Can we control the number of channels and its constellation?

Hey,

I am working for the ofdm code. I saw ofdm.py. It implements the OFDM
modulation and demodulation, but it seems not mention the number of
channels.
How many channels are we used for the odfm ? Is it a fixed value?
Can I control the number of channels and put different constellation
scheme for each channel arbitrary ?

Look at gnuradio-examples/src/python/ofdm/benchmark_ofdm[_tx/rx].py

fft_length and occupied_tones are what you are looking for.

No. You’ll have to implement that yourself.
