Research ArticleOpen accessIn the keywordsFrequency Extended-MUSIC Method for DOA Estimation in Indoor IR-UWB EnvironmentHajer Meknessi, Ferid Harrabi, Ali GharsallahIn recent years, many researchers have been developed in order to ensure an accurate localization. So many techniques have been used the direction of arrival to estimate and track of IR-UWB signals. In this study, we propose a new direction of arrival estimation method for impulse radio UWB signals. This technique based on Extended-Music algorithm. The proposed method has high … …American Journal of Applied Sciences, Vol. 13, Issue 4 · 8 Apr 2016 · 7,289 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Novel Linear Array Antenna Based on UWB Slot AntennaFaten Ben Ghenaya, Ridha Ghayoula, Ali GharsallahThis paper introduces the novel Ultra-Wide Band (UWB) antennas for UWB applications. We used two different structures, the first is fed by micro-strip line and the second is a compact coplanar waveguide fed planar slot antenna. These designs are a small on planar antenna. The substrate used is FR4 that have the characteristics following: Permittivity εr = 4.4 Impulse Radio … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 25 Mar 2016 · 7,434 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImpulse Radio Ultra Wide Band Based Mobile Adhoc Network Routing Performance AnalysisM. Sreedhar, C. VenkateshThis study presents with the routing overhead analysis of impulse radio - Ultra Wide Band based wireless networks which Employs Dynamic Nature Routing (EDNR) method for determining and selecting the stable route in Mobile Adhoc Network (MANET). This method requires only two sample packets and uses piggyback information on Route-Request (RREQ) and Route-Reply (RREP) packets during a route-discovery procedure. Conventional … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 15 Apr 2013 · 5,891 accessesView PDF Cite
