viterbi decoder

Hi all

I'm trying to test the Viterbi decoder, but for some reason I can't get it to work.

I'm using parallel implementation with continuous optimization

traceback= 105

soft bits = 1

N = 2

L = 7

GA = 91

GB = 121

when I input a random stream or even a square wave I get a random output.

if I input a constant I get the constant back.

I've built my encoder the same way as ilustrated in the user guide (with adaptation of course to my GA and GB)

does anyone has any ideas on what can go wrong?

thanks in advance
