectiveness requirements and transmit eight independent channels over a 48,000 km Is-OWC link. Each channel is capable of carrying 320 Gbps of data rate, and by using the novel hybrid MDM-PDM scheme, the data rate for each channel is raised to 640 Gbps. The simulation analysis achieved a maximum data rate of 5.12 Tbps using the 8-channel Is-OWC WDM OFDM. The maximum distance achieved was 48,000 km at a log BER of − 3.1101 and the average received power of − 70.14 dBm. The proposed system shall prop the transfer of high data rates and meet the requirements for reliable satellite connectivity links.

    The utilization of different AI methods-based satellite communications: a survey
    (American Institute of Physics, 2024) Abdulwahid, Maan M.; Kurnaz, Sefer
    The potential for service continuity across uncovered and under-covered regions, service ubiquity, and service scalability are all offered by Satellite Communication (SC) for the recent decade. However, to take advantage of these benefits, it is necessary to address several obstacles first. This is because the management of resource, control and security of network, the efficient utilization of spectrum, and efficient utilization of satellite-based communication networks are more difficult to accomplish than those of Terrestrial Networks (TNs). Thereby, Artificial Intelligence (AI), which encompasses Machine Learning (ML), Deep Learning (DL), and Reinforcement Learning (RL), has been continuously expanding as an area of study and has shown good outcomes in a variety of applications, including wireless communication. As a consequence of this, several publications put forth a variety of algorithmic solutions to the problem involving the management of various applications for SCs. Such an algorithm will employ various DL methods to improve the effectiveness of SCs. As a consequence of this, the aim of this paper is to provide an exhaustive overview of the utilization of various AI methods for a broad aspect of SCs. Following this, a general overview of the most recent details related to various AI methods and their related classifications will be presented. In addition, the study provides a summary of the many bodies of research that apply AI-based approaches to the resolution of satellite-related problems. In addition to this, AI may also be used to spot trends in satellite traffic and utilize bandwidth more effectively, making better use of the resources.
