Re the recent change to say that code rates could be equal to 1, I don't know of any such codes ever being used in practice, and it certainly doesn't seem very useful...

There *are* codes that when combined with M-ary modulation schemes produce one output symbol per input bit, but the output symbols are non-binary. But I don't think that's what you meant. Can you clarify?? User: Karn

From BrettE: This page doesn't descripte the ENCODING at all. Perhaps I'll add some of that later...

Josh Rubin: I second BrettE. The page for Reed-Solomon codes gives a rough but accurate definition; this page manages to talk about convolutional codes without defining them. A definition of "convolution" as used in mathematics and signal processing is in order too.
