Abstract: PUE attack users illegally occupy the primary user’s channel,resulting to the decrease of cognitive user’s available spectrum resources.Based on the fingerprint characteristics of the radiation source,this paper defined the fractal dimension weighted,and depicted the intrapulse fluctuation characteristics of the communication signal envelope.We proposed a new method of PUE attack detection by the feature extraction of radiation source.Theoretical analysis and experimental results show that this method can effectively distinguish between the main users and PUE attacks users,and it will play a great role in the field of information security.

Key words: PUE attack users,Radiation source feature extraction,Fractal dimension
