I don't have much to add, but Nick and Sylvain touched on the largest difference between the Gnuradio GMSK demod and GSM/TDMA type burst processing - and it's not the Viterbi. The use of synchronization loops (or lack thereof) in the demod is really the separating factor. -TT _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
