Most of the proposed indoor positioning and tracking algorithms try to identify and mitigate the errors caused by the non-line-of-sight propagation paths. In this paper, we propose a three-dimensional tracking technique to track a mobile terminal which moves in a non-line-of-sight multipath environment by applying the extended Kalman filter. The proposed tracking technique requires at least one base station and exploits the non-line-of-sight propagations to estimate the three-dimensional trajectory of a mobile terminal by considering the successive angle-of-departure, angle-of-arrival, and time-of-arrival measurements under the assumption of stationary scatterers. Additionally, the position of the scatterers is determined implicitly. It is shown, by simulations, that the proposed three-dimensional tracking technique can estimate the trajectory of a mobile terminal in non-line-of-sight multipath environments very well. In general, the proposed tracking technique improves the position estimates of the mobile terminal compared with tracking made by successive independent position estimates. The improvement in position estimates comes from the exploitation of the correlation between successive measurements which arise from the physical mobility constraints of the mobile terminal.","PeriodicalId":399340,"journal":{"name":"2012 9th Workshop on Positioning, Navigation and Communication","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129955461","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}

Our engine simulates a scenario which consists of given anchor positions and evaluates all positions of a playing field in parallel, instead of only randomly selected positions. At the end of a simulation run, the user is able to judge the strengths and weaknesses of the algorithm in a picture that displays the spatial position error distribution, a representation of positions in a plane with their errors. Understanding spacial distribution of error is especially valuable, because we observed that it depends on the placement of anchor nodes. This enables the developer to optimize his algorithm or aid him in selecting an algorithm for his application. The simulator's design separates the simulation engine, the lateration algorithms, and the error models. The simulator can be easily extended with additional lateration algorithms and error models. The engine is written in GNU C99 and uses the SSE or AVX vector extensions of modern microprocessors. Thus, it is able to scale fully to all cores. Beside extendability, the main focus is set on execution speed.","PeriodicalId":399340,"journal":{"name":"2012 9th Workshop on Positioning, Navigation and Communication","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130024560","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 array sensor uses only one array antenna as the receiver to observe the signal subspace spanned by eigenvector through array signal processing. The signal subspace represents the radio wave propagation of interest. Based on the eigenvector, it can detect and classify simple human activities: entering a room, standing, and moving. The advantages of the system are as follows: it guarantees privacy of users; it eliminates installation difficulties; it also offers a wide detection range. Although the conventional method can detect simple human activities, it cannot determine the position of the human being in detail. The proposed method uses multiple transmitters emitting different frequency signals to extend the dimension of the signal subspace. In addition, we separate coherent signals by using the SSP to obtain more features of radio wave propagation than the number of transmitters. The features are used as inputs to SVM to localize human position. The experimental results show that the proposed method improves the localization accuracy and the root mean square error (RMSE) compared to the previous method.","PeriodicalId":399340,"journal":{"name":"2012 9th Workshop on Positioning, Navigation and Communication","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116023626","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}
