Abstract:

A Hilbert spectrum-based approach to specific emitter identification(SEI)was proposed in single-hop and relaying scenarios. The correlation coefficient measuring the similarity between Hilbert spectrums was employed as the identification feature. An identification problem was also in-depth explored for a relaying scenario, in which the fingerprint of different emitters can be impaired by the relay's fingerprints under non-ideal conditions, such as non-Gaussian noise and flat-fading channels. Extensive simulation demonstrates that the proposed approach can achieve a good identification performance in both single-hop and relaying scenarios, and shows robust against non-ideal channel conditions as well.
