This is the template for the [[:Category:Block_Docs|"Page-per-block Docs"]].  This first section should describe what the block does and how to use it, using however many paragraphs necessary.  Note that the title of the wiki page should match the block's name in GRC, i.e. the one defined in the block's .grc file.  Look at the [[FFT]] Block for a good example.


As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.

Inner coder with Puncturing.

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: Packed bytes (each bit is data). MSB - first, LSB last.

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

Parameters

Input length
length of input.
Output length
length of output.
Constellation type
type of constellation.
Hierarchy type
type of hierarchy used.
Code rate
Code rate used.

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.
