Thanks for posting the complete reference. I must have remembered the
magazine wrong. Anyway, this article was really helpful to learn how a
Viterbi decoder is applied to an equalization problem. I took what I
learned from it and applied it to a Bluetooth system. Sklar has a
knack for clear explanation, like Rick Lyons of Understanding DSP (and
comp.dsp).

B. Sklar published a nice tutorial on that topic a while back in IEEE
Communications Magazine called "How I Learned to Love the Trellis".

Would some one be able to suggest a good tutorial or explanation of a
general implementation for a 4 or 8 state MLSE equalizer for GSM ? I
understand the theory, but would like an explanation of how, for a
specific case/example, locations on a constellation are assigned to states
and the best way to compute metrics. Preferably, something with
illustrations/trellis diagrams would be nice. Thank you.
