| Abstract(in English) | A wireless capsule endoscope (WCE) is a promising medical device for diagnosis of digestive organs, which takes pictures inside digestive organs, such as large and small intestines and transmits them through implant wireless communications. Location information of the WCE is important because it is useful for doctors to diagnose diseases. Generally, the fact that TOA-based localization is superior to RSSI-based localization in terms of localization accuracy has been reported in many papers in a field of wireless communication systems. However, the propagation speed inside a human body varies depending on the human biological tissues, therefore the realization of precise TOA- based localization needs to accurately estimate the propagation velocity of implant communication signals. For this reason, we propose a TOA-based method for joint location/relative permittivity estimation in this paper. In addition, we compare the localization performances between the TOA- and RSSI-based WCE location estimation methods by computer simulations. |
