Automatic classification modulation based on sixth order cumulants of various structures

In this paper process of AMC based on sixth order cumulants with one conjugation is analyzed. Different channel conditions with white noise only and multipath propagation with pre-defined impulse response are considered separately. The results of classification performance are compared with results of AMC alghoritm with sixth order cumulants with three conjugations. Based on achieved results, new hybrid alghoritm has been proposed in order to improve classification results. Superior perfomance of this new algorithm is confirmed through Monte Carlo simulations.
