Various microstrip patch and slot antennas fed by a feed line designed on a 2.2 permittivity Rogers Duriod substrate are considerably studied and comprehensively analyzed as new and authentic new design approaches antennas. The antennas have been designed using the 3D EM High Frequency Structure Simulator (HFSS) V11. The microstrip patch (MSPA) design 1 provides a total antenna gain of 1.87 dBi, a return loss (S11) of −5.5 dB. while the micro strip patch slot antenna (MSPSA) design 2 have achieved a total antenna gain of 6.017 dBi and a return loss (S11) of −23.8 dB at 865 MHz for 60 mm patch length. The other micro strip patch slot antennas (MSPSA) designs have achieved a total antenna gain of 5.92 dBi, 4.48 dBi and at S11 12 dB, 6.87 dB respectively. Modeling and optimization of the one slot MSPSA design 2 have produced the most optimized results hence the MSPSA design 2 is an attractive antenna solution for RFID applications.","PeriodicalId":325063,"journal":{"name":"CCECE 2010","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114070118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At each symbol interval, a primary data estimate is made based on the constrained linear minimum mean square error (MMSE) criterion, and this is used by the subsequent channel estimation. As a result, unlike the known Kalman-based tracking algorithm, there is no delay between the channel estimation and the channel estimates needed for the current equalizer adaptation. The performance is evaluated by simulation, allowing fair comparison with: the benchmark of equalized, coherent detection; a known blind system based on Kalman filtering which employs channel tracking with delay; and for the flat fading case, an optimized pilot symbol assisted modulation (PSAM) system.","PeriodicalId":325063,"journal":{"name":"CCECE 2010","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123855416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Liveness tests complement biometric systems by introducing an extra level of authentication to prevent identity forgeries. In this abstract we present the fundamental ideas behind a new authentication paradigm that captures the individual's unique signature by measuring unconsciously motivated mistakes or actions. The robustness of our system relies on the hypothesis that each individual possesses behavioural characteristics that are brought about by some unique traits (i.e. how information is processed, categorized and accessed) that are not consciously accessible to the individual and can be measured as that individual's unique behavioural signature. We will refer to this unconsciously motivated behavioural signature as the unconsciousness signature. An implicit result includes the use of our proposed system as a liveness detection mechanism. Here we describe our hypotheses and provide a rationale that indicates their suitability for further studies as a new authentication paradigm.","PeriodicalId":325063,"journal":{"name":"CCECE 2010","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123951365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
