I’m trying to figure out what the test_corr_and_sync example (located
showing me. I see the tags added by the correlator, but they seem to
around a bit. If I add some timing offset with the slider, I don’t see
relation to that and the time_est tag value. I can’t find any
between the four sliders and any of the tag values.
I also see the constellation being smeared out considerably. It looks to
like the rrc_taps variable might be set incorrectly. The number of taps
portion of the filter does not match the constellation modulator number
taps (5sps vs 11sps). Though changing this to what I believe is
does not help the smear all that much. Shrug.
If this is working as intended, what net effect does this have on the
pfb_sync and costas filters? Is it a considerable boost in sync
