摘要

在这篇文章中,我们建立了改进的修正加权比特翻转(IMWBF)译码和最小和译码之间的自然关系。这有助于我们开发一种快速加权比特翻转(FWBF)解码算法。对于有限几何低密度奇偶校验码的译码,我们通过实例证明了FWBF译码可以在收敛性和性能上进一步改进IMWBF译码

Fast Weighted Bit-Flipping Decoding of Finite-Geometry LDPC Codes
In this letter, we establish a natural relationship between the improved modified-weighted-bit-flipping (IMWBF) decoding and min-sum decoding. This insight helps us to develop a fast weighted bit-flipping (FWBF) decoding algorithm. For decoding of finite-geometry low-density parity-check codes, we demonstrate through examples that the FWBF decoding can provide a further improvement to the IMWBF decoding on both convergence and performance
