Research ArticleOpen accessIn the abstractAcoustic Echo Cancellation: Dual Architecture ImplementationB. Stark, B. D. BarkanaProblem statement: With the rise in mobile communication, it is becoming more frequent to use a communication device in an enclosed noisy environment, such as a subway or in a lobby. In this setting however, the received microphone is severely degraded by the echo from the speaker and background noise. The audio processing necessary to clarify the desired speech can … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,392 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal-Time Data Capture Model for Accelerated Payment of Small-Scale FarmersNatasha Mwansa, Jackson PhiriMost developing countries especially in Africa face a number of challenges in the area of food security. These challenges include proliferation, theft, poor inventory system, poor transport and communication network. Zambia is one of the countries with these challenges and has been losing millions of dollars each year due to various challenges in managing the inventory system. In this paper, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 29 Sep 2018 · 7,105 accessesView PDFCite
Research ArticleOpen accessIn the abstractINTELLISENSE CLUSTER MANAGEMENT AND ENERGY EFFICIENT ROUTING IN MOBILE AD HOC NETWORKSSangeetha Kuppusamy, Natarajan MathaiyanMobile Ad Hoc Network (MANET) is a collection of distributed nodes which communicate using multi-hop wireless links with frequent node mobility. The aim for ad hoc networks is to accommodate light-weight weight, battery supercharged transportable devices. Due to the restricted power, we've to vogue economical ways in which to use the current power. For a networking device, vital power is … …Journal of Computer Science, Vol. 9, Issue 9 · 6 Aug 2013 · 6,371 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractReduction of PAPR by Using Clipping and Filtering for Different Modulation SchemesArun Kumar, Manisha GuptaOrthogonal Frequency Division Multiplexing (OFDM) is one of the most advanced technologies for high speed data access in mobile communication. It’s significantly increases the capacity, data-rate etc. but one of its disadvantage is high Peak Average Power Ratio (PAPR) which reduce the performance of transmitter amplifier. In this study, PAPR is reduced by using a clipping and filtering technique for … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 13 Feb 2016 · 8,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial Representation to Support Visual Impaired PeopleAbbas Mohamad Ali, Shareef Maulod ShareefThe rapid development of Information and Communication Technology (ICT) enhances the government services to its citizen. As a consequence affects the exchange of information between citizen and government. However, some groups can experience some difficulties accessing the government services due to disabilities, such as blind people as well as material and geographical constraints. This paper aims to introduce a novel … …Journal of Computer Science, Vol. 11, Issue 3 · 15 Apr 2015 · 6,198 accessesView PDFCite

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 PDFCite
