Re: [Discuss-gnuradio] GRC squelch block with separate control signal?

Hi John et al, First, my apologies for waking up this very old thread. Only the other night I had one of those "lightbulb" moments, as I have been trying to implement something similiar for a while myself. On 07/09/11 12:58, John Ackermann N8UR wrote: Tom Rondeau said the following on 09/0

[Discuss-gnuradio] Updating the BBN_80211

Hi all, I am new at the GNU Radio and UHD Fields. I have recently begin to make some modifications at the bbn_80211 code (which is compatible with the GNU Radio's 3.1.1 release) to make it run with uhd and USRP N2X0. But when modifying the "bbn80211.py" import section "from gnuradio import usrp

Hello all Thank you very much for such prompt response. @Marcus: I understand the problem now and will try to implement the Rx and Tx on different USRP on Monday. The weeekend has already started here in France. @Andrew: I will also get back with exact result of the commands but what I remember fo

Re: [Discuss-gnuradio] How to synchronize two transmitters

Thanks for the reply! If I use one computer, I would even combine and stream them to the same USRP antenna. What I wanted to have is two independent transmitters ( primary and secondary) transmitting over the same channel. The secondary (cognitive) transmitter will have to synchronize to the primar

Type " uhd_find_devices " into console, then " uhd_usrp_probe " then give us the results, and the code for the program you're trying to run. On Fri, Jan 27, 2012 at 9:39 AM, shashank gaur wrote: > Hello > > I am simply trying to build a transmitter and receiver for bpsk modulation > and demodulat

[Discuss-gnuradio] which architecture is used for SIMD optimized math blocks of gr-blocks

Hi Josh, I see that there are some work on the SIMD optimized math blocks in gr-blocks. I am wondering what kind of computer is used for your test regarding this SIMD optimization. Best Regards, Changchun (Alex) Zhang Cognitive-Radio Institute@Tntech <>__

Re: [Discuss-gnuradio] How to synchronize two transmitters

What I think that might be a solution is using only one computer with two USRPs. In the flowgraph, you will have two sinks. If your network card are both identical and the distance between the USRPs are not large enough to be considered, I don't see why the signals would not be syncrhonized (or, at

Hi everyone, gr_modtool.py has undergone some heavy revision recently. It'll now do even more stuff: * It's been changed to the CMake version. The autotools version still exists on the CGRAN SVN server. * You can create out-of-tree modules using 'gr_modtool.py create'. This is basically an im

Hello I am simply trying to build a transmitter and receiver for bpsk modulation and demodulation using mpsk receiver at receiving end. I am using USRP1 (Flex900 Daughter boards))with Gnuradio Companion 3.5.0rc0 on Ubuntu 10.10. When I run either (trransmitter or receiver) of any grc applications
