Research ArticleOpen accessIn the abstractDesign of Field Programmable Gate Array Based Emulators for Motor Control ApplicationsAhmed Ben Achballah, Slim Ben Othman, Slim Ben SaoudProblem statement: Field Programmable Gate Array (FPGA) circuits play a significant role in major recent embedded process control designs. However, exploiting these platforms requires deep hardware conception skills and remains an important time consuming stage in a design flow. High Level Synthesis technique avoids this bottleneck and increases design productivity as witnessed by industry specialists. Approach: This study proposes to … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 12 Jun 2012 · 8,726 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Novel Structure SIW 90° CouplerAbdelkhalek Nasri, Hassen Zairi, Ali GharsallahThis paper focuses on the analysis of passive devices using a recent emerging technology named Substrate Integrated Waveguide (SIW). This technology has been used in the conception of planar compact components for the microwave and millimeter wave’s applications. Through using Ansoft HFSS and CST code a substrate integrated waveguide coupler has conceived and optimized in this study. The SIW 90° … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 16 Mar 2016 · 7,909 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmbedded Software Platform Used for Detection and Mitigation of a MAC Anomaly in IEEE 802.11n NetworksArgemiro Bevilacqua, Vitor Chaves de Oliveira, Gunnar Bedicks Jr. et al.IEEE 802.11 standard is largely used anywhere as a cheap way to access internet, but the majority of devices used does not provide a standard way to manage them. Mobile stations competing for access point may causes a general wireless network failure, known as the ''MAC Anomaly''. It is presented here an access point with modified firmware, that monitors wireless … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 21 Nov 2015 · 6,517 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoftware Defined Radio Implementation of a QPSK Modulator/Demodulator in an Extensive Hardware Platform Based on FPGAs Xilinx ZYNQSérgio Bimbi Junior, Vitor Chaves de Oliveira, Gunnar Bedicks JuniorSoftware Defined Radio (SDR) technology enables wireless devices deployment with support to multiple interfaces in modulation formats and it has gained importance due to the current wireless standards proliferation. In order to activate these functionalities it is necessary to apply SDR inside a reconfigurable hardware such as the Field Programmable Gate Array (FPGA). In this study, design procedures developments are … …Journal of Computer Science, Vol. 11, Issue 4 · 2 Jun 2015 · 8,818 accessesView PDFCite
