The technique uses a preamble and is thus especially suitable for burst mode communication. The preamble consists of orthogonal training sequences simultaneously transmitted from the various transmit antennas. The proposed system exploits all subcarriers in frequency domain, which provides a remarkable performance improvement, and reach the Cramer-Rao Lower Bound (CRLB). A new algebraic estimation method is proposed, in order to exploit the powerful algebraic ASTC technique in wide-band systems, when the CFOs occur with small variation and to overcome the sensitivity of the ASTC codes in frequency synchronization problemof OFDM system.","PeriodicalId":176786,"journal":{"name":"2011 11th Mediterranean Microwave Symposium (MMS)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128361810","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 dimensions of the fractal antenna are optimized to ensure a proper conjugate impedance matching with the chip input impedance over the UHF RFID band (860–960 MHz). The performance of the designed antenna has been simulated using the electromagnetic simulator, ADS Momentum, based on the method of moments (MoM). The input impedance, conjugate match factor and the read range are illustrated.","PeriodicalId":176786,"journal":{"name":"2011 11th Mediterranean Microwave Symposium (MMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129226344","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}

Interdigital hairpin structure is applied in the dual band-notched UWB bandpass filter design. By adding only one pair of folded fingers on both side extremities of single band notched UWB bandpass filter, the fabricated filter can suppress the second and third harmonics of fundamental frequency. The dual notched bands can be easily controlled by changing the parameters of each finger. Without changing the first notched frequency band, the second reject frequency band can be shifted by changing its corresponding parameter of finger independently. In this paper, one dual band-notched UWB bandpass filter are designed to control the second and third harmonics of 2.14 GHz. The measured result of the final fabricated circuit shows that insertion loss at 4.28 GHz and 6.42 GHz are 13.99 dB and 4.16 dB, respectively. Because of the folded finger structure, the filter is compact in size. The dimension of our proposed filter is 5.5 mm × 21.3 mm.","PeriodicalId":176786,"journal":{"name":"2011 11th Mediterranean Microwave Symposium (MMS)","volume":"8 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113976672","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}
