摘　　要：随着通信技术的不断进步,LDPC码以其优越的纠错性能和高效译码算法成为信道编码中关键技术之一,被广泛应用于多种通信标准中。其中,多元LDPC码在高阶调制下以及突发错误信道中表现更好,尤其是短到中等码长条件下性能提升明显,但也存在不足。为了更好协调频带利用率与误码率之间关系,降低译码复杂度,文章对多元LDPC码的构造与译码方面展开论述,主要阐述了其发展历程和研究现状,探讨了目前存在的问题以及改进方向。With the continuous progress of communication technology,LDPC codes with superior error correction performance and efficient decoding algorithm have become one of the key technologies in channel coding,which are widely used in a variety of communication standards.Among them,non-binary LDPC codes perform better in high-order modulation or burst error channel,especially under the condition of short to medium code length.In order to obtain better error correction performance and coordinate the relationship between spectral efficiency and bit error rate,this paper discusses the construction and decoding of non-binary LDPC codes,mainly expounds the development history and research status,and discusses the existing problems and improvement directions.
