Despite their multitude of benefits, free-space optical (FSO) communication systems experience severe performance degradation due to the diverse atmospheric conditions commonly present in their deployment areas. Optical signals transmitted through the atmosphere are subject to substantial scintillation losses caused by fluctuations in the refractiv...
This study introduces a new design for an ultra-compact shared-aperture antenna utilizing a quarter-mode substrate integrated waveguide (QMSIW) cavity. The proposed antenna operates as a 4 × 4 multi-input multi-output (MIMO) system in three 5G/6G millimeter-wave (MMw) bands, while functioning as a single element antenna for a 5.5 GHz wireless fidel...
This paper discusses the throughput of a fifth generation (5G) new radio (NR) system. The main goal of this research is to provide and develop a pathway for improving the throughput in the 5G system by investigating and controlling certain effective factors. The studied factors in this paper are the used modulation technique, the used subcarrier sp...
In this paper, an interaction between multimode graded-index optical fiber parameters with crosstalk and spatial shift in Wavelength Division Multiplexing (WDM) technique is presented. Pulse spreading caused by linear effects in optical fiber due to dispersion is considered in this proposed system. Results show how channel spacing, fiber core radiu...
Cryptography is used for secured data transmission, but the resulted unreadable messages usually attract others attention, so steganography is employed to hide the secret information to prevent attacker from discovering the presence of secret data. This paper proposes an improved technique that combines both Advanced Encryption Standard (AES) algo...
Channel coding is an essential requirement for digital communication systems, particularly for underwater acoustic channels, to perform accurately and reliably in the presence of ambient noise, absorption loss, interference, and much other impairment. Low complexity encoding and decoding algorithms are investigated i.e. order statistic decoding (OS...
This paper presents performance evaluation of differential quadrature phase shift keying (DQPSK) transmission over underwater acoustic channel (UWA). In this paper, a channel model that simulates the multipath fading characteristics of the shallow underwater channel is carried out in order to make possible of performance evaluation of DQPSK transmi...
This paper presents the effects of the input signal on the gain and carrier density response of a semiconductor optical amplifier (SOA). The SOA is modeled using a segmentation method. The input bias current input power, wavelength and the length of SOA required for amplification and switching functions are investigated. Moreover, the effect of tem...
The significance of this work is to exploit the advantage of longitudinal mode selectivity with asymmetrical construction of two laser cavities. Yet, the mode selectivity results from two sections laser structure can be used in biological cell imaging application where the cell can be detected if passed through. Therefore, a simulation is carried o...
In this study, a performance evaluation of radio over multimode fibre system using coded orthogonal frequency division multiplexing (COFDM) is presented. The performance analyses based on bit-error ratio (BER) are extensively investigated. In addition, the effect of fibre length on BER performance is presented. Moreover, the effect of the exponent...
In this paper, a performance evaluation of radio over multimode fibre system (ROMMF) using Coded orthogonal frequency division multiplexing (COFDM) is presented. The performance analyses based on bit-error ratio (BER) are extensively investigated. In addition, the effect of fibre length on BER performance is presented. Moreover, the effect of the e...
This study introduces an accurate non-linear distortion analysis for vertical cavity surface emitting lasers (VCSELs) based on Volterra series approach in directly modulated scheme. Closed-form expressions of the optical response of VCSELs in terms of modulation response, harmonic distortions, and second- and third-order intermodulation distortions...
In this letter, an accurate nonlinear Volterra series analysis for vertical-cavity surface-emitting lasers (VCSELs) is presented. Closed-form expressions for the modulation response, harmonic distortions, and second- and third-order intermodulation distortions are derived. Moreover, the suggested nonlinear model avoids the numerical solution of las...
This paper presents a complete experimental low-cost downlink setup for the transmission of QPSK-COFDM signal over standard graded index multimode fiber. Moreover, many parameters are assessed in detail such as the effect of the fiber lengths, RMS delay spread, link gain, noise figure and AM-AM/AM-PM to investigate the link performance. This experi...
