Nonbinary LDPC codes outperform their binary counterparts in different scenarios. However,
they require a considerable increase in complexity, especially in the check-node (CN) …

This paper constructs an objective function for symbol flipping decoding algorithms,
considering not only soft reliability, but also hard reliability. The maximization of this …

During the check node (CN) update, the elements of input message vectors are redundant
for the output message vectors. Hence, in this paper, we exactly select from the input …

In the check node (CN) update of non-binary message-passing algorithms, each element of
reliability vectors takes the same computational complexity. However, our analysis indicates …

In this paper, a method to approximate the second minimum required in the computation of
the check node update of an LDPC decoder based on min-sum algorithm is presented. The …

Nonbinary low-density-parity-check (NB-LDPC) codes, an extension of binary LDPC codes,
provide stronger error-correcting capability than binary LDPC codes. However, the …

In this brief, a novel two-extra-column trellis min-max algorithm and the decoder architecture
based on only the first minimum values are proposed for nonbinary low-density parity-check …

The weighted bit-reliability-based (wBRB) algorithm for nonbinary LDPC codes suffers
certain loss of symbol-reliability. Thus, this paper enhances its soft-decision version by …
