Research ArticleOpen accessAll words, across the recordMulti-Threshold based Scheduling for Multi-User Multiple-Input Multiple-Output SystemsK. Chanthirasekaran, M. A. BhagyaveniProblem statement: Multi-User Multi-Input Multi-Output (MU-MIMO) system had eventually used in 4th generation wireless networks either to achieved diversity gain or multiplexing gain. Many recent scheduling addresses the threshold based resource allocation where in resource were not utilized properly. Approach: In this study a new Multi Threshold Based Channel Aware Scheduling (MTCAS) was proposed for performance improvement and proper resource … …Journal of Computer Science, Vol. 8, Issue 7 · 21 Jun 2012 · 6,948 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordErgodic Capacity Analysis of Multiple Input Multiple Output Systems with Dual Hop Amplify and Forward Relay NetworksC. Poongodi, A. ShanmugamProblem Statement: In MIMO system, capacity mainly depends on the channel and the antenna characteristics. The capacity can be improved by proper design of antenna elements and choosing appropriate array configuration and the directive elements give more capacity than omni directional elements. The dual polarized antennas are better than single polarized antennas as the former can provide two information channels. … …Journal of Computer Science, Vol. 7, Issue 12 · 17 Oct 2011 · 6,745 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordBoarding School Students Monitoring Systems (E-ID) Using Radio Frequency IdentificationHerdawatie Bt Abdul Kadir, Mohd Helmy Abd. Wahab, Siti Nurul Aqmariah Bt Mohd KanafiahProblem statement: Monitoring Boarding school student movement using the old-fashioned study system is inefficient and brings difficulty to the hostel management to check attendance manually. By using RFID technology, student movement is quick and easy. Approach: The application of RFID Matrix Card system as a boarding school students monitoring system (E-ID) were purposed to improve school management system and to … …Journal of Social Sciences, Vol. 5, Issue 3 · 30 Sep 2009 · 9,122 accessesView PDF Cite
