DECODING OF NON-BINARY LDPC CODESDECODING OF NON-BINARY LDPC CODESA method is proposed for managing a parity-check node calculation unit of an error-correcting code decoder having a representation as a bipartite graph comprising at least one parity-check node, the parity-check node being configure...
The performance of nonbinary LDPC codes depends on various factors. In general, the larger the field size and the larger the block length, the better is the performance for nonbinary LDPC codes. Encoding of a general LDPC code can be done in almost linear time instead of quadratic time on...

For improved performance of binary Low Density Parity Check (LDPC) codes, we need to have the minimum distance grow fast with n, the codelength. However, the best we can hope for is a linear growth in dmin with n. For binary LDPC codes, the necessary and sufficient conditions on the ...
Performance of NB LDPC coded transmission strongly depends on the mapping of nonbinary symbols to signal constellation points. We obtain a random coding bound on the maximum-likelihood decoding error probability for an ensemble of random irregular NB LDPC codes used with QAM signaling for specific ...
