In order to recognize the modulation signals when the single-channel receiver works under multi-component signal (MCS) environment, a novel approach which can directly extract the feature invariants of each independent component is proposed for the multi-component PSK signals. Firstly, the difference between the modulation methods for MCS and single signal is analyzed. Furthermore, the spectral correlation function of MCS is deduced, the method of the feature extracted is proposed. Simulation results verified that the proposed algorithm can extract the features of each independently components without disturbance, and it can effectively identify arbitrary combination of dual-signal in the given signal set.
