This paper addresses the problem of decoding non-binary low density parity check codes
(LDPC) over finite field GF (q) using symbol flipping approach. To achieve low complexity …

The paper introduces two decoding techniques based on grouping for symbol flipping non-
binary LDPC codes. Firstly, a new technique of adaptive grouping of variable nodes in each …

In this article, two algorithms for improving the bit error rate performance of the non-binary
LDPC codes over higher order modulation are proposed. The first algorithm is the predictive …

This paper introduces an adaptive technique for grouping variable nodes in decoding non-
binary LDPC codes that involve symbol flipping. The technique considers both the individual …

Channel coding is an important and integral part of transmission and storage devices of
digital information. All communication systems depend on how precisely receiver can …

LDPC codes improve error correction performance in soft-decision decoding by using the
reliability of the received signal, offering greater accuracy than hard-decision decoding. The …
