本文提出了一种基于云的同步链路混合射频光网络CHRONOS。该项目的主要目标是设计、构建和维护一个多节点、异构、宽带、可扩展、混合和同步的云无线接入网（Cloud RAN或C-RAN），专门用于支持需要太赫兹光和传统sub-6GHz技术（如Wi-Fi和蜂窝网络）的新兴应用。该试验台的新颖之处在于，通过集成同步射频和光链路，在多个方向上增强了C-RAN的核心能力，而这在当前的C-RAN部署中是不被考虑的。该项目的长期目标是利用测试平台进行无线和光通信的实际研究，重点是信号处理的新硬件和软件架构。在本文中，我们介绍了CHRONOS在室内环境中的设计、实现和初步结果，并为可扩展和实时网络提供了清晰的路径。我们的研究结果显示，在每个RF和光路中使用20MHz OFDM波形实现了跨多个边缘节点的同步接收，同时实现了108Mbps的总带宽。
This paper presents CHRONOS, a Cloud based Hybrid RF-Optical Network Over Synchronous Links. The primary goal of this project is to design, build and maintain a multi-node, heterogeneous, wideband, scalable, hybrid and synchronous Cloud Radio Access Network (Cloud RAN or C-RAN), specifically to support emerging applications requiring both THz-optical and conventional sub-6GHz technologies like Wi-Fi and cellular networks. The novelty of the testbed is in enhancing the core capabilities of C-RAN in multiple directions by integrating synchronous RF and Optical links that is not considered for contemporary C-RAN deployments. The long term goal of this project is to utilize the testbed to enable practical research in wireless and optical communication with emphasis on new hardware and software architecture for signal processing. In this paper, we present the design, implementation and initial results of CHRONOS, in an indoor setting, with a clear path to a scalable and real-time network. Our results show synchronous reception across multiple edge nodes while achieving an aggregate bandwidth of 108Mbps using 20MHz OFDM waveform in each RF and optical paths.
