Costas_loop_cc ()

GNU Radio

Hi,

I found that for CFO compensation, there is the module named
“costas_loop_cc
()”
Use it in this way: gr.costas_loop_cc(alpha, beta, max_freq, min_freq,
order)

where I can find this C++ file? I search the files, only found one
“gr_costas_loop_cc.cc” in ~/gnuradio-3.2.2/gnuradio-core/src/lib/general
But It seems like this C++ function is not the one they use. As I tried
to
print out some variable, but no observations.

Sorry to disturb you guys! :frowning:

Of course its the same file. If you are making any changes in the C++
file
then you must compile it before you can see those changes. Did you do
“make”
and “make install” after your changes?
