Magnetization enumerator for LDPC codes - a statistical physics approach

Jort van Mourik, David Saad, Yoshiyuki Kabashima

Research output: Chapter in Book/Published conference outputChapter


We propose a method based on the magnetization enumerator to determine the critical noise level for Gallager type low density parity check error correcting codes (LDPC). Our method provides an appealingly simple interpretation to the relation between different decoding schemes, and provides more optimistic critical noise levels than those reported in the information theory literature.
