摘　　要：作为一种针对调制格式的优化技术,星座整形技术极大提高了传统编码调制方案的灵活性、非线性补偿和误码性能,具有能够在不增加系统发送功率、复杂性的前提下,获得高频谱效率和实现接近香农极限的信号传输等特性,在多个领域得到广泛的应用。本文介绍了国内外星座整形技术方案的研究现状和最新进展,特别是基于概率整形技术实现类型、方法、架构等层面,从多个角度着重分析了算术编码概率整形的基本原理、性能对比和相关应用,在不同的系统和场景下对比评估概率整形技术带来的增益,并总结了光通信中概率整形技术目前面临的问题及未来的发展趋势。As one optimization technique for modulation format,constellation shaping technique greatly improves the flexibility,nonlinear compensation and error performance of traditional coding modulation scheme.It can achieve high spectral efficiency and signal transmission close to Shannon’s limit without increasing the transmission power and complexity of the system,which has been widely used in many fields.The research status and the latest advances in the fields of constellation shaping technology schemes are introduced,especially the type,method,architecture and other aspects.The basic principle,performance comparison and related applications of probabilistic shaping with arithmetic coding are mainly discussed and the current problems and future trends of probabilistic shaping techniques are summarized.
