Hello list,
I would like to announce additional daughterboard support and API
changes in regards to the UHD. As of this announcement, all Ettus
hardware is supported under UHD.

Daughter board features and support
You don't need to set a receiver subdevice if you are loading data from
a file. You will also need to set a decimation so the software knows
what rate to expect in the file. So, if your recorded data is at 1Msps:
./ais_decode.py -d 64 -F signal_filename
I know it's sort of weird to specify a deci
Hello,
I've been getting a series of underruns when running a USRP2 at 10MHz
(Interpolation = 10) using RTS and a fast machine. I plugged a serial cable
into the UART and can see one or more 'U's pop up on the screen. Depending
on how many custom blocks I have, the occurrence of a U can take from

This mailing list is only for discussing GNU Radio related topics. We
have another list for users of USRPs with other software like Simulink
and Matlab, which would be a better place to ask your question. You can

Hi all,
I am interested in using the new simulink block in the communications
blockset for the USRP2 receive in MATLAB. However, I wish to syncronise
multiple boards together using an external 10MHz clock reference and 1PPS
signal. I assume that I can do this by making some modifications to the U

Looks like it's working. Can't verify at the moment.
I think I saw recorded AIS signals somewhere in the web. Should be able to
test package with one of those (if I can find them again).
Should be something like './a
Hey list,
I regularly encounter underrun messages when running the UHD transmitter
(uhd_mimo_sink or uhd_simple_sink) with sample rates of 12.5 MSps or
higher. The OS (Ubuntu 10.04, 64bit) setup is according to the
guidelines (realtime priority for user, buffer size set to recommended
50 MB)
Oh, found where problem was.
Gnuradio is installed into usr/lib/python2.6/dist-packages/gnuradio
AIS package was installed into
usr/local/lib/python2.6/dist-packages/gnuradio
Could this happen because I used sudo su before downloading and installation
of package?
I'll try and reinstall, hope th
Benchmark_ofdm_rx.py program uses C + + functions OFDM?
Is there any way to see a python code in graphical form? as block diagrams
or something?
Using c++ there is a function you can use on the flow-graph object called
"dump_flowgraph()" or similar. Look in the doxygen documentation for the obj
Hi all,
I am implementing a GPS receiver based on the USRP2 with a DBSRX
daughterboard equipped, whereas the software is only using the URSP2 C++
interface, the rest is done without GNURADIO.
The receiver works quite well, but I noticed that whatever I do I get
really huge spurious signals in
Hello,
I am working on OFDM.
I have several questions about OFDM codes, and in general GNU radio.
As I understand, there are functions in C + + that are linked through
python, right?
if I look on the web:
http://www.gnuradio.org/doc/doxygen/
I can find the C + + blocks there for OFDM: gr_ofdm_bp
You can install various gcc versions in parallel without problems. But
I suggest to use the gcc from the repositories. Just search for it:
"zypper search gcc", and in your case, where the machine has no
connection to the internet, just download the appropriate rpms from
the "openSUSE:11.3/standard"
I build bpsk process on gnu using costas loop. But I don't know how to set
'alpha' parameter. Now I change it and fc min ,fc max by hand.
Thanks
