Power Ramped-up Preamble RF Fingerprints of Wireless Transmitters
MetadataZobrazit celý záznam
In this paper, we propose a novel kind of RF fingerprints (RFF) with better discriminability than typical RFF for identifying preamble-based wireless transmitters. First, the equivalent model of RFF identification system is built. Then, the typical RFF are analyzed with the built model and the novel RFF, which is transformed from preamble signal when its power is ramped up, is presented. Finally, the discriminability of the proposed RFF and typical RFF is experimentally evaluated with Wi-Fi 802.11b devices. The proposed RFF can be integrated into fusion identification of preamble-based wireless devices with multiple RFF.
