Hi,
I'm working on put differents modulations in differents carriers. i've
implemented my project, modifying Ofdm.py and the sorces
gr_ofdm_mapper_bcv.cc and gr_ofdm_frame_sink.cc. Now i've a doubt. The
benchamrk simulation go correctly. how can i see if the program did
the right demodulation (it did it taking informations from vector
rotated const that i puts with different modulation)??
Thank a lot
Matteo
We have provided a gr_plot_ofdm.py tool to visualize the results
(you'll find it in the gnuradio-examples/python/ofdm directory). With
the different modulations per subcarrier, the display is going to look a
bit odd, but it should show you that at least something is going on. You
could modify this code to distinguish the constellation per subcarrier
somehow.
