Abstract: The present invention relates to a practical design of an algorithm in which modulation schemes are automatically classified for a target signal in the state that the information of the target signal cannot be known. In general, most conventional automatic classification algorithms may be not applied to signals under actual environment states such as hostile communication and restrict a target signal because the algorithms are suggested under the assumption that information of the signal is previously known to some extent. In addition, the automatic modulation scheme classifying algorithm may be not designed without recovering a propagation frequency. The present invent suggests a scheme of determining a modulation index (M) of the target signal without complex computations by using the characteristic of an auto correlation function after classifying the signal into a PSK (single carrier) class signal and an FSK (variant carrier) class signal by utilizing a phase difference of an input signal in order to effectively acquire the information of the target signal.
