Re: [Tetrapol-kit] RP-CELP decoder doesn't seem to work

Ah, I thought that you use our online decorer at http://nat.brmlab.cz:8064/. If you are using software rp-celp implementation, it is expected that it doesn't work, as the codec is not yet fully implemented.

RP-CELP decoder doesn't seem to work
by Helio Machado 15 Mar '16

15 Mar '16

Hi! I'm testing the latest tetrapol-kit with a TETRAPOL signal (formerly known as SIRDEE here in Spain). I capture well, and decode to JSON, but when I use the rp-celp codec to extract audio, I only get weird sounds. I don't know if I could send you a sample. crushedice2000 +=|at|=+ thatmailofgoogle . com Thanks in advance. Helio. -- Un saludo. Helio.

bit allocation in VOICE frame found
by JS 19 Jan '16

19 Jan '16

Hi, good news for everyone, we have identified bit allocation for individual parameters in VOICE frame. There is still few thinks to find out (gain value conversion, size of subframes, LAR conversion), but the way to implement codec is now a bit more narrow. I want to say thanks to all who made this possible. With best regards, JS.

detector_01 branch
by fe8769 20 Sep '15

20 Sep '15

I had tried to test : in branch detector-01 is new tool with automated channel detection. It should not suffer the bug known from run.sh tool and should work with latest distribution GnuRadio. This is preliminary version, it will be modified and refactored lot in future. I did git clone http://brmlab.cz/git/tetrapol-kit.git then git checkout -b detector-01 then cmake .. and make no detector.sh in demod directory I tried git pull : no result I m so bad in linux --

new automatic channel detection tool
by JS 14 Sep '15

14 Sep '15

Hi, in branch detector-01 is new tool with automated channel detection. It should not suffer the bug known from run.sh tool and should work with latest distribution GnuRadio. This is preliminary version, it will be modified and refactored lot in future. usage: - build tetrapol-kit using instructions from README - goto demod directory - edit tetrapol_detector.sh as needed (now set-up for rtl-sdr and 393MHz band) - run ./tetrapol_detector.sh (now takes 30 sec samples) - see results in demod/tmp directory (.log files) JS
