Abstract (in Japanese) (See Japanese page) 
(in English) Wireless devices have trivial individual differences due to hardware imperfections. Therefore, extracting unique features from the physical waveforms of wireless signals enables us to identify transmitter devices. It has been often assumed that radio sensors can receive high signal-to-noise ratio (SNR) waveforms in previous studies. On the other hand, there have been rare evaluation examples considering lower SNR environments. Classification accuracy could decrease in case the feature is extracted from signals with low SNR. In this paper, logarithmic power spectral density (PSD) is proposed as a radio feature to improve classification accuracy in lower SNR environment. The results obtained from simulations reveal that the proposed feature enables 12-dB higher to achieve 90% accuracy than the conventional feature. Furthermore, to decrease computational complexity, dimensional reduction of radio features based on principal component analysis is applied. Simulation result shows that dimension number of radio feature can reduce to approximately 1/50 with maintenance of accuracy.
