Daniele, this is interesting. However, I'm not 100% clear about the implications this would have (i.e. which changes are necessary). Is it just the build flag, and then of course the accompanying limitations listed in the manual (those would not be a problem, as far as I can tell)? One thing I ca

[Discuss-gnuradio] Transmitting bursts with GRC by inserting SOB and EOB

Hello, I am trying to implement a burst transmitter using GNU Radio Companion and an USRP N210 with WBX board. My problem is when inserting zeros as "gap" between the bursts the USRP is transmitting a non-neglectable carrier signal (due to DC offset I guess?). So I want to try inserting tx_so

Another question. I have a GPS receiver ( http://u-blox.com/images/downloads/Product_Docs/LEA-NEO-6T_ProductSummary_%28GPS.G6-HW-09020%29.pdf ) with a Osmo board ( http://openbsc.osmocom.org/trac/wiki/osmo-lea6t-gps ) Can I directly connect the USRP (WBX) to the GPS receiver? Can I damage the WBX

Vlad, thanks for going through the guided tutorials, and thanks for your feedback. We'll address those soon and fix the tutorials. As for your solution, I'm not sure. I recommend putting a couple of print statements so you can tell what's going on. cheers, M On 10/20/2014 10:06 AM, Vlad Stoica

Re: [Discuss-gnuradio] Transmitting bursts with GRC by inserting SOB and EOB

A couple of comments, maybe this helps you on your tracks: - You're using an ancient UHD version. Is there a reason you can't use a newer one? - In current GNU Radio, you can use 'length tags' to mark bursts, if that's any help. - You'll know if your USRP hasn't acknowledged tx_eob if you see 'U's

Have you tried the OpenBTS mailing lists? OpenBTS is *NOT* a Gnu Radio application, although it uses the same hardware as some Gnu Radio apps, it's not a Gnu Radio app itself. On 2014-10-20 15:15, Mostafa Alizadeh wrote: > Hi all, > > Is there anyone who used OpenBTS-UMTS [2] with USR

No, I didn't try OpenBTS mailing list, but I think this is possible to run the BTS over USRPs with some specific UHD configuration. Thank you for your hint. OpenBTS isn't even a GNURadio app. Did you try it? On Mon, Oct 20, 2014 at 3:17 PM, wrote: > Have you tried the OpenBTS mailing lists?

Re: [Discuss-gnuradio] OpenBTS-UMTS

Hello Mostafa Alizadeh: OpenBTS and OpenBTS-UMTS do not use the GNU Radio framework at all, and so you don't need to install GNU Radio in order to use them. To use OpenBTS and OpenBTS-UMTS with USRP radios, you will need to install UHD [1], which you should install before installing OpenBTS and O
