Research ArticleOpen accessEvery word in the titleA Preamble-Based Frequency Offset Compensation Scheme in Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing SystemsElnaz Ershadi, Hamidreza BakhshiProblem statement: Combining the properties of Multiple Input Multiple Output (MIMO) systems with those of Orthogonal Frequency Division Multiplexing (OFDM), MIMO-OFDM was considered to be a promising technique in the future of wireless communications. However, its sensitivity to frequency offsets which results in Inter-Carrier Interferences (ICIs) makes it necessary to use an exact frequency offset estimation method for data recovery … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 7,570 accessesView PDF Cite

EditorialOpen accessIn the abstractChoice Meaning and Context: Two Sides of the Same Coin?Saadettin Sel, Joachim Storsberg, Mark A. Brown, Christian SchmidtThe human intellect is a powerful instrument to be applied to problems. Expressed differently, sharpening one’s acumen by regular exposure to conundra can be likened to exercising a muscle or refining a tool such as creating brushes to suit certain tasks. Such applications hinge on a reasonable understanding of a given problem and the presentation of opposing viewpoints of the … …American Journal of Immunology, Vol. 13, Issue 2 · 24 May 2017 · 6,923 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOrthogonal Frequency Division Multiplexing Timing Synchronization in Multi-Band Orthogonal Frequency Division Multiplexing Ultra-Wideband SystemsAymen M. Karim, Md. Shabiul Islam, Masuri OthmanProblem statement: MB-OFDM UWB systems have attractive features and received a great attention. It has the capability of sending/receiving data at rates in access of 100 Mbits sec-1. Owing to the sensitivity of OFDM systems to synchronization errors, a fast synchronization algorithm is required to discern for the start of OFDM symbol. Existing approaches to OFDM time synchronization rely on … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,422 accessesView PDF Cite
