[Discuss-gnuradio] Random behavior?

2010-11-08 Thread Jakub Moskal
Hi, We are experimenting with two USRP1's (each with RFX2400) and noticed some strange behavior. We use the /usr/local/share/gnuradio/examples/digital/benchmark_rx[tx].py. We run it once and the number of corrupted/lost packets is rather small, say 0-2%. Without modifying any default values of

I just upgraded 10.04 to 10.10 and compiled gnuradio from git repository without any problems, thus I would just use instructions for 10.04. Jakub On Wed, Sep 29, 2010 at 6:55 PM, Arturo Rinaldi arty.n...@gmail.com wrote:  Are there any news about the pre-requisites for source build for the new

[Discuss-gnuradio] Modulation scheme change on fly

2010-06-22 Thread Jakub Moskal
Hi, I would like to be able to change modulation scheme and other parameters on the fly, from within a separate process. I'm using a modified version of the tunnel.py from the GIT repository, which instead of forwarding the packets to/from TUN/TAP device, acts as a CORBA server with registered

[Discuss-gnuradio] FEC

Hi, I'm using the digital/benchmark_*.py from the GIT repository and am getting a very low ratio of corrupt packets, usually under 0.5%. I use the default gmsk modulation, USRP1's with RFX2400 and run the benchmark with a frequency of 2.4G. Would this low ratio suggest that the FEC is being

Hi everyone, I am trying to use the GNU-Radio+USRP to implement a cognitive radio use case in which radios exchange information (XML-based documents) between each other in order to achieve a defined goal (e.g. to improve connectivity), without disturbing the usual communication. I have several

Hi Michael, my intention is to allow a communication between two USRP's hooked up to two different computers. Each USRP has one RFX2400 daughterboard and one antenna connected to the Tx/Rx port. I have a more of a CS than ECE background and my focus here is on the application level. I would like

Hi, I've been browsing through the mailing list archives to find some examples of simultaneous rx/tx but with no luck. I have two USRP's, each equipped with RFX2400 and one antenna, attached to TX/RX. I would like these two radios to talk to each other in an asynchronous fashion - a radio can

Sheng, are you familiar with OSSIE project (http://ossie.mprg.org) ? It's an open source SCA implementation and they use USRP as their RF front end. Perhaps that could be a better place to start. However, I'm not sure what is your ultimate goal. Jakub 2009/4/2 sheng sheng...@yahoo.com: Hi,

Hello, I am debating whether to buy USRP or USRP2.. Is there any progress on the USRP2 drivers for the Mac OS X? It seems that the USRP2 FAQ hasn't been updated for a while - as far as this issue is concerned. Thanks, Jakub. ___ Discuss-gnuradio

[Discuss-gnuradio] USRP monitoring

Hello all, I recently installed gnuradio (3.2.x) on my machine (OS X) and was wondering about purchasing the USRP. It seems that usrp2 is currently only supported on Linux, so I guess I shouldn't get that one. Can anyone recommend daughterboards that would be best for simple communication, e.g.

Michael, thank you for help! It turned out that I had set the DYLD_LIBRARY_PATH for my Matlab, so that I could interface it with Java. Also, the PKG_CONFIG_PATH hadn't been set at all. After removing the DYLD_LIBRARY_PATH and setting the PKG_CONFIG_PATH I managed to compile 3.1 release from svn.
