Hi all,
For synchronization I did not add blocks because the QAM.py calls
synchronization blocks from generic_mod file which already contains AGC,
fll, polyphase clock synk, ... I thought that those bolcks are doing the
job. So i just think to add FEC block because it is not a part of my
flow-graph. Do you thinks that i should add synchronization block even it
exists in QAM demod block? or just try to find the best parameters of
timing, frequency, and phase in de QAM_demo block?
Thanks a lot for help.
