Abstract :
An algorithm of interference suppression for the Very High Frequency (VHF) air-ground communication in civil aviation is presented in this paper. Based on the analysis of the civil aviation VHF air-ground communication characteristics, the blind signal extraction (BSE) model for the civil aviation VHF air-ground communication is established, and the interference suppression scheme is proposed. The blind signal extraction is introduced, then an extraction method based on the kurtosis and the adaptive deflation is adopted to realize the suppression of the interference. Simulation results are also presented to show the validity of the proposed method.
