Algorithm for automatic modulation classification in multipath channel based on sixth-order cumulants

In this paper one algorithm for automatic modulation classification under conditions of multipath channel, based on sixth-order cumulants, is considered. Performance of proposed algorithm is analysed within the two-ray multipath model. In comparison with fourth-order cumulants-based method, this algorithm can achieve much better classification accuracy in distinguishing BPSK from complex-valued constellations.
