Hi,
1.Any one can tell me in gnuradio OFDM, after ofdm_sync block, what are the
data looks like?
2. Does the output go through FFT operation already?
If not, when does the FFT actually actually come ? Does it after the
ofdm_sampler block?
If yes, how can I actually get these data? And, how can I
Is anyone here upgrading to a USRP2, and interested in selling their used
USRP?

Hello,
I recently purchased a USRP2 and have been trying to find the
documentation/examples on how to use the PPS functionality to timestamp
received data (with the PPS connected to a 1sec trigger source). So far, I
have not been able to find any examples of using this functionality. If I am

Thank you Marcel for mentioning that "little" detail: before trying
MacPorts out, if it's already installed, you'll want to do what he
wrote below in order to get the latest portfiles w/ patches & such.
Hopefully that will solve your issue Kunal; if not, let me know.
% sudo port selfupdate
I had the same error, but by upgrading port and cleaning gnuradio this error
went away:
% sudo port selfupdate
% sudo port upgrade outdated
% sudo port clean gnuradio
% sudo port install gnuradio
After that it somehow still tries to install wxPython and will halt with
this error:

If they are different, is the frequency tuning range different?

Hi,
As another OS X + GNU Radio user, I really appreciate your efforts! I tried
running "sudo port install gnuradio" on my MacBook Pro running 10.6.2. It
fails with the following error:
libtool: compile: /usr/bin/gcc-4.2 -DHAVE_CONFIG_H -I. -I../../../..
-DOMNITHREAD_POSIX=1 -I/opt/local/in
That's awesome work you guys are doing Johnathan! Hopefully I will
soon have the time to build the neccessary hardware and give gr-noaa a
try.
Please keep up your great work!
All the best,
Markus

Thanks for the suggestion. I tried wireshark. I didn't see any packages
going out when I called "sudo find_usrps". How do I make sure gnuradio is
installed properly? The installation seemed to go smoothly, and I am able to
run grc (gnuradio-companion).
Thanks,
Omid

I've checked in MacPorts modifications that should allow for
installing GNU Radio 3.2.2 via MacPorts on 10.5 (Intel or PPC; 32 or
64 bit; "universal" too) or 10.6 (32 or 64 bit, except for gr-wxgui
since it relies on wxPython which doesn't have a 64-bit compatible
version yet; wxWidgets 2.9
Hi,all
I need to do a ber test and my current system is based on frequence hopping.
I think I should send a random 01 bit sequence at the transmiter side and
then,obsever the received bit sequence.
In next step,when campare the two sequence in order, how decided the
order?or how to do the Sync in

Hi everyone
I'm a student from the University Miguel Hernandez (www.umh.es). I'm

machine). I've been reading for a while the mailing list, and some
