| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Techniques for identifying wireless devices such as radar and communicator using the characteristics of the received signals radiated from wireless devices are called “Radio Identification”, “SEI ;Specific Emitter Identification”, “Radio finger printing”, and the like. These techniques are expected to be applied to detection of spoofing of wireless communication, and so on. It is known that the characteristics of the signal from radio equipment remarkably appear at the moment of rising and falling of the signal called transient response. Therefore, it is common method to use the variance, skewness and kurtosis of the instantaneous amplitude, instantaneous phase and instantaneous frequency of the rising and falling time waveform of the signal as feature quantity. However, this method has a problem that the identification performance of the wireless device deteriorates in an environment where the signal-to-noise ratio (SNR) is low. So, we propose a method for discriminating wireless devices by short-time Fourier transformation of rising waveforms, by searching parameter based on Mahalanobis distance evaluation function and by a two stage identification of model and individual. We evaluated the proposed method using actual data. The result shows that discrimination rate improved by 56 points in the low SNR environment (=10dB) as compared with the conventional method. | |
