Neither of these implementations is even remotely fast enough for real-time
applications. There are a few open-source fast LDPC decoders that take
advantage of modern processors. The real stand-out is the one by Bertrand Le
Gal (https://github.com/blegal/Fast_LDPC_decoder_for_x86). I have don

Hi Johannes,
you don't happen to have first-hand experience with that library?
Best regards,

Hi Sylvain,
thanks for you thorough look into the state of the LDPC encoder/decoder.
I just skip the long text of wall and answer your questions from my
point of view:

I personally would like to see the FEC module cleaned
Hi all,
I've spent the last day trying to understand the state of LDPC
encoding / decoding in GNURadio, to see how it could be improved. I
limit myself here to gr-fec and not the application specific ldpc that
can be found in gr-dtv for instance.
Here's what I think is the current state (please,
