Fwd: [Discuss-gnuradio] Ofdm parameters

[Jacopo]

Thanks! But where can i check this parameter?

Is it possible that fft_length= occupated carrier (--occupied-tones in blksimpl/ofdm.py) + un_used carrier ? Where can i set the position of the occupated_bins?

bye

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