The essential drawback of this method is reduction of maximum estimated frequency offset range with increasing the length of preamble. Recently, Zhang et al. proposed a method for joint frame synchronization and carrier frequency offset estimation scheme in OFDM systems. To the best knowledge of the authors, no extend of this method for MIMO-OFDM systems have been presented in the literature yet. In this paper we propose a new extension of joint frame and frequency synchronization of MIMO-OFDM systems with the preamble we name it \"Mirror preamble\". Increase the maximum carrier frequency offset acquisition range up to one half of the total bandwidth of all subcarriers is a desire result obtained from mirror preamble. In this paper we have used Zero Correlation Zone (ZCZ) sequences in the proposed preamble structure and to the contrary of Zhang et al. that neglected the effects of dispersive multi-path channel in their analysis, we have a discussion about reduction of these effects in the methods based mirror preamble.","PeriodicalId":413993,"journal":{"name":"2007 3rd IEEE/IFIP International Conference in Central Asia on Internet","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114862181","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}

As sensor node platforms typically have computation blocks that can handle a minimal set of instructions (8 bit microcontrollers and less) and are greatly constrained (8KB static firmware footprint and 64KB RAM), the clear challenge in supporting multi-applications (and hence multi-radios) to enhance the sensor 's functionalities is the implementation of different radio and application profile stacks on the embedded system. The main design bottlenecks are system architecture optimization for multi-radio stacks, application-driven PHY/MAC emulation in the 8KB static firmware and of course, ensuring low power and high battery life. Our studies indicate that overcoming these embedded systems engineering bottlenecks in sensor node designs involves rethinking a few standards and raising the need to have new standards in the IETF LoWPAN WG. On this paper, we would like to show the need to introduce a new protocol in the LoWPAN WG derived from overcoming some of the sensor node design bottlenecks in seamless pervasive indoor environments.","PeriodicalId":413993,"journal":{"name":"2007 3rd IEEE/IFIP International Conference in Central Asia on Internet","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117090428","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}
