[Tetra] burst detection/synchronization

Hi all, based on the output that Dieters' demodulator from the OP25 project, I have now written some (simplistic) code to detect the Synchronization and normal burst training sequences and to split the received bitstream into bursts. Based on the samples that I took here in Berlin some time ago, we get 724 bursts, all of them seem to have excellent training sequences - despite still using hard bits. The received bursts are split into their BLK1/BLK2/BBK components. However, as we don't yet have a viterbi decoder for the RCPC convolutional code, we cannot recover the actual Layer2 PDUs yet. The code is now in git, the README has been extended a bit to reflect the current state. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
