Title
(EN) TRANSMISSION APPARATUS RECOGNITION APPARATUS, TRANSMISSION APPARATUS RECOGNITION METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM
Abstract
(EN)

A transmission apparatus recognition apparatus includes a receiver configured to receives a signal wirelessly transmitted from a transmission apparatus, a signal region detector, a feature extractor, and a recognizer. The signal region detector generates a spectrogram from a received signal received by the receiver, and detects a signal region parameter indicating a specific signal region based on the spectrogram. The feature extractor converts the received signal based on a signal conversion parameter according to the signal region parameter, and extracts a feature from the converted signal. The recognizer calculates a degree of similarity based on the extracted feature and a feature stored in advance, and recognizes the transmission apparatus based on the degree of similarity. The transmission apparatus recognition apparatus adjusts the signal region parameter based on a recognition accuracy of the recognizer.
