It is well known that linear dependence relationship between the observable and unobservable state variables can be found by traditional determinant method. But there is no single method which could resolve the usual difficulties in observability completely. An improved determinant method is introduced to solve this problem in this paper. It is shown here that observable state variables can be determined by establishing an information matrix based on the linear dependence relationship between observable and unobservable state variables. Also, the best choice of unobservable state variables could be performed easily by fast evaluation of observability degree based on the established information matrix and the initial error covariance of state variables. A step by step procedure is presented. Simulation results confirm the effectiveness and advantage of the new improved approach, which is applied to application of initial alignment of SINS.","PeriodicalId":196304,"journal":{"name":"Proceedings 2013 International Conference on Mechatronic Sciences, Electric Engineering and Computer (MEC)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121668934","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}

Anti-spoofing in acquisition can firstly find spoofing signal. In this paper, a new method is proposed to alarm receiver whether there is a spoofing signal: in acquisition stage, if receiver finds two correlation peaks above a threshold for two times continuously, it indicates a spoofing signal; while if one peak, only if the rough signal-to-noise ratio is lower than a power threshold and the width of correlation function is lower than a width threshold, it has no spoofing signal. The theoretical calculation methods of thresholds above are all presented there. Also, the influence factors and performance analysis is presented. Results show that we give a quantitative power threshold; and by introducing the width of correlation function, it can deal with the condition that the authentic and spoofing signals are overlap, while methods existed can't. Our work is significant for designing anti-spoofing receiver.","PeriodicalId":196304,"journal":{"name":"Proceedings 2013 International Conference on Mechatronic Sciences, Electric Engineering and Computer (MEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131213431","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}

During the process of identity recognition, the PPIs were collected with platform system in normal walking speed. The sparse representation of PPI was then obtained according to the sparse basis (i.e., wavelet basis). Finally, measurement vectors were calculated by the Topelitz measurement matrix and the PPI was recognized by compressed sensing classifier. The results showed that the accuracy of identity recognition of PPI based on compressed sensing exceeded 97.76%, demonstrating the effectiveness and stability of the Topelitz-compressed sensing algorithm. Meanwhile, the method used in this study reduced the data storage amount and increased the real-time recognition during the PPI process.","PeriodicalId":196304,"journal":{"name":"Proceedings 2013 International Conference on Mechatronic Sciences, Electric Engineering and Computer (MEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131433867","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 majority voting rule improves the watermarking robustness and reduces the probability of false positives.
