freeze tetrapol-tx
by fe8769 23 Jun '23

23 Jun '23

Hello We have trouble using tetrapol_tx with gnuradio 3.10/3.11 . Transmit is freezing for non reason . Hackrf is the latest firmware version . Working fine with codec . Working fine with gnuradio 3.7 . Sometimes it works fine without freezing but most of the time we have to restart . Could be helpful for us to transmit with the limesdr mini first version,plutosdr and ettus B200. Thanks for help --

Viterbi algorithm
by guerlande 12 Jul '21

12 Jul '21

Hi ! Here is a first version of an error-correction using a Viterbi algorithm, which correct more errors than the current frame_fix_errs(). I put a limit on the errors (if there are too many errors, we suppose that the frame is broken, otherwise too many "random packets" are considered valid, since the CRC control has only 3 or 5 bits).
