宽带相干PON与5G毫米波的灵活双工融合接入研究

在5G、云计算、多媒体服务等快速发展推动下，用户接入网的传输容量急速增加，迫切要求开发出能够承载多种业务、满足多种应用场景的新一代接入技术。目前针对相干PON的研究主要集中在下行传输研究，没有考虑灵活速率接入需求，突发上行传输研究也少有涉及。5G毫米波使用更高的频率，实现更快的速率，受到业界的广泛关注和重视。但是，5G毫米波频段高、传播损耗高、绕射和衍射能力弱，覆盖相对受限，这是5G毫米波通信系统面临的最大挑战。实现5G毫米波的高效、经济、高质量的深度覆盖成为当前最关注的问题之一。本项目旨在解决宽带相干PON与5G毫米波的灵活双工融合接入，研究灵活速率、低复杂度的相干PON下行传输；研究高效、稳定的宽带相干PON突发上行传输；研究基于大规模MIMO阵列天线的5G毫米波与光纤接入融合。旨在为新一代宽带光纤接入和5G毫米波融合提供解决方案，为推动我国5G毫米波未来两三年落地应用提供技术支撑。

Driven by the rapid development of 5G, cloud computing, and multimedia services, the transmission capacity of user access networks has rapidly increased, and there is an urgent need to develop a new generation of access technologies that can carry multiple services and meet multiple application scenarios. At present, the research on coherent PON mainly focuses on the research of downlink transmission, without considering the demand for flexible rate access, and the research of burst uplink transmission is rarely involved. 5G Millimeter-waves (mmW) use higher frequencies and achieve faster speeds, and have received extensive attention and attention from the industry. However, the 5G mmW frequency band is high, the propagation loss is high, the diffraction and diffraction capabilities are weak, and the coverage is relatively limited. This is the biggest challenge facing the 5G mmW communication system. Realizing the efficient, economical, and high-quality deep coverage of 5G mmW has become one of the most concerned issues at present. This project aims to solve the flexible duplex access of broadband coherent PON and 5G mmW, research on flexible rate, low-complexity coherent PON downstream transmission; research on efficient and stable broadband coherent PON burst upstream transmission; research on the integration of 5G mmW and optical fiber access based on massive MIMO array antenna. It aims to provide a solution for the new generation of broadband optical fiber access and 5G mmW integration, and to provide technical support for the promotion of our country's 5G mmW application in the next few years.
