Talk:Low-density parity-check code

For a person who has not studied information theory, the introduction chapter says absolutely nothing. It's some state of the art code, rrright. For what/Where/Why is it used? I think the introduction should answer these questions first. Then it's okay to jump into the technics. Besides, what's Forney's factor graph notation anyway? Maybe an article about it should be created, or at least Forney linked somewhere. (Elsewhere than to Forney, Texas). --ZeroOne 19:52, 12 Oct 2004 (UTC)
