Abstract
Radio frequency (RF) fingerprint identification of wireless communication equipment has developed rapidly. It is to extract the equipment's RF fingerprint from the equipment's communication signals, so as to realize the identification and authentication of the equipment. In this paper, we propose a novel method for identifying pseudo-Global Positioning System (GPS) signal based on RF fingerprint. In our proposed method, we apply the Doppler frequency shift as RF fingerprint, the pseudo GPS signal and the real GPS signal is identified by extracting the Doppler frequency shift from the signal. And the experimental results show that the Doppler frequency shift can be used as RF fingerprint to identify the pseudo GPS signal well.
