Hi Vanessa, One thing you might also have to change is the tx-amplitude in transmit_path.py. I wasn't having any success until I changed the range from 0 <= AMPL < 32768 to 0 <= AMPL <= 1. I'm interested in whether you have any success with this. I'm currently able to send something that looks like OFDM, but unable to demodulate it.
