1. JP2021180388 - TRANSMISSION DEVICE COLLATION DEVICE, TRANSMISSION DEVICE COLLATION METHOD, AND PROGRAM

PROBLEM TO BE SOLVED: To provide a transmission device collation device capable of reducing a decrease in collation accuracy even for a signal having a wide band as compared with a signal wirelessly transmitted from a transmission device to be collated when collation of the transmission device is performed.

SOLUTION: A transmission device collation device 1 includes a reception unit 1a that receives a signal wirelessly transmitted from a transmission device, a signal area detection unit 1b, a feature amount extraction unit 1c, and a collation unit 1d. The signal area detection unit 1b generates a spectrogram from the received signal received by the reception unit 1a, and detects a signal area parameter indicating a specific signal area on the basis of the spectrogram. The feature amount extraction unit 1c converts the received signal on the basis of a signal conversion parameter corresponding to the signal area parameter, and extracts the feature amount from the converted signal. The collation unit 1d calculates the similarity on the basis of the extracted feature amount and the feature amount stored in advance, and collates the transmission device on the basis of the similarity. The transmission device collation device 1 adjusts the signal area parameter on the basis of the collation accuracy in the collation unit 1d.
