In this letter, we address the problem of decoding nonbinary low-density parity-check
(LDPC) codes over finite fields GF (q), with reasonable complexity and good performance. In …

Despite the outstanding performance of non-binary low-density parity-check (LDPC) codes
over many communication channels, they are not in widespread use yet. This is due to the …

Low-density parity-check (LDPC) codes are playing more and more important role in digital
broadcasting standards due to their excellent error correction performance. In this paper, we …

We propose a non-binary stochastic decoding algorithm for low-density parity-check (LDPC)
codes over GF (q) with degree two variable nodes, called Adaptive Multiset Stochastic …

Nonbiliary low-density parity-check (LDPC) codes can lead to excellent error performance
while the codewords are of short or moderate length. However, the high decoding …

Combination of overlapping pulse position modulation and pulse width modulation at the
transmitter and grouped bit-flipping algorithm for low-density parity-check decoding at the …

GF (q) 域上非规则LDPC 码是二进制非规则LDPC 码在有限域GF (q= 2p) 上的扩展,
在码长和码率相等的情况下, 具有比二进制非规则LDPC 码更优异的性能. 如何分析GF (q) …

This paper introduces a novel concept for exploiting low-power edge graphics processing
units (GPUs) for decoding higher-order non-binary low-density parity-check (LDPC) codes …

Several authors have developed a Hadamard (variously called FFT) transform technique for
fast belief propagation over GF(q), where in all prior work q=2^m for some m. The belief …

通过分析扩展最小和算法(EMS) 存在的问题, 提出了一种针对q 元LDPC 码的改进译码算法.
不同于EMS 算法固定每次迭代中FHT 的阶数, 该算法根据每次迭代中变量节点的概率分布对的 …
