Power Amplifier Fingerprinting of Wide Band Signals Based on Subspace Distance
Tien Tzu Hsueh Pao/Acta Electronica Sinica(2009)
Abstract
A Power Amplifier (PA) fingerprinting method based on the Volterra series model is proposed for specific emitter identification of wide band emitters. To cover the adaptability and dimension explosion shortcoming of the traditional Volterra identification method, a new MMO model is derived for the code modulation signal and the linear/nonlinear frequency modulation signal. And the distance of the subspace is adopted to compare different Volterra systems. The independent and measurable properties of the method are given, and the principle of the method is verified by the simulation experiments.
