The UWB-IR receiver utilises a non-coherent, energy detection-based approach, which makes it largely independent of the shape of the transmit waveform and robust to multipath channels. The UWB-IR transmitter utilises a delay locked loop (DLL) frequency synthesis approach and UWB monocycle pulse generator. The UWB-IR ASIC is manufactured in 0.35 /spl mu/m SiGe BiCMOS technology. The simulated power consumption of UWB-IR transceiver circuits is 136 mW with 100% duty cycle with a 3.3 V power supply.","PeriodicalId":105819,"journal":{"name":"2005 IEEE International Conference on Ultra-Wideband","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126879019","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}

An optimal data-aided timing acquisition algorithm based on minimum probability of error criterion is proposed. The estimation of timing offset parameter is derived in closed form. The cross-modulation interference (CMI) due to multipath components during the transmission of pulse position modulated (PPM) signal is introduced. A suboptimal data-aided timing acquisition algorithm is derived from the optimal algorithm for practical implementations. The BER performances of the proposed and conventional algorithms are simulated. The results show that optimal algorithm performs better than suboptimal algorithm in CMl channel whereas the suboptimal algorithm performs as good as the optimal algorithm in CM4 channel.

Various channel correlation measurement results are shown, and system performance is tested with measured channels under different practical situations. The receiver algorithm is shown to be robust under the common situation where the receiver delays (correlation lags) have a certain offset compared to the transmit delays (spacing between two pulses in a doublet).","PeriodicalId":105819,"journal":{"name":"2005 IEEE International Conference on Ultra-Wideband","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129717045","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}

Timing with dirty templates (TDT) is a recently proposed algorithm with attractive features such as low-complexity operation, and fast acquisition in the data-aided mode. This paper is devoted to TDT performance analysis. Specifically, upper bounds on the mean square error of the blind and data-aided TDT estimators are derived. It is shown that both estimators are consistent, while data-aided TDT has an edge over its blind counterpart. To ensure good asymptotic behavior, and for the upper bounds to be valid, the shape of the transmitted monocycle should satisfy certain constraints which are specified. Analytical results are corroborated by simulations.","PeriodicalId":105819,"journal":{"name":"2005 IEEE International Conference on Ultra-Wideband","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125967705","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}

RAKE reception is important since it can make use of the rich multipath of UWB systems to improve system performance and capacity. At the same time, much research has been directed towards finding efficient modulation schemes for UWB systems. Recently, biorthogonal pulse position modulation (BPPM), which combines pulse position modulation (PPM) and biorthogonal signals has been proposed for UWB systems. In this paper we study a BPPM modulated TH-UWB system with RAKE reception over block fading channels. The capacity and error rate performance are derived over a multipath fading channel for both the single user and multiple access cases. Numerical results are given to illustrate the theoretical results.","PeriodicalId":105819,"journal":{"name":"2005 IEEE International Conference on Ultra-Wideband","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125554340","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}

An automated detection is made over the obtained confidence maps and mines detectability is analyzed on the basis of the receiver operation characteristic curves.
