Multipath channel estimation algorithm for automatic modulation classification using sixth-order cumulants
Vladimir D. Orlic, M.L. Dukić · Electronics Letters · 2010
An algorithm is described for estimation of multipath fading channels without a priori information on channel characteristics, for application in automatic modulation classification based on normalised sixth-order cumulants. Compared with existing approaches, the proposed algorithm can achieve much better classification accuracy in distinguishing complex-valued modulation techniques. Theoretical analysis is verified via extensive Monte-Carlo simulations.
