Hello,
I have modified gr_constellation_decoder_cb.cc in order to have a second
output stream (type float) sending back min_euclid_dist.

Please take a look and let me know if there are any
Hi,
i try to see the modulation of every carriers with the option log, but when i
put this options the is this errror :

Hi,
i've done the simulation, but i've a question. In the graphs the program did,
the are, in the constellation rappresentation, blue and red points. What do
they rappresent?
thanks a lot

Hi again,
Can I assume the following? : because I am using the USRP, if when adding
the printf I do not get any under-run everthing is OK (i.e. the behaviour is
the same with and without the printf's) ?
Thanks!

Hi All,
Irene,
I believe the problem is that you are trying to have two different
types of output streams. According to the documentation on
gr_io_signature, it looks like multiple output streams must
all be of the same type. Or at least of types that have the
same size.
In your code, you try to

I am currently trying to get some basic code working to test that my
shiny new USRP is working correctly. I have been going over the
code/examples/list archives for a few weeks on and off, but most of
the code examples are for the basic RX/TX boards, and I only have two
RFX2400's.
My testing

Yeah, that's a bit confusing and a good question.
Hi List,
Just re-stating the issues I am having with capturing IF samples of an RF
signal: I am trying to sample a 16MHz wide spectral content from a signal,
originally centered at 2.414 GHz. I am using RFX2400, gnuradio 3.1.2 and using
following command:
python usrp_rx_cfile.py -f 2404.5M

Arrrgh! Apologies to all. I totally missed the all-important 2
at the end of Irene's gr_make_io_signature2 call. Please ignore my
previous post.

How do you _know_ you're not getting +/- 8MHz?I am looking at the signal
spectrum in Matlab. The window shows me, I belive, -Fs/2 to Fs/2.
