For updating the blks2_dxpsk2_demod.xml to match the usrp_rx_dpsk.py
__init__(self, samples_per_symbol=2, excess_bw=0.35, freq_alpha=0.01,
phase_alpha=0.01,timing_alpha=0.1, timing_max_dev=1.5, gray_code=True,
verbose=False, log=False,sync_out=False)
I'd like to add freq_alpha and phase_alpha column to the GRC block,
could anyone advice on the callback sections, where's the clock_recov and
time_recov.set_alpha go for?
thanks!
- <callback>clock_recov.set_alpha($costas_alpha)</callback>
- <callback>clock_recov.set_beta(0.25*$costas_alpha**2)</callback>
<callback>time_recov.set_alpha($timing_alpha)</callback>
