I'm voting for it as well. fred is def a cool prof. Excuse my ignorance but
am I right that fred is a co-inventor of this window?

I have the same question. What is the easiest way to modify benchmark_*.py
to make them work with UHD?

Hi,
Can anyone explain to me why do we need the hackery in OFDM tunnel? Is there
a problem with having different transmit and receive frequencies?
Thanks,
Tuan

To follow up with Chuck's question, I'm also having problem running tunnel
using OFDM. The individual transmissions between the 2 USRPs were fine
(albeit that I had to manually adjust the center frequency of 1 USRP (A) to
cope with the frequency offset). I had B operating at 2412MHz and A at
2411.9
Hi,
I have installed the GNU Radio Debian binary library (3.2.2) on my laptop
running Ubuntu 10.04. Is there an easy way for me to make minor changes to
the C++ source codes and add it to the binary library?
Thank you,
Tuan

Sorry for bringing up an old thread. I was having the same problem of not
receiving packets using benchmark_ofdm_* and changing the receiver frequency
to tune to the transmitter frequency indeed solved the problem.
However, if I have to manually do it every time, I don't see how I can get
ofdm tun
Unfortunately tunnel.py in the ofdm folder doesn't work for me either. Since
you had benchmark_ofdm_* running, I would use the same settings for tunnel.
I don't even have benchmark_ofdm_* going at any setting. I'm trying to get a
hold of a spectrum analyzer. Hopefully it would help to clear things
I finally found a setting that actually works. So the real problem I think
lies in the bit rate. I had no communication whatsoever in low bit rate
(~250k). I started to have unreliable comm. at 500k and at 1Mbps I got no
packet drops for tunnel.py. However, even at 1Mbps I still got about 5%
drops
That's pretty much the same settings that I have. Can you clarify a bit
more:
- How far apart are your boards?
- What options did you use to run tunnel, benchmark_ofdm_*, benchmark_*.
- When you run benchmark_*, did you get a lot of packet drops at the end of
transmission (about 15%)?
Thanks a
Chuck,
What hardware are you using?

Juan,
Thanks a lot for your response. I tried stopping at the ifconfig stage and
wait for both PCs to be ready before hitting enter. But all I saw was TX and
no RX. Do you have any idea where the problem might be?

Did you manage to have an IP/TCP section working? I tried changing both the
carrier threshold and interpolation, decimation values but every time I
tried pinging the other USRP, I got the message 'Destination Host
Unreachable'.
I tried benchmark_tx/rx and always had packet drops; benchmark_ofdm_tx
Sorry I forgot to edit the title in the last post.

Hello all,
I am working in the same team with Shalabh. We have been trying to figure
out this problem for a week now and so far we found nothing concrete. We
have been looking in every corner of the archive. We found some people who
had similar problem with us (some dated back to 2008!) but no one
That's precisely where it is. Don't know how I missed it. Thanks a lot.

Hi all,
This question might be a little bit off-topic but going through the code on
the transmission side, I didn't see CRC method got invoked anywhere. Though
I did see that the CRC got removed and checked in the receiving side. I'd be
grateful if anyone can give me a pointer.
Thanks,
Johnny
