Pktno of OFDM transmission

Hi All,

I am working on digital communication using OFDM. And I tried to run the
file in /gnuradio-3.1.2/gnuradio-example/python/ofdm

@ TX side:
sudo ./benchmark_ofdm_tx.py -f 420M --tx-amplitude 6000

@ RX side:
sudo ./benchmark_ofdm_rx.py -f 420M

At the TX side, the pktno = 2500, however, at the RX side, the pktno =
2499. Can anyone tell me why is that? and how to modify it?

Thanks,
Brook
