Individual identification method for communication radiation sources based on channel equalization

Abstract

The invention discloses an individual identification method for communication radiation sources based on channel equalization, belonging to the field of communication technology. The method includes the following steps: preprocessing received radiation source signals using a blind equalization algorithm to eliminate channel distortion and obtain preprocessed signals; extracting tap coefficients of the blind equalizer after convergence from the preprocessed signals as radiation source fingerprint features; performing individual identification of communication radiation sources using a long short- term memory network model based on the radiation source fingerprint features.
