Research ArticleOpen accessIn the keywordsHIGH IMPEDANCE SURFACES FOR FLEXIBLE AND CONFORMAL WIRELESS SYSTEMSHaider R. Khaleel, Hussain M. Al-Rizzo, Ayman Issac, Said AbushamlehRecent years have witnessed a great deal of interest from both scientific and academic communities in the field of flexible electronic systems. Most flexible electronic systems require the integration of flexible antennas operating in specific frequency bands to provide wireless connectivity which is highly demanded by today’s network oriented society. On the other hand, High Impedance Surfaces have become very … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 2 · 26 Jun 2014 · 7,218 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEnsuring Multi Messages Broadcasting in Mobile Ad Hoc Network using Network Coding ApproachS. V.M.G. Bavithiraja, R. RadhakrishnanProblem statement: In mobile adhoc network, broadcasting is a common operation for route establishment and for sending control and emergency messages. Most of the existing broadcasting algorithms consider broadcasting from single source node and consider only single message broadcasting. Initiating multiple messages broadcasting from multiple sources is a challenging task which requires minimum number of retransmission made by the forwarding … …Journal of Computer Science, Vol. 8, Issue 6 · 17 Mar 2012 · 7,055 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Comparative Performance Analysis of Multiple-Input Multiple-Output using MATLAB with Zero Forcing and Minimum Mean Square Error EqualizersBara'u Gafai Najashi, Tan XiaohengProblem statement: Multiple-Input Multiple-Output systems (MIMO) were regarded as one of the most promising technologies in field of wireless communication. Generally considered as one of the several forms of smart antenna technology, it offers considerable increase in data throughput and link range without additional bandwidth or transmit power. The general idea involves the use of several antennas at the transmitter … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 29 Nov 2011 · 8,298 accessesView PDFCite
Research ArticleOpen accessIn the keywordsKoch Curves: Rewriting System, Geometry and ApplicationMamta Rani, Riaz Ul Haq, Norrozila SulaimanProblem statement: Recently, new Koch curves have been generated by dividing the initiator into three unequal parts. There is no formal rewriting system to generate such kind of curves. Approach: It is required to measure the new changed geometrical properties. Generalized rewriting systems for the new Koch curves have been developed. Results: New formulas have been given to measure their … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 7,065 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRadiation Measurement from Mobile Base Stations at a University Campus in MalaysiaMd. Rafiqul Islam, Othman O. Khalifa, Liakot Ali et al.The tremendous growth of telecommunication industry results the number of hand phone users increases everyday. In order to support the growing number of users, the mobile base stations can be seen in almost everywhere. This scenario has created uncomfortable feelings to the people that they may be affected by the radiations from antennas. A measurement was done at student hostels … …American Journal of Applied Sciences, Vol. 3, Issue 4 · 30 Aug 2006 · 7,290 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPerformance Analysis of Multi-user Multi Input Multi Output- Interleave-Division Multiple-Access System Employing Turbo Coding with Multi-User Detection over Frequency-Selective Wireless Communication ChannelKuttathatti Srinivasan Vishvaksenan, R. Seshasayanan, Yuvaraj KrishnamoorthyProblem statement: This study presents the performance analysis of multi-user Multi Input Multi Output (MIMO) assisted interleave based multiple-access system. In IDMA, different interleavers are used to distinguish users as against different signature sequence in a conventional code-Division Multiple-Access (CDMA) scheme. Approach: The basic principle of IDMA is that the interleaver is unique for the users. Results: In this study, … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 6,881 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAN EXTENDED METHOD FOR STUDING CYLINDRIC STRUCTURE BY USING ITERATIVE METHODS. Beldi, R. Bedira, A. GharsallahThe method iterative Wave Concept Iterative method Procedure (WCIP) avoids the undesired phenomenon of unbounded operators; relations between currents and fields, obtained using unbounded impedance operators, are transposed to relations between waves, supplied by bounded scattering operators. …American Journal of Applied Sciences, Vol. 11, Issue 8 · 27 Jun 2014 · 6,434 accessesView PDFCite
