hi all,
I have made a simple program for sine transmission which is just a
replicca of usrp_siggen. Im successful in transmitting a sine wave
with the help of side A of usrp1, but when i want to transmit it by
side B, it doesnt give any error but it doesnt transmit either...
My code is given as:
Hi! Now it works! Thank you so much!

Hi Tom,
Thanks for the reply.
In the ofdm_sync_pn.py, I see that a matched filter is used, after the
timing metric is obtained based on the correlation of the two halves of the
preamble. I understand this matched filter is trying to find the end of the
plateau of the metric and get the smooth peak

Yes, there is a demo video on this from 2010 which you can view at my
youtube channel http://www.youtube.com/user/wwvince1
It's called Soft-SFN.

Thanks Nick,
that's perfect.

Use a 5-10dBm reference with no DC component. This corres
Looks like there may be a bug in the PYTHONPATH finder inside
build-gnuradio.
This has almost zero downstream consequences, since
it's merely offering a suggestion as to what to set your PYTHONPATH to
in your .bashrc. It doesn't automatically edit your .bashrc--that's up
to you.
On Ubuntu 1
Try:
uhd_usrp_probe --args "type=usrp1"
Then
uhd_usrp_probe
--args "addr=192.168.10.2"
That should (assuming you have networking
setup correctly) give you probe outputs from both your USRP1 and N200.

Hi!
I have not managed to install what I wanted for my school project.
After gnuradio and uhd installation with the build_gnuradio script,
uhd_find_device found only usrp n200 but not usrp1...
I didn't have much time so I wouldn't touch anything in the first software. So
I would start writing t

Hi Vince,
Changing a little the topic, have you managed to run your SoftDVB code to
work on multiple USRPs in order to create a SFN DVB configuration?

Hi Nick, thanks for the answer.
Everything clear.
Just a further question.
Would a 0V-mean, 3.3V peak-to-peak sinusoid be correct as a reference
signal for the B100?

I assume you know what you're doing, but just in case someone reads this
