I want to send one ofdm symbol then mute during one symbol, and loop in that
way.
I have tried to make the second symbol to be all 0+0j in baseband. But the
output remains
an output noise which is not as low as requied. I think the RF always output
something even
if the baseband gives him 0+0j.
When I use gnuradio ofdm benchmark_tx.py and benchmark_rx.py at two USRPs to
perform an ofdm transceiver,
I have observed that sometimes, the BER boosts for a short while. Almost all
the bits are wrong at that moment.
After debugging, I've found that during that period of time, the correlation
