摘要
随着5G通信技术的发展,多样化的应用场景对光纤通信系统的接入灵活性提出了更高的要求.概率整形是一种具有低复杂度、高灵活度的新型调制编码技术.目前,该技术已经在国内外掀起了研究的热潮,引起众多科研工作者的关注.概率整形不仅可实现灵活的宽带光接入,而且可以对超大星座尺度的正交幅度调制信号进行优化.本文介绍了笔者所在团队在概率整形方面的一系列研究成果并展开讨论,希望能为未来光纤通信系统的研究提供借鉴与依据.
With the development of 5G communication technology and its diverse application scenarios,the requirements for access flexibility in optical fiber communication systems have increased.Probabilistic shaping is a new modulation and coding technology with lower complexity and higher flexibility.Currently,this technology has mobilized research across the world and attracted the attention of many researchers.Probabilistic shaping not only enables flexible broadband optical access,but also optimizes quadrature amplitude modulation signals at the scale of large constellations.In this study,we will discuss a series of research achievements by our team in the field of probabilistic shaping,and hope to provide guidance and references for future optical fiber communication systems.
