【摘要】：摘要：随着以移动视频为代表的宽带业务的飞速发展；以大数据处理、物联网和云计算为代表的新技术概念的迅猛兴起,使得通信网的传输带宽日益紧张。当前,已经部署的10、40Gbps传输网络已经不能满足来自不同领域新型技术与应用的带宽要求,各大运营商都将目光聚集在100Gbps超高速网络建设上,所以本文的研究内容具有重大意义。 《通信工程专业教学改革与研究》是北京交通大学承担的国家级教改项目。该项目瞄准建设“一流研究型”大学的发展目标,优化通信专业结构,提升水平,创新人才培养模式,为培养出国家所需的优秀通信人才而努力。为了满足国家级通信工程特色专业实验教学平台的建设要求,针对“2013年是中国100Gbps高速光传输系统商用元年”这一状况,我校去年开始进行光通信与光器件实验平台建设,基于该实验平台可以进行与高速光传输系统相关的研究和实验。本文围绕我校通信工程国家级教改项目中的“光通信与光器件实验平台建设”进行工作,主要的创新点和研究工作包括： 1.在本文中对100Gbps光通信系统的传输过程进行了详细的理论分析,然后用OptiSystem和Matlab软件建模了120Gbps DP-QPSK相干光传输系统,给出了建模仿真结果图。在此基础上,提出了我专业实验室搭建该系统的解决方案,该方案完全符合实验室设备采购原则：通过利用实验室现有仪器,在满足系统性能条件下搭建该系统,并尽可能节约采购成本。 2.针对现代通信系统中全数字化、全智能化这一趋势特点,本文提出了一种基于改进粒子群算法的载波相位估计K-PSO算法,并用Matlab软件对它进行仿真,从不同角度进行了详细分析。K-PSO算法具有智能化高、控制参数少、扩展性强等优点。在展望中,又提出一种K-PSO与基于网格密度的聚类相结合的载波相位估计算法。在我校光通信与光器件实验平台搭建完成后,可以进行背靠背实验验证,本文对新算法的提出也是对该实验平台未来应用效果的预期。
[Abstract]:Absrtact: with the rapid development of broadband services represented by mobile video, the rapid rise of new technological concepts represented by big data processing, Internet of things and cloud computing makes the transmission bandwidth of communication networks increasingly tight. At present, the deployed 10 Gbps transmission network can no longer meet the bandwidth requirements of new technologies and applications from different fields, and the major operators will focus on the construction of 100Gbps ultra-high speed network, so the research content of this paper is of great significance. Teaching Reform and Research of Communication Engineering is a national teaching reform project undertaken by Beijing Jiaotong University. The project aims at the development goal of building "first-class research" university, optimizes the structure of communication specialty, improves the level, innovates the talent training mode, and strives to train the excellent communication talents needed by the country. In order to meet the construction requirements of the national experimental teaching platform for characteristic specialty of communication engineering, in view of the situation that "2013 is the commercial year of 100Gbps high-speed optical transmission system in China", our school began to carry out the construction of optical communication and optical device experimental platform last year. Based on this experimental platform, the research and experiment related to high-speed optical transmission system can be carried out. This paper focuses on the construction of optical communication and optical device experimental platform in the national educational reform project of communication engineering in our university. The main innovations and research work include: 1. In this paper, the transmission process of 100Gbpsoptical communication system is analyzed in detail, and then the 120Gbps DP-QPSK coherent optical transmission system is modeled with OptiSystem and Matlab software, and the modeling and simulation results are given. On this basis, the solution of building the system in our professional laboratory is put forward, which fully accords with the purchasing principle of laboratory equipment: by using the existing instruments in the laboratory, the system is built under the condition of satisfying the performance of the system, and the purchase cost is saved as much as possible. two銆，
