Yep, looking at .h helped but raised a question. In the
gr_simple_correlator.h
inline int slice (float x)
{
return x >= d_avg ? 1 : 0;
}
which makes more sense to compare to the average, but in .cc you also have
inline static int slice (float x)
{
return x >= 0 ? 1 : 0;
}
Which one is used in the call
decision = slice (in[n]);
in the general_work?
Thanks on the explanation of the bit counter. From the call to it, I get
that it counts how many bits in the stream match the GRSF_SYNC code.
I still don't get how the oversampled data gets used. I would think that
d_shift_reg would get the average value of the input over the oversampled
period. I don't see how the code does that.
PS: See my reply to
http://lists.gnu.org/archive/html/discuss-gnuradio/2005-11/msg00204.html
(subject gmsk error)
for why I am still looking at using this type of sync.
