The average weight distribution of tanner code ensembles and a way to modify them to improve their weight distribution
Jean–Pierre Tillich · 2004
This paper computes the asymptotic average weight distribution of Tanner code ensembles. The result obtained generalizes formulas, which were known for LDPC code ensembles. Also derive sufficient conditions ensuring that such a family contains a subfamily, which is asymptotically good and a ways to modify them to improve their weight distribution.
