摘要

流式通信是光纤通信网络和移动通信网络中重要的通信场景，区别于传统的间歇式或分块通信场景，流式通信中传输的数据具有典型的连续流式特性.面向流式通信场景，耦合码因其相对于传统分组码具有显著的性能提升，加之其天然的低编译码时延结构，成为流式通信场景中重要的信道编码候选技术.本文先回顾现有的耦合低密度校验（Low-Density Parity-Check，LDPC）码技术，包括：乘积类耦合LDPC码、部分重编码类耦合LDPC码、空间耦合LDPC码和全局耦合LDPC码.在此基础上，本文进一步介绍了基于便车码技术的耦合LDPC码改进提升设计，并介绍了基于分组马尔可夫叠加传输技术的一类新型耦合LDPC码.最后，本文对耦合LDPC码的发展前景和研究方向进行展望.

Abstract

Streaming communication is an essential communication scenario in optical fiber communication networks and mobile communication networks. Unlike traditional intermittent or block-oriented communication

the data transmission in streaming communication exhibits typical continuous streaming characteristics. Coupled codes

compared to traditional block codes

have shown significant performance improvement in streaming communication scenarios. Additionally

they inherit low encoding and decoding latency. These advantages make coupled codes an important candidate for channel coding in streaming communication scenarios. This paper first reviews existing coupled LDPC codes

including product-like coupled LDPC codes

partially reencoded coupled LDPC codes

spatially coupled LDPC (SC-LDPC) codes

and globally coupled LDPC (GC-LDPC) codes. Following that

this paper introduces a series of improved designs for coupled LDPC codes based on free-ride codes

and introduces a new class of coupled LDPC codes based on block Markov superposition transmission (BMST) techniques. Finally

this paper concludes with a discussion on future prospects and research directions of the coupled LDPC codes.
