Viterbi Decoder

DVB-T Viterbi decoder.

ETSI EN 300 744 Clause 4.3.3 Mother convolutional code with rate 1/2. k=1, n=2, K=6. Generator polynomial G1=171(OCT), G2=133(OCT). Punctured to obtain rates of 2/3, 3/4, 5/6, 7/8.

Data Input format:

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

Data Output format: Packed bytes (each bit is data).

       MSB - first, LSB last.

Parameters

Example Flowgraph

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.
