Dear UHD developers and all,
I hope you don't stop reading this because it's about the obsolete
VRT-branch. It may apply to UHD as well.
Everything I have tried with the VRT-branch has worked until today.
This is nice because I have been looking for the transmit at time t
functionality for
Hi,
we've done some work to our 'Spectral Estimation Toolbox' and added
Burg's algorithm for spectral estimation. It's all on CGRAN, see

Things aren't 100% perfect, probably due to the high number of
multiplications numerical accuracy is sometimes a bit off
The problem seems to be solved.
I need to set the header to:
hdr.header = VRTH_PT_IF_DATA_NO_SID | VRTH_START_OF_BURST |
VRTH_TSI_OTHER | VRTH_TSF_REAL_TIME_PS;
where TSI seems to mean time stamp seconds and TSF mean time
stamp fractional seconds. The unit is in tics of the 100MHz
Hello everyone, I'm trying to capture a signal with the USRP board and save
it into a file using the script usrp_rx_cfile.py. When I try to run the
script I get the following error:
File ./usrp_rx_cfile.py, line 16, in module
class my_graph(gr.flow_graph):
AttributeError: 'module' object

Hi
I'm trying to make a very simple hier block. ( see the code below). When I
execute my top block i get no error, but the data seems to never enter the
hier block ( the print-line prints : ()). What am I doing wrong?

I hate to post yet another install issues thread, but I'm stuck for the moment
here. During make, I get the following error:
make[5]: Entering directory `/home/shared/gnuradio/gnuradio-core/src/lib'
/bin/bash ../../../libtool --tag=CXX --mode=link g++ -g -O2 -Wall

Thanks John and Matt for your answers.
Indeed Matt, in my band of interest there is DTV signals since I'm trying to
record them !! :).
Unfortunately, i can't put the enclosure because the SMA connector is to big
to close the box. Indeed the MCX to SMA bulkhead connector wasn't in my
package

Hi all,
I'm poking around the USRP2's CPLD, the XC9572, mainly just to
understand exactly how the U2 boots, and so looking for the Verilog

This is good stuff; thanks for sharing!
If you don't mind, I am curious of your experience of the Burg versus
The question: Has anyone gotten benchmark_tx.py (or tunnel.py) to work from
USRP2 to USRP1?
I have built a fairly in-depth CSMA/CA MAC on top of the simple carrier
sensing in 'tunnel.py' to test the performance in some protocol variations.
My setup works great with the USRP1s which I designed

I've done ./configure and specified the boost location as you suggested,

Have you considered and rejected Pisarenko estimtion techniques or just not
tried them yet?
Thank you for your efforts
