<P>PROBLEM TO BE SOLVED: To provide a radio device identification device that can accurately identify a radio device. <P>SOLUTION: A radio device identification device receives an electric wave emitted by a radio device and determines, as a feature vector, a signal obtained by differentiating an envelope detection signal at the time of rising of the signal by a differentiation processing part, and identifies an originating device based on the degree of similarity between the feature vector and a teacher vector that is a feature vector of a known radio device that has been obtained in advance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
