Hierarchical digital modulation classification using cumulants

WebA hierarchical modulation scheme to resolve the issue of asymmetric node positioning was proposed in [9]. Also, the integration of lattice codes with PNC was discussed in [10], which, however, is difﬁcult to implement in practice [6]. In this paper, we focus on a practical solution to syn-chronous PNC with M-QAM modulation.
