中文摘要： 动态自适应光接入系统可能够根据业务需求实现弹性的资源调度与灵活的比特流分配，是未来光接入网的热点研究领域，全网动态资源调度和自适应比特分配是其关键问题。动态的资源管控需要协同考虑载波、比特流、星座分布等多个参量的优化控制；光分配网需要在保持无源特性下实现频谱动态配置；接入系统频繁的业务切换和用户交互需要自适应分配与识别机制来实现物理层的数据流分配，缓解上层压力。 本申请将基于可编程多参量管控机制，研究动态自适应光接入系统模型，综合分析多参量的调度协同，实现资源优化匹配；提出能量与信息共传的光纤分配节点构造方法，包括信号的低噪损耗补偿与动态分配的机理；研究基于星座排布和聚类分析的自适应比特分配与识别方法，搭建动态自适应光接入实验系统。研究成果可为发展下一代动态、智能的光纤接入网提供参考，具有一定理论意义与实用价值。

英文摘要： The dynamic adaptive optical access system can realize flexible resource assignment and bit stream allocation according to the service requirement, which becomes a hot research area in future optical access network. The dynamic resource assignment and adaptive bit allocation are the key issues. The dynamic resource management needs to consider the jointly optimal control of carriers, bit stream, constellation mapping and so on; the optical distribution network needs to realize the spectrum allocation based on passive structure; the frequent service changing and user interaction need adaptive allocation and recognize mechanism to realize data stream assignment at physical layer and relieve the pressure on high-layers. Bases on the programmable multi-parametric control mechanism, this application will research the model of dynamic adaptive optical access system, analyze the collaborative scheduling among these parameters and realize the resource optimization matching; we will propose the method of optical distribution node with energy and data synchronized transmission, including the low noise compensation of signal loss and mechanism of dynamic allocation; we will also study the method of adaptive bit allocation and reorganization based on constellation mapping and cluster analysis, and build the experiment of dynamic adaptive optical access system. The research results have theoretical and practical significance for the development of next generation dynamic and intelligent fiber access network.
