Especially from the viewpoint of antenna optimization, the channel modeling approach should be able to de-embed the antenna contribution to the channel response. Two modeling approaches using spherical wave functions (SWFs) and orthogonal dipoles (ODs) have been proposed so far for this purpose, and the simplified form of the SWF channel modeling involving only fundamental modes is equivalent to OD channel modeling. Although the modeling by SWF fundamental modes or the ODs is practical, the accuracy of their channel approximation should be clarified in advance, hence the purpose of this paper. For the analysis of the accuracy, deviated dipole is utilized to model the antennas in finite size which can emit the higher modes. Applying the finite-difference time-domain method to the deviated dipole and the animated human body, the approximated and the exact channel response are obtained. The error due to the approximation is then modeled by log-normal distribution, of which statistical parameters are empirically obtained as the function of either the antenna size or residual power.","PeriodicalId":6624,"journal":{"name":"2015 9th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"61 1","pages":"25-29"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76500016","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}

In a realistic WCE scenario, it is important to precisely estimate the WCE location. Generally, the superiority of TOA-based localization over RSSI-based localization has been pointed out in many papers in wireless communication systems. However, because the propagation speed inside of a human body varies due to the influence of its biological tissues (namely, the relative permittivity of human tissues), the realization of precise TOA-based localization needs to accurately estimate the propagation velocity of implant communication signals. So, in this paper, we propose a TOA-based method for joint location/relative permittivity estimation, and then compare the performances between TOA- and RSSI-based WCE location estimation methods. Our computer simulation results reveal that, the TOA-based localization with accurate relative permittivity information outperforms the RSSI-based localization in terms of the localization accuracy, whereas the RSSI-based localization is advantageous if accurate relative permittivity is not obtained. Additionally, the proposed TOA-based localization can achieve not only better localization accuracy than that of the RSSI-based localization but also accurate averaged relative permittivity estimation.","PeriodicalId":6624,"journal":{"name":"2015 9th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"12 1","pages":"139-143"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77724192","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}
