Hi Alex,
I have read the generic_mod_demod.py and find the fll block you mentioned is in freq_recov block, which is before the time_recov block. However, the file sink I use to collect data is after time_recov block. So I think in this case, it's already been through carrier frequency correction. But as shown in the picture I attached with the original email, the channel I get still seems to be with carrier frequency. Please correct me if there is a misunderstanding in my thought! Thanks! Look forward to your reply!!

The corresponding C++ block is digital_fll_band_edge_cc. and you can find the usage example in generic_mod_demod.py in /gnuradio/gr-digtial/python.
There are some discussions within this community before, just search it for how to use it properly. On Wed, May 29, 2013 at 10:07 PM, yeran <address@hidden> wrote:
