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
