Thanks Paul.

I have added a link on my blog at

There should be a "Nicholson limit" for how well something of a certain complexity can be explained using a given number of words with a high probability of being understood correctly.  Your paper is about as good as it could ever get.  Thanks Paul.

I wrote a non-mathematical introductory article about how
forward error correction works.

There's a lot of material on the web about FEC but most
of it is very technical and tends to concentrate on one or
another particular coding scheme.  I couldn't find anything
that demonstrates and really explains in simple terms the
essential principle of it.

So I thought I'd try to write something, perhaps to see if
I can understand it myself.

The article should appeal to anyone who's wondered how 'coding'
a message, which increases its bandwidth and reduces its S/N,
can actually lead to greatly improved communications.

Whether I've succeeded or not, the reader will have to judge.
