Hi,For past one week I have been trying to run tunnel.py in ofdm folder. I have
successfully run tunnel.py in digital folder as well as benchmark_ofdm_*.py
with 0 packet loss.I have tried different set of parameter settings but to no
avail. If any body has successfully ran the tunnel.py in ofdm
, thus the
receiver was able to pick up some thing. Lower bandwidth works fine for Chuck
so he might not have the frequency offset problem.
Let me know if anyone has a better explanation.

Hi,
I have successfully run digital folders tunnel.py.
