Josh,
I committed a nice little example that uses grc and gr-trellis:
(it is an example of interference cancellation in a multi-user system).
It is in grc/examples/trellis.
Could you please make the appropriate modifications in the
makefiles/config files; don't know how to do that yet...

Hi,
I have not test it yet. But did you followed Eric suggestion in this
thread!. change every (self.u.set_interp_rate(xxx)) with:
self.u.stop()
self.u.set_interp_rate(xxx)
self.u.start()
Best regards,
Firas

Hi,
If you want to use gnuradio in your sound work only (not doing any RF work), I
dont think you will need the USRP. All what you need is your PC sound card and
the gnuradio software.
Best regards,

I changed my code to set the interpolation every 10 packets instead of
per packet. Now the program doesn't block any more.
But now the problem is the transmitter can't transmit the data
correctly, that is checked by bechmark_rx.py and usrp_ffy.py

It looks like you are both using the wrong software. For transmitting,
use usrp2_siggen.py and for receiving use usrp2_fft.py.

There is no distinict pattern. How I am working it out currently is;
when the error apears, I turn the USRP off and turn it on again. In that
case, it works mostly. But, I was

You can checkout the gnuradio trunk
./configure
cd grc
make
sudo make install
This is better than making then entire tree again, but you would still
have to run configure and make sure that most dependencies are
installed Which probably just means that you have to install gsl and

Hey all,
I have already installed Gnu radio before. But, because I am new to gnu
radio, I have not installed all the important components.
Now, i want to install GRC. I see that there is GRC folder in the gnu radio

$ svn co http://gnuradio.org/svn/gnuradio/branche
