A novel recognition scheme based on the spectrum feature analysis is proposed. A set of robust feature parameters are extracted from signal power spectrum and the power spectrum of the second and fourth power of signal. The proposed scheme can recognize many common used modulated signals in the satellite channel without any prior knowledge. Simulation results show that the scheme can achieve more than 98% recognition accuracy when SNR is above 5dB. This method is feasible and practical.
