Kennedy, I.O., Scanlon, P., Mullany, F.J., Buddhikot, M.M., Nolan, K.E., Rondeau, T.W. ‘Radio transmitter fingerprinting: A steady state frequency domain approach’ in Proceedings of IEEE Vehicular Technology Conference, Calgary, BC, 21-24 Sept., 4657123, 2008, pp 1 - 5
We present a novel technique for radio transmitter identification
based on frequency domain characteristics. Our
technique detects the unique features imbued in a signal
as it passes through a transmit chain. We are the first
to propose the use of discriminatory classifiers based on
steady state spectral features. In laboratory experiments,
we achieve 97% accuracy at 30dB SNR and 66% accuracy
at 0dB SNR based on eight identical Universal Software Radio
Peripherals (USRP) transmitters. Our technique can be
implemented using today’s low cost high-volume receivers
and requires no manual performance tuning.
