Weight Enumerators and Cardinalities for Number-Theoretic Codes.
TL;DR: In this paper, a generalization of the complete weight enumerator for the number-theoretic codes is presented, which allows us to derive the weight enumerators and cardinalities of the non-binary Tenengolts' codes.

Spatially-Coupled Binary MacKay-Neal Codes for Channels with Non-Binary Inputs and Affine Subspace Outputs
TL;DR: The decoding system considered in this paper can be viewed as a simplified model of the joint iterative decoder over non-binary modulated signal inputs e.g., 2-QAM and binary spatially-coupled MacKay-Neal codes by density evolution.
