The behavior of iteratively decoded low-density parity-check (LDPC) codes over the binary erasure channel in the so-called "waterfall region" is investigated and shows that the performance curves in this region follow a very basic scaling law. This scaling law, combined with previously known expressions for the error floor, yields a promising direction for analyzing the performance of irregular LDPC codes of practical lengths.
