在本封信中，我们提出了SHINE，一种基于符号的启发式迭代NB-LDPC编码MIMO BP检测与译码方案。更具体地说，我们开发了一种配备了针对实域检测与Galois域译码之间定制化对数似然比（LLR）接口的NB-LDPC编码迭代检测与译码（IDD）接收机。为进一步降低IDD接收机的复杂度，我们提出了联合符号剪枝优化（JSPO）框架，利用元启发式学习联合优化检测与译码中的符号搜索空间。数值结果表明，与基本版本相比，SHINE在保证性能不下降的前提下，成功实现了检测和译码复杂度分别降低高达37.32%和58.31%。数值结果也展示了所提出的SHINE与其他NB-LDPC编码IDD方案的对比性能优势。
