Hello all,
When using pll_carriertracking_cc, the returned spectrum seems to be inverted about 0MHz, when looking though the code line 113 of gr-analog/lib/pll_carriertracking_cc_impl.cc looked odd:
> optr[i] = iptr[i] * gr_complex(t_real, -t_imag);
could someone explain why the the imaginary component of the NCO is inverted?
Thank you all,
Andrew
