Analytic Determination of Scaling Parameters

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.
