Ofdm parameters

Hello I’m studing an OFDM implementation on gnuradio. I want to modify
benchmark_ofdm_tx.py.

I have just read ofdm.py and trasmit_path.py but I can’t find how change
some parameters.

I’d want a bandwith of 20Mhz, where I can set this option? Where can I
set
the carriers number? And the pilot bins?

Is it possible to set an adaptive modulation for differents carriers?

Thanks a lot!

The USRP hardware is not capable of bandwidths that high. You are best
off staying around 6 MHz.
