Abstract :
An independent component analysis (ICA) and higher order cumulants based modulation classification algorithm, which is applicable for the presence of interference signals, is proposed. As the modulation type of interesting signal is different from that of interference signals, the proposed classification algorithm has better performance in large SNR range. The efficiency of the proposed classification algorithm is verified via extensive simulations.
