Hi all, would it be an option to add a specialized library to GR for LDPC code? 'aff3ct' [0] would be one library that comes to my mind. Of course, they might have a different approach to decoders in general. Also, at this point this might be a "compile your own dependency" library. Anyways, it might be worth to have a look at it.

I didn't find an OpenEmbedded recipe for M4RI, but a quick look at the source suggest it will be easy enough to create a recipe. Give me some warning if you go this path and I'll work on the recipe.
