Iso image of Ubuntu+Gnuradio installed inside a vmware player ... is this
what you want ? Its easy and you can make by yourself :)

I have a quick theoretical question. Is there any way to construct an
8-channel receiver using 4 USRPS without data going through the host
computer? Basically some kind of way to daisy chain mimo cables (though I
know this is not possible), or at least get the same benefits you would
receive from d
Clarification: This would be using USRP N210, not USRP1, where I know it is
possible to have an 8 channel receive or transmit only using a mimo cable.

Dear gr / USRP fellows,
I'm currently experimenting with USRP B100 Local Oscillator relocation time.
I've done some experiments on the RX path by tuning towards and away from
an OFDM beacon signal.
I have flushed into the received signal some recognizable "relocation
marks" which allowed me to an
Hey list,
For those who were not at the GR Conference 2012: I presented some work
demonstrating a simple ARQ MAC over TDMA; using GNU Radio and USRPs in
GRC. Its very cool work, I encourage anyone to take a peek at the
slides, and checkout the repo and run the examples.
The MAC layer work is actu
You can use a gigabit ethernet switch and put all the USRPs on there.
You should be able to make USRPs send data to each other. You will of
course need to do work to get your algorithms into the FPGA.

Hi Josh,
A quick question, what is the time reference you are using for the TDMA
engine? Is it GPS or something else? How accurate about the time
synchronization?

In this case we tested in the LAB with shared reference and PPS. GPSDO
per USRP
One should remember the extremes involved in syncing all USRP'S which will
lead to developing a new driver for USRP2.
What about the your APP development time?. Are you interested in developing
new driver or app ?

This system used a 1PPS to sync the radios - for the sake of getting it up
and running quickly. A GPSDO would work just as well, with ~50 ns of
accuracy, which is pretty good.
Alternatively, as Josh said, you could synchronize the radios with other
methods, like over-the air broadcast of a "syste
Hi,
I'm trying to synchronize two N200s in phases with both of them having
GPSDO inside. I followedthe instructions on ettus for synchronizing channel

Dear all,
I find the sampling rate of USRP is surprisingly accurate.
Now I set the sampling rate as 4 MHz, and there are always exactly 4M points
between two pps signals.
Even if I take off the GPS antenna, the sampling rate is still very
accurate.
This means I only need the GPS antenna at t
