An algorithm for jamming recognition based on inspecting spectrum of satellite communication

Jamming detection and jamming recognition are the key technologies of intelligent anti-jamming in the satellite communication. To solve the problem that the jamming is difficult be recognized in the satellite communication, a new algorithm for jamming recognition based on the high order cumulants(HOC) and wavelet transform is proposed. The algorithm analyzes the familiar jamming with the high order cumulants in frequency domain and extracts feature parameters of each jamming; The classified models of each jamming has been established for recognition. In the process of recognition, we adopt the wavelet transform for denoising the received jamming. It is proved that the mentioned algorithm can recognize the familiar jamming correctly in satellite communication under low SNR.
