Analytic Determination of Scaling Parameters
Abdelaziz Amraoui, Andrea Montanari, Rudiger L. Urbanke · 2006
We show that the finite-length scaling parameters for irregular LDPC codes when used over the binary erasure channel can be computed without resorting to "covariance evolution". We provide simple expressions that can be evaluated using solely the degree distributions and the characteristics of the fixed point of density evolution
