Summary: Definition of trellis coding

Basically, trellis coding is a method of coding without bandwidth
expansion so that you don't lose, by admitting more noise, while you're
trying to gain by correcting errors.

A pair of good tutorial articles by Ungerbock can be found in the
February, 1987, issue of IEEE Communciations magazine.  He is the
"father" of trellis coding.
