| Abstract(in English) | As a location detection method without using GPS, there is a fingerprint method. It measures the received radio wave power transmitted from multiple base stations at each location in advance and estimates the location by pattern matching with the received radio wave power of base stations measured at each terminal. In the fingerprint method, the more position fingerprint data it has, the more computation is required. Since the receiving performance deference between a receiver to be measured in advance and a terminal is different, it is necessary to compensate for the difference in order to improve the accuracy of position estimation, which requires a huge amount of computation. In this paper, we propose "fingerprint method by using last received data on time series and correcting receiving performance deference", which restrict search range of terminals in order to drastically reduce the huge computational volume without degrading the location estimation accuracy, and clarify the position estimation accuracy of proposed method. |
