Research ArticleOpen accessIn the keywordsEnergy Efficiency Analysis of a TR-UWB SystemAdil El Abboubi, Fouzia Elbahhar, Marc Heddebaut et al.In wireless communications, where sensors operate on batteries, the energy consumption must be reduced while considering the communication range and data rate requirements. In this context we analyze and compare, in this study, the UWB and TR-UWB system in terms of the total energy consumption. So, for that, we develop an analytical model to estimate the energy consumption of a … …Journal of Computer Science, Vol. 12, Issue 1 · 15 Feb 2016 · 7,321 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNEURO FUZZY BASED PERFORMANCE ANALYSIS OF MULTIBAND ULTRA WIDE BAND ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEMG. Joselin Retna Kumar, K. S. ShajiThis study proposes an efficient channel-estimation scheme for Multiband (MB) Orthogonal Frequency Division Multiplexing (OFDM)-based Ultra Wide Band (UWB) communication systems. One of the challenges in wireless system is the frequency selective fading caused due to multipath channel between the transmitter and receiver. The signal bandwidth in broad band cellular wireless systems typically exceeds the coherence bandwidth of the multipath … …Journal of Computer Science, Vol. 10, Issue 8 · 5 Mar 2014 · 6,624 accessesView PDF Cite

Research ArticleOpen accessIn the abstractANALYSIS AND SOLUTION FOR MULTI-BAND ORTHOGONAL FREQUENCY-DIVISION MULTIPLEXING ULTRA WIDE BAND SYSTEM IN REAL ENVIRONMENT FOR VEHICLE TO INFRASTRUCTURE APPLICATIONSanaa Kabil, Raja Elassali, Fouzia Elbahhar et al.Many researches in the world deal with driving on the road to ensure optimum safety. In this context, several telecommunication technologies are often used to connect the vehicles via continuous wireless communication with the infrastructure, exchange data and information relevant to increase overall road safety and enable cooperative traffic management. These systems are not reliable for all situations and the … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 7,012 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSymbol Timing Estimation in Multiband Orthogonal Frequency Division Multiplexing based Ultrawide band SystemM. N. Suresh, S. J. Thiruvengadam, V. AbhaikumarProblem statement: The Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) Based Ultra Wideband system (UWB) is highly susceptible to symbol timing error. Symbol timing estimation in MB-OFDM based UWB is difficult due to the presence of strongest path at delayed instant. Approach: Symbol timing estimation has two steps namely a coarse estimation and a fine estimation. In this study, a maximum … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 10 Feb 2012 · 7,108 accessesView PDF Cite
