Abstract
A graph-theoretic method for analyzing a scheme of combining modulation and error-correcting codes (ECC), in which certain bit positions in the modulation code are left unconstrained for insertion of ECC parity bits is presented in this paper. We establish several properties of the tradeoff function that relates the density of unconstrained positions to the maximum code rate, including concavity and continuity.
