摘要:

提出了一种新的低密度奇偶校验(LDPC)码的比特翻转(BF)译码算法。所提出的算法称为梯度下降比特翻转(GDBF)算法,可以看作是简化的梯度下降算法。基于梯度下降公式,所提出的算法是自然地从一个简单的非线性目标函数。

英文摘要:

A novel class of bit-flipping (BF) algorithms for decoding low-density parity-check (LDPC) codes is presented. The proposed algorithms, which are called gradient descent bit flipping (GDBF) algorithms, can be regarded as simplified gradient descent algorithms. Based on gradient descent formulation, the proposed algorithms are naturally derived from a simple non-linear objective function.
