Individual identification method for communication radiation sources based on receiver distortion compensation

Abstract

The invention discloses an individual identification method for communication radiation sources based on receiver distortion compensation, including: constructing a reference receiver and a receiver to be compensated; training a compensation module according to signals of the two to learn distortion differences; performing preliminary compensation on signals of the receiver to be compensated; performing residual IQ imbalance compensation on the preliminarily compensated signals; and completing individual identification of communication radiation sources based on the compensated signals. The method effectively eliminates hardware distortion of receivers and improves the accuracy and robustness of identification in cross-receiver scenarios.
