Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
This flowgraph can be found at [https://github.com/gnuradio/gnuradio/blob/master/gr-dtv/examples/dvbt_tx_8k.grc].

Bit Inner interleaver. See ETSI EN 300 744 Clause 4.3.4.1

Data Input format:

  • 000000X0X1 - QPSK.
  • 0000X0X1X2X3 - 16QAM.
  • 00X0X1X2X3X4X5 - 64QAM.

Data Output format:

  • 000000B0B1 - QPSK.
  • 0000B0B1B2B3 - 16QAM.
  • 00B0B1B2B3B4B5 - 64QAM.

bit interleaver block size is 126.
