| Abstract: | A recognition algorithm of digital modulation signals based on high order cumulants(HOC) and constellation was presented,which connected high order cumulants with improved constellation clustering and adopts hierarchical multiclass classifier to identify digital signal types.The feature parameters were invariant with the respect to difference of amplitude and phase,and they could suppress additive Gaussian noise effectively.Simulations showed that the success rate was over 93% for recognition of the differe... |
