A repetition decoder class. This takes a majority vote, biased by the ap_prob rate, and decides if the number of 1 bits > ap_prob, it is a 1; else, it is a 0.
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.

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.

A repetition decoder class. This takes a majority vote, biased by the ap_prob rate, and decides if the number of 1 bits > ap_prob, it is a 1; else, it is a 0.

Parameters

Parallelism
Dimension 1
For paralelism
Dimension 2
For paralelism
Frame Bits
Number of bits per frame. If using in the tagged stream style, this is the maximum allowable number of bits per frame
Repetitions
Repetition rate; encoder rate is rep bits out for each input bit.
a prior prob
The a priori probability that a bit is a 1 (generally, unless otherwise known, assume to be 0.5).

Example Flowgraph

This flowgraph can be downloaded from Media:Fec_coder_test.grc.
