提出了一种基于信道信息校正的低密度奇偶校验（LDPC）码置信传播（BP）译码器。我们表明，我们的算法实现了相当大的性能增益（在瀑布和错误地板区域）相比，标准的BP解码器。通过实例验证，该译码器几乎达到了短LDPC码的最大似然译码性能
We propose an improved belief-propagation (BP) decoder for low-density parity-check (LDPC) codes based on channel information correction. We show that our algorithm achieves sizeable performance gains (in waterfall and error floor regions) compared to the standard BP decoder. We verify by examples that the proposed decoder almost achieves the maximum-likelihood decoding performance for short LDPC codes
