Research ArticleOpen accessIn the keywordsREDUCING TRANSMITTED POWER OF MOVING RELAY NODE IN LONG-TERM EVOLUTION-ADVANCED CELLULAR NETWORKSJaafar A. Aldhaibani, A. Yahya, R. B. Ahmad et al.Wireless multi-hop relay networks have become very significant technologies in mobile communications. These networks ensure data rate transfer and coverage extension with a low cost. In this study two types of relay are studied; Fixed Relay Node (FRN) and Moving Relay Node (MRN). Where system analyses for uplink and downlink transmission are derived in this study. Moreover the optimal relay … …Journal of Computer Science, Vol. 10, Issue 6 · 3 Feb 2014 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Approach for Sub-Channels Assignment in Downlink Fourth Generation Mobile SystemsFakhreddine Khelifa, Abdelaziz SametProblem statement: We proposed a new heuristic method for subchannels allocation problem in the context. Approach: In this system, OFDM transmission method has been used, in order to reduce the effect of multipath fading, OFDMA to achieve multiple access schemes and flexibility in resource allocation. Results: An adaptive method for subchannels allocation is necessary in order to exploit the multiuser … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 6,588 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing Telecommunication Network Management with Autonomous Optimization Agents and Machine LearningDanny Adil Sibarani, Evaristus Didik MadyatmadjaThis study explores the integration of Machine Learning (ML) and Autonomous Optimization Agents (AOAs) in the management and optimization of Radio Access Networks (RAN). The research addresses the growing challenges posed by the need for skilled network experts capable of managing and analyzing large-scale network data, including Key Performance Indicators (KPIs) and thousands of network configuration parameters. To overcome these … …Journal of Computer Science, Vol. 21, Issue 2 · 4 Mar 2025 · 7,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Interference Mitigation Techniques in 4G Networks in Mobile EnvironmentsEmna Hajlaoui, Abdelhakim Khlifi, Samia Dardouri et al.Intercell Interference (ICI) is one of the major factors that limit the performance and Quality of Service (QoS) of 4G wireless networks (Long Term Evolution/LTE-Advanced). For this reason, heterogeneous networks present an attractive solution for the improvement of mobile network’s services to provide better data rates and coverage. So, a key scheme in 4G traffic processing is the interference mitigation … …Journal of Computer Science, Vol. 15, Issue 12 · 25 Dec 2019 · 7,317 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Channel Equalization Using Multiplicative Neural Network for Rayleigh Faded ChannelP. Sivakumar, N. Chithra, S. N. Sivanandam, M. RajaramProblem statement: Digital transmission over band-limited communication channel largely suffers from ISIS and various noise sources. The presence of ISI and noise causes bit errors in the received signal. Equalization is necessary at the receiver to overcome these channel impairment to recover the original transmitted sequence. Traditionally equalization is considered as equivalent to inverse filtering and implemented using linear-perform under … …Journal of Computer Science, Vol. 7, Issue 11 · 18 Aug 2011 · 6,931 accessesView PDFCite
Research ArticleOpen accessIn the abstractLEUKOTRIENE C4 SYNTHASE AND LEUKOTRIENE RECEPTOR-1 GENES POLYMORPHISM AMONG ATOPIC ASTHMATIC PATIENTSHeba M. Kadry, Amal H. Atta, Mostafa K. Sultan, Nagwa A. El-BazAsthma is a complex polygenic disease in which Cysteinyl Leukotrienes (Cys-LTs) are a potential risk factors causing airway inflammation and remodeling, which are characteristics of asthma. The polymorphisms in the leukotriene C4 synthase -444A/C and cysteinyl leukotriene receptor1 927 T/C genes has been implicated in susceptibility to asthma. The objective of this study was to analyse two different polymorphisms, LTC4S-444 … …American Journal of Immunology, Vol. 10, Issue 2 · 5 May 2014 · 7,379 accessesView PDFCite
