The proposed schemes are based on identifying the analog hardware impairments of the transmitter. In this regard, phase noise analysis and its measured signatures reveal that low to medium end software defined radio (SDR) acting as FBS can certainly be detected if the detecting terminal’s own phase noise is at least 10-dB better than the transmitter. However, for medium to high end FBS, a computationally efficient network synchronized carrier frequency offset (CFO) approach has been proposed and the measurement results confirm that the regular base stations (RBS) that are clock synchronized show identical CFO values whereas, the FBS show large and random offset values. Furthermore, the CFO stability (Frequency offset vs. time) signatures illustrate that an FBS running by its own lazy clock show a large instability in the frequency offset values and even in case of a precision clock, fluctuations vanish though the stabilized offset is still large enough for a user terminal to distinguish the FBS from the RBS.","PeriodicalId":328717,"journal":{"name":"2019 IEEE 20th Wireless and Microwave Technology Conference (WAMICON)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130925656","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}

Out of several WPT schemes, the nearfield magnetic link shows potentials for short distance wireless power and data transmission. However, the power-transmission efficiency of magnetic link is limited by the low coupling factor and the quality factors of the transmitter and the receiver coils. To overcome this challenge, a high-efficiency three-coil inductive power link with resonant capacitor is proposed to improve the working bandwidth. Prototype coils are designed and fabricated on FR4 substrate and HP 4396B Network Analyzer is used to measure the performance of the 3-coil link system. Simulation and measurement results indicate that the proposed system has a transfer gain 42 dB higher than that of the two-coil coupled inductive link under resonant condition.","PeriodicalId":328717,"journal":{"name":"2019 IEEE 20th Wireless and Microwave Technology Conference (WAMICON)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127296570","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}
