Dear Saleh Alkarim 

Thank you very much

Hello Waheed,

I also suggest review this thesis and paper

Conference Paper Flexible non-binary LDPC decoding on FPGAs

Dear Dr.Eduardo Avendano Fernandez 

Thanks 

is trellised based Min-Sum NB-LDPC  has some capacity for further research ? what is the good to way fo NB-Decoding ? pass all information as symbol (nonbinary) or a binay word(bit by bit) ??

regards

Waheed

Have you read this paper?

http://ieeexplore.ieee.org/document/6516166/

On the other hand, there is a paper on coded modulation from  where you can find a comparison of different coding for multilevel modulation schemes, where non binary, polar and others are considered.

L. Beygi, E. Agrell, J. M. Kahn and M. Karlsson, "Coded Modulation for Fiber-Optic Networks: Toward better tradeoff between signal processing complexity and optical transparent reach," in IEEE Signal Processing Magazine, vol. 31, no. 2, pp. 93-103, March 2014.

Also from Ivan B Djordjevic you can see that LDPC continues offering a good performance against NL effects in optical communications, and https://scholar.google.com/citations?view_op=view_citation&hl=es&user=dPfqhb0AAAAJ&sortby=pubdate&citation_for_view=dPfqhb0AAAAJ:IyMil-iDmu0C

A best paper award last year where experimental evaluation using LDPC for higher capacity show results

Thanks Eduardo Avendano Fernandez . I will check
