What's viterbi?
 

On a meter, you can measure BER before and after viterbi. What does
this mean?

It's error correction.

Measurements of the BER before error correction are just as useful as
knowing the BER after correction.

Normally you should worry about the pre-correction figure more than the
post-correctiuon figure.

Just out of interest, what kind of pre-viterbi measurement do you consider
acceptable. Or rather, at what point do you suck in air through your teeth
and try to work out how you can improve it.
