Hi all,
I am implementing a 2X2 mimo system using usrp2s. While looking through the
mail archives,
i came across a reference to a mimo system based on 'benchmark_ofdm_mimo'
from Tom Rondeau's
repository. How do i access this repository?
Thanks in advance

Hi Roberts,
Greetings. Thank you for your input.
I am able to bring up my system with Ubuntu 10.10 and with latest gnuradio
as well able to run the grc file successfully and see the output on screen.
However, would like to know how the same to integrate and generate and take
the signal from USRP

Hello Josh,
Starting again seems to have solved the problem except for:
99% tests passed, 1 tests failed out of 102
Total Test time (real) = 62.09 sec

Thank you so much for the response Michael.
I will try to figure out what's going on with both ways and I will post
updates to the list too.
Thanks,

Hi George - I believe there are 2 possible solutions, though I've never used or
tested either myself. If you just want to verify that what you want to do
works, I think (1) should be quite straight forward.
1) This method will certainly work, but it's not very robust : Make your

Hi List,
I install the gnuradio and UHD in different time, and when I run a python
script, it tells me:
RuntimeError:
GR-UHD detected ABI compatibility mismatch with UHD library.
GR-UHD was build against ABI: 3.4.0-1,
but UHD library reports ABI: 3.4.0-2

Hi,
I am trying to run an old application that was working previously but when I
upgraded to 3.6.1 I get the error in the title. Has anybody encountered and

Hi Community,
I was doing video transmission using tunnel.py. I set the bitrate 1000k and
everything was fine. But when I set it to 1500k and above I was getting
BB in the terminal where I typed ./tunnel.py -f 2.45G --bitrate
1500k
What does this BB means ?

Hi Martin,
Yes I had seen the cmake branch and was considering trying it.. I'll
try it soon and let you know. However I now suspect the problem is
with my gcc version/config messing up the -fPIC argument. What
compiler and version do you use to compile? I use GCC 4.6.2 on a
x86_64 system.

I would recommend file sources, you can filter, graph and demod them
w/o hardware.

According to Ettus official page:
https://www.ettus.com/product/details/XCVR2450
The range is 2.4GHz - 2.5GHz, 4.9GHz - 5.9GHz Tx/Rx.
I am confused, does it means:
1) both the Tx/Rx freq range is 2.4 - 2.5 and 4.9 - 5.9. or
2) Tx freq range is 2.4 - 2.5, Rx freq range is 4.9 - 5.9. or
3) Tx/Rx freq
Having some issues with CGRAN right now and actively working on it. So if
you experience problems, hang in there.
The SVN repo should be working just fine, but having some web issues.
