摘　　要：为了满足当前日益增长的带宽需求,下一代接入网络将支持单波长50 Gb/s及以上的传输速率,同时确保以经济高效的方式与传统网络共存。基于数字信号处理的先进的调制和检测技术是实现该目标的有力支撑,能为大规模接入和多场景多业务承载提供很好的支持。描述了几种新型多载波调制技术的产生原理和主要特点,总结了其在无源光网络(PON)中的研究现状和存在的问题,并结合下一代PON的诉求提出了研究方向建议。In order to meet the increasing bandwidth requirements,the next generation access network is required to support each wavelength transmission speed exceeding 50 Gb/s,while ensuring the coexistence of traditional network in an economical and efficient manner.Advanced modulation and detection technologies based on digital signal processing is a powerful support to achieve this goal,which can provide good support for large-scale,multi-scene and multi-service access.The principle and main characteristics of several new multi-carrier modulation technologies are discussed in this paper,and their research status and existing problems in passive optical network(PON)are reviewed.What's more,the suggestions on research direction based on the appeal of the next generation PON are put forward.
