Bethe Free Energy Approach to LDPC Decoding on Memory Channels
Jaime A. Anguita, Michael Chertkov, Mark A. Neifeld +1
We address the problem of the joint sequence detection in partial-response (PR) channels and decoding of low-density parity-check (LDPC) codes. We model the PR channel and the LDPC…

Provably efficient instanton search algorithm for LP decoding of LDPC codes over the BSC
Shashi Kiran Chilappagari, Michael Chertkov, Bane Vasic
We consider Linear Programming (LP) decoding of a fixed Low-Density Parity-Check (LDPC) code over the Binary Symmetric Channel (BSC). The LP decoder fails when it outputs a pseudo-…
