The DOA estimation from objects behind walls is investigated utilizing the MUltiple SIgnal Classification (MUSIC) algorithm compensated by Extended Kalman Particle Filtering (EKPF) technique for the first time. Simulation results show that the stand-alone MUSIC algorithm fails to identify two distinct objects having close DOAs and fails to track targets when they are moving close to each other. The results also reveal that the EKPF algorithm in conjunction with MIMO nulling technique correctly identifies close and overshadowed moving objects and improves the tracking success rate.","PeriodicalId":143796,"journal":{"name":"2016 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124688867","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}

Up to 3 different UWB chipless tags designs with an amount of resonators ranging from 3 to 4 and a conductive strip width of 1 mm are fabricated. The tags are measured, its operation validated, and the performance comparisons between different fabrications are provided when available. The magnitudes of the radar cross section (RCS) calculated from the measurements of the scattering parameters, show that no major performance degradation is obtained for same tag designs fabricated with different metals and same substrate.

Simulation results show that the I-beam has different influence upon the amount power of incident on a tag antenna on its different locations along the beam. Furthermore, they show that suitably designed tag antennas can increase the power density in their locations in the inner surface of the I-beam. The measurement and simulation results are in good agreement.

An equivalent two-port circuit is derived for the receiver noise figure. Compared to the actual LNAs, the equivalent IAA is shown to have the same noise-match admittance but generally larger minimum noise figure and coefficient of source mismatch. The increased parameters are shown to be Lange constants, invariant under lossless transformations at the inputs of the actual IAAs. The increase in the l.ange constants is found to be closely determined by the power in the orthogonal response of the array when excited by a source aligned with the vector of beamforming coefficients. The representation provides a basis for comparing the performance of various array designs with differential beamforming or other beamforming eonstraints.","PeriodicalId":143796,"journal":{"name":"2016 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121490013","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}

The proposal aims to minimize power consumption with lower data rate loss. For this work, a flat fading channel is considered for exchanging signals between two wireless users separated by a specified distance. This distance is splitted by a set of bidirectional Amplify-and-Forward (AF) relay nodes that allow to amplify the input signal without any further processing. The locations of these relays are optimized first and the trade-off expression between EE and SE is then derived. All analytical expressions (i.e., optimal relay location and trade-off EE SE ) are corroborated by the simulation.","PeriodicalId":143796,"journal":{"name":"2016 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133240979","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}

These ducts can cause anomalous propagation of radio signals. The most popular method of evaluating the height or strength of evaporation duct is the Paulus Jeske Method. This research provides analysis of annual, seasonal, monthly, daily and hourly trends of occurrence of evaporation ducts in English Channel. It is believed that such extensive insight into these ducts has not been provided before. The annual mean duct height is 7.3m. The seasonal trend shows higher values in autumn and lower in summer. Further analysis shows that occurrence of maxima is possible at any time of the year. Also, there are indications of enhancements in received signal levels due to the occurrence of evaporation ducts, despite the fact that dominant propagation phenomenon was diffraction. The findings of this study improve the understanding of over-sea propagation.","PeriodicalId":143796,"journal":{"name":"2016 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127758911","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}
