Achilleas,
great. I'll then focus for now on implementing time/frequency
synchronization. Does the decoder support puncturing? Did you publish
you code already?
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...
Concerning my "jitter" problem: I sampled another DAB source with the
DBSRX daughterboard and implemented a correlation based frequency
synchronization algorithm. That pretty much solved the problem (although
a little jitter is still there).
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...
Achilleas
