| Abstract(in English) | This paper proposes a method for location estimation of a cellular phone with illegal use using multiple sensors in an indoor environment with experimental validation. The proposal method is a location fingerprint scheme is which the statistical characteristics of the signal cross correlation among multiple sensors is employed. As the cross correlation between a pair of antenna fully stores the information of their complex channel responses, the proposed method can be considered as generalized scheme of all conventional location fingerprint ones including Received Signal Strength Indicator (RSSI), Time Difference of Arrival (TDOA), and Direction of Arrival (DOA). Besides, different from the conventional methods, in which the locality of spatial correlation is utilized, thus require fine-grid location measurements. The proposal one invokes statistical learning technique and estimates location based on the correlation of received samples with the statistical learning database. Therefore, the proposal methods superior than conventional ones in terms of location estimation accuracy and installation simplicity. An experiment conducted in this paper validates its superiority of the proposal method. |
