Research ArticleOpen accessIn the abstractA Novel Modulation Technique for 5G Mobile Communication SystemArun Kumar, Manisha GuptaBy the year 2020, the data traffic can be approximately increase by 30%, which cannot support by existing mobile technologies. Hence, there is a requirement of next generation wireless communication (5G) which aim to provide a high capacity, data-rate at the speed of 1Tbps. By selecting a better modulation technology, the required capacity and data-rate can be achieved. In this … …American Journal of Applied Sciences, Vol. 12, Issue 9 · 28 Sep 2015 · 7,652 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpectrum Switchover for Commercial use and "Spectrum Procurement" ContestAlexander RymanovMotivated by the need to implement wireless broadband mobile communications (Long Term Evolution (LTE)) in the "Digital Dividend" band (790-862 MHz) in Russia and to relocate government users of spectrum, especially the Aeronautical Radio Navigation Service (ARNS), this article focuses on the funding of organizational and technical measures to relocate government users from the spectrum and to transfer the spectrum … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 10 Dec 2014 · 6,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractREDUCING 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
