摘要
PROBLEM TO BE SOLVED: To provide a radio station identification device capable of identifying a radio station at high speed and with high accuracy by precisely narrowing down teacher data.;SOLUTION: When identifying a radio station transmitting a received radio signal, a reception frequency of the radio signal from a radio station of an identification object detected by a receiver 3 and a narrow-down parameter generated from a feature vector waveform relating to the radio signal by a narrow-down parameter calculation part 6 are used for an index. Therefore, in a radio station identification processing part 8, teacher data subjected to collation are narrowed down and extracted from a database part 9 registering beforehand feature vector waveforms relating to radio signals of radio stations as teacher data. The teacher data are successively collated with the feature vector waveform of the radio signal received from the radio station of the identification object, and the radio station of the identification object is identified on the basis of a result of calculating waveform similarity to the extracted teacher data.;COPYRIGHT: (C)2015,JPO&INPIT
