Has anyone already worked on this topic?
I'm currently working on it and I would have enjoy to discuss about it with people who have already work on it.

I'm currently working on this aspect. I would also enjoy to discuss about it!
What aspects are you working on? Decoding, encoding or construction?

In fact I would like to talk about decoding.
I've implemented Progressive Edge Growth algorithm and use it for binary LDPC codes so i will use it for non binary LDPC codes for the moment.
I will have a look to better construction as soon as I will have a decoder.
But there exist different decoder for non binary LDPC codes and I would have find great to have a feed back from someone who have already done a decoder for non binary LDPC codes.
Have you done a decoder? If so, which one have you chosen and why?
Best Regards,

I've just done the nonbinary LDPC codes, and did a little work on decoding and just set about doing FFT QSPA decoding algorithm.
I think that you can use FFT QSPA if u just want to test the performance of parity check matrice.
My research on constructions of H is mainly on structured constructions.
Which implementations have you used for simulation, matlab or C language? It took a long running time using MATLAB language for simulation? I consider using C language now. Could you give me some advice?
Thank you!

I'm currently working on it and I would have enjoy to discuss about it with people who have already work on or are working on it.
So anyone who want to disscuss this aspect can communicate with me!

i have the same feeling that it takes a long time to simulation using MATLAB.
now i am research the distributed source coding using non-binary ldpc codes.
