Why not try GNU Ocatve to get a feel Matlab? Last time a played with Octave, I
believe it was directly compatible with most *.m files from the base Matlab.
Of course Matlab has all the toolboxes.

There is also LabView, which has much more DSP blocks than the base Matlab, and
also works with the USRP2 and N210.

Hi folks,
I assume it's possible for the B210 to listen to GPS. (Correct me if
I'm wrong.) Rather than paying for an expensive GPSDO, are there any
technical limitations in using one MIMO channel of the B210 for, say,
OpenBTS, and the other MIMO channel as a replacement for a GPSDO?
Excuse my ignorance if this is an under-thought question.
Thanks,
Jason

Hi Jason,
the primary function of the GPSDO is not being a GPS receiver, but a
GPS-derived disciplined clock. So it's nothing you can do in software
- -- there is actually a disciplined oscillator (hence the name) that
you use to improve your USRPs frequency accuracy; this has to be done
in hardware.
Anyway, if you 'just' want to do GPS, then sure, technically this
should be possible.
Greetings,
Marcus

Hi
Even if this thread is pretty old i am gonna reply now.
I had the same issue on a lenovo (and another notebook).
For me it turned out that the connection only could not be established
if the notebook runs with the power adapter connected.
best regards
G?nther Hutter

You could use the b210's radio to listen to gps, but the 2nd channel would
then be forced to be on the same frequency. So unless your intended use is
gps it is impractical.
