The transmission of sensor measurements relies on its digitized data being organized as a set of bits. This sequence or frame contains preamble information (the preamble is used to signal that \"here is a train of data coming\" to the receiver), a data sequence, and finally \"end of signal\" bits. In order to achieve frame synchronization in packet-based communication systems, a known sequence (pre-amble) is sent at the beginning of each packet. This paper presents a low power scheme for preamble detection using dynamic precision configuration. The proposed scheme is based on the observation that signal processing algorithms at the front end (including mixer, square root raised cosine (SRRC) matched filter and code matched filter (CMF)) of the receiver, can be operated with minimum precision during the acquisition phase without incurring significant acquisition performance degradation. The SRRC filter is designed to achieve minimize inter-symbol interference, while the CMF is designed to improve the signal to noise ratio. The result is an acquisition system design that consumes less than 25% of power dissipation that is consumed by other typical implementations.","PeriodicalId":274130,"journal":{"name":"2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116742690","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}

On the first place, however, this technology gives the designer the possibility to increase efficiency of designed system by exploitation of parallelisms of implemented algorithms. Moreover, it is possible to apply special techniques, such as distributed arithmetic (DA). Since in this approach general purpose multipliers are replaced by combinational LUT blocks, it is possible to construct digital filters of very high performance. However LUT blocks can be of considerable size thus advanced synthesis methods have to be used to map them efficiently into FPGA resources. In this paper an application of the functional decomposition based synthesis in implementation of digital filters for wavelet transform has been investigated. The paper presents many examples confirming that decomposition allows reducing logic cell utilisation of filter implementation based on distributed arithmetic concept with no performance degradation and even increasing it.","PeriodicalId":274130,"journal":{"name":"2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117010118","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}
