An Improved Design of Gallager Mapping for LDPC-coded BICM-ID System

An Improved Design of Gallager Mapping for LDPC-coded BICM-ID System

Gallager mapping uses different signal points with different probabilities by assigning several labels for one signal point, and thus provides a promising approach to achieving shaping gains. An important issue in Gallager mapping is how to assign labels for signal points. In this paper, two optimiz...
