AI中文摘要：
广义积码（GPC）兼具出色的高速率性能和低复杂度硬件实现。我们提出了改进的动态可靠性分数译码器（\acs{RDRSD}），这是一种使用动态可靠性分数的硬消息传递迭代误码和擦除译码器。其伴随式域实现的复杂度与硬判决\ac{iBDD}相当。在各种GPC和译码配置中，\acs{RDRSD}提供了不同的复杂度-性能权衡，比\ac{iBDD}实现了约1dB的编码增益。对于具有小纠错能力分量码的GPC，我们还分析了误码平底并提出了显著降低它的软辅助后处理步骤。
英文摘要：
Generalized product codes (GPCs) combine excellent high-rate performance with low-complexity hardware implementations. We propose the refined dynamic reliability score decoder (\acs{RDRSD}), a hard-message-passing iterative error-and-erasure decoder that uses dynamic reliability scores. Its syndrome-domain implementation has complexity comparable to hard-decision \ac{iBDD}. Across various GPCs and decoding configurations, \acs{RDRSD} provides different complexity--performance trade-offs and achieves approximately \SI{1}{dB} coding gain over \ac{iBDD}. For GPCs with component codes of small error-correcting capability, we also analyze the error floor and propose a soft-aided post-processing step that significantly lowers it.
