Hi everyone,
I am trying to implement simple FSK system with USRP and I am using two
USRP's each with one RFX2400 daughter card. I have tried fsx_tx.py and
fsk_rx.py which are available in gnuradio_examples folder. after using tune
to set the proper ferquency I was able to run transmitter and rec
Hi
I need to get USRP samples from Gnuradio to C++. Eric mentioned that
a fifo with usrp_rx_cfile is the best approach to do this. All the
examples that I see use file_sink. How should I use usrp_rx_cfile?
Is it just like usrp_rx_cfile(gr.sizeof_gr_comples,filename)? Then
just one more questio
Hi
I am new gnuradio and usrp. I installed and tested gnuradio and usrp. Usrp is
running correctly. I have 4x4 USRP. First of all, I want to perform 2x2 mimo
alamouti coding. Everybody may send any information about this?

Actually, yes. I noticed that it returns None in all of the other
working examples as well so I just assumed it wasn't the problem and
went back to work.
Oddly enough I was able to solve the proble
Y,
Have you looked through the code available in in the
gnuradio-examples folder? I t covers the basic of getting started
with the available blocks.
Also you might want to have a look at the simple gnuradio manual
which covers all of the available functions:

Thanks Jason.
I'm reading some example scripts in the gnuradio-examples folder, and I
particularly interested in the /gnuradio-examples/python/digital/tunnel.py.
What we are interested in is particularly in the MAC/PHY blocks. Do you know
in which directory under gnuradio-core we can find it?

I've added the framework for Altivec, and implemented
gr_fir_fff_altivec using it. This gives a speedup of between 1.8 and
3.0 depending on the type of machine it's running on. There's probably
another factor of 1.25 - 1.50 that can be obtained by recoding
dotprod_fff_altivec.c directly in assemble

I've added graphs showing Altivec performance.
The MP scaling on the PS3 is _much_ better with Altivec than with

You have to de-solder it. Optionally (in case you don't want to remove
the part, since it will be difficult to reinstall it), you could
install a jumper (zero-ohm resistor) or (better) a small 10pF

Hi
No need to reply to my previous post. I found that usrp_rx_cfile.py
is in the utils directory and that it just uses the normal gnuradio
file sink, so I'll use that to write to a fifo.
Thank you

My colleague Steve and I have been working with the inband receive
code in an effort to understand how the timestamps work. Specifically,
we have been printing the timestamps from the usrp_rx block while
running test_usrp_inband_2rx.cc in usrp/host/apps-inband. There is
some puzzling behavior that

Hi All,
I have been attempting to use a GNU Radio 3.1.2 Virtual Machine (guest
OS is Open Suse 10.2) kindly provided by Chiara De Dominicis, with the
USRP. Initial communications with the USRP were established, enough for
firmware download to the USRP. However when attempting to run an
