The code is generic enough to handle any problem that can be cast as 
sequence detection for a sequence generated by a trellis. This includes 
puncturing, sequence detection in the presence of ISI (aka, viterbi 
equalization), CPM demodulation, etc...

Can you post the data file? I remember that I had tried a correlation 
based (joint) frequency/time synchronization algorithm with your 
previous data and it didn't work...
