Thanks Eric, so the usrp accepts negative
IF¡¡frequency?

Hi Eric and Matt
When the input IF signal passes quadrature
downconverter, does any kind of carrier and symbol
synchronization is performed in the FPGA code? If so,
which algorithm did you use?
Thanks

I also use FC3, for wxPython, my way is:
from the download page:
https://sourceforge.net/project/showfiles.php?group_id=10718
download the following rpms
wxPython2.5-gtk2-unicode-2.5.4.1-fc2_py2.3.i386.rpm
wxPython-common-gtk2-unicode-2.5.4.1-fc2_py2.3.i386.rpm
wxPython2.5-devel-gtk2-unicode-2.5.4.
confusing to me, why we need to do
so?
Thanks very much for your time.

I am using Fedora 3, i586.
When you install Fedora 3, make sure you have selected
development tools and x-windows development tools.
Then I belive your life can be much easier.

By the way,
If I run nbfm_rcv.py, I got the same error. But if I
use --no-gui option, then the error won't appear. It
seems that this error is related tothe graphical use,
could any one of you give me any suggestions?

Hi, Eric
Toby's suggestion helped me solve the problem. If I
configure "without" the --enable-sse option, then
everything works well. Is --enable-sse option
necessary here?
Thanks to you guys

tried usrp_oscope, it works pretty well. But
when I zoom in, I found the wave form doesn't seem to
be sine, but something like square or triangle. Do I
miss any parameters here?
Thanks so much

So what happens? Is there anything wrong with my
setting? What can be done for a reliable transmission?

or? What's the
difference? Does it have anything to do with the
receiving side? If so, why we have to interpolate it
using FIR lowpass filter? Can we duplicate each +1 or
-1 8 times? i.e.
1 -1 1 1 -1 becomes
-1-1-1-1-1-1-1--1-1-1-1-1-1-1-1
Thank you very much for yo

Do you have any suggestion that we can improve the

increase the length of the synchronization bits? or
decrease the hamming distance?

Hi, guys
I've generated a BPSK signal (float), and want to send
it by the USRP. But the USRP sink only has two types:
_c and _i. So is gr_float_to_complex the correct
block I should use before sending the signal to the
USRP sink?
Thanks
uarantee this, but I am not sure whether GNU
Radio could gurantee this, especially when we split up
stream and recombine again.
Thanks

Has anyone met this before? Although the message

V--1V, but 0.1V - -0.1V, so that the
ADC can quantize the signal more subtly??
And how about the Tx path?

Hi, Rick
Would you please iterate more about why it's not a
problem for analog signal? Maybe some mathematics
would be very helpful to me. My understanding is if
the spectrum is reversed, the signal shouldn't be the
same.
Thanks
