Hello, there is now a test sample (bit file) with speech at http://tetra.osmocom.org/trac/wiki/Test_Samples Please only add samples to this page if you have the full agreement for publishing from all involved parties (e.g. operator of the network, people speaking during the capture). This is not the place to share captures which were made from someone else without their knowledge. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

osmo-tetra make error

by sinager＠tarapippo.net

Hi, I just upgraded my box to Ubuntu 11.10 and successfully compiled GNURadio 3.4.2, however I'm unable to build osmo-tetra (output below). I had it working on my Ubuntu 10.10 box with GNURadio 3.1 or 3.2 (can't remember exactly now). The latest libosmocore has been compiled and installed. Trying to get closer to the issue I also experimented with the libosmocore/osmo-tetra source versions available when I made the successful install, but I'm getting the same error. I'm not sure whether I'm simply missing some step or I'm facing an incompatibility. Any hint?

[ANNOUNCE] First OsmocomGMR code release

by Harald Welte

First Osmocom GMR code release As some of the readers may already know, a couple of Osmocom developers have been working on a new sub-project: OsmocomGMR. The primary goal of this project is to provide a reusable and clean implementation of the various layers of GMR-1. What is GMR-1 ? Well, it stands for "GEO Mobile Radio" and it's a set of specifications describing a satellite based mobile phone network heavily inspired from GSM. One of the major commercial operators of GMR-1 technology is "Thuraya", providing coverage over Europe/Africa/Asia/Australia. So far the implementation focused on the lowest layers: * Physical layer with FCCH sync and demodulation support for * pi4-CBPSK and pi4-CQPSK bursts. * Channel coding layer (scrambling/puncturing/convolutional coding/crc/interleaving/...) And some ancillary tools to exploit those: * A good capture tool to listen to particular ARFCN(s) and channelize them properly * Wireshark support (BCCH only so far) The first 'demo application' using all of the above provides functionalities similar to what airprobe is for GSM: An air interface protocol analyzer that goes all the way from capturing data off-the-air to sending packets to wireshark for analysis. Limited to BCCH only currently but this will evolve with time. Development was mainly done by Sylvain Munaut, with help from Dimitri Stolnikov (early signal captures and his great capture tool), Harald Welte (initiating the project) and Steve Margraf (testing different setup and antenna ideas). If you'd like to know more, you are encourated to read the wiki (http://gmr.osmocom.org/) and join the mailing list (http://lists.osmocom.org/mailman/listinfo/gmr) -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

About speech decode...

by Eddy

Dear All.. Finally I can use OSMOCOM-Tetra to decode some Tetra signal by Wireshark. But I have met some problems when speech decode the files on the mailing list. 1. It's always show "0 Channel Frames processed ie 0 Speech Frame" message when I input a bits file(whatever converting from OSMOCOM-Tetra or download from the mailing list providing) to "cdecoder" program.(Of course it will output a useless "blank file".) 2. I tried to input the sample bits files into "sdecoder" program and it can convert a PCM file. If I use some playback programs include aplay(-f S16_LE) to play the PCM file, there's no any readable speech. Does anyone can help me to check this? I don't know what point I missed. Thank a lot! Best Regards Eddy.

U-RFX board: someone has already tried it?

by Luca Bongiorni

Hi all, i was wondering if to buy one U-RFX, with the aim of testing it with various projects. Considering that: - are fully compatible with USRP [1]; - are seen as the useful WBX; - i don't have yet a WBX... that would be the perfect substitute for the WBX (imho). Someone has already tried it? Impressions?! [1] http://www.ruby-forum.com/topic/1266576 Cheers, Luca. P.S.: I apologize for the cross-posting.
