  • An algorithm based on higher-order cyclic cumulants for the automatic classification of SQAM signals is proposed. The algorithm utilizes the cyclostationary property of communication signals and presents classification feature in cyclic cumulants domain. It is robust to the presence of carrier frequency offsets, time delay and phase offsets. Interesting signals can also be classified under the presence of interference signals and carrier frequency offsets. The efficiency of the proposed classification algorithm is verified via theoretical analysis and extensive simulations.
