This proposal presents CHRONOS - 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 high throughput wireless access for emerging applications like Virtual Reality (VR), Industrial Internet of Things (IoT), 3D broadcast video, tele-surgery, etc. The combination of tight synchrony and heterogeneity among the network constituents make CHRONOS radically different and foundational to investigate previously unexplored research problems in wireless networking and communication. This infrastructure cuts across multiple domains including wireless networks, digital communication, signal processing, optical communication, hardware and software architectures and parallel processing. In addition to global technological and social impact, students at the state University at Albany will be trained using this testbed. The highly diversified student body in the university includes traditionally underrepresented communities, who will greatly benefit from hands-on workshops, seminars, summer programs and student interest groups hosted by the researchers throughout the duration of the project. The testbed will not only enable research at Albany, but will also foster long-term collaborations beyond the campus as well.CHRONOS enhances the capabilities of conventional C-RAN in multiple directions by integrating synchronous radio frequency and optical links. 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 architectures for signal processing. Specifically, this project will 1) develop baseband transceiver in multi-field-programmable gate array (FPGA)-based cloud platform, edge nodes as well as mobile terminals to enable high bandwidth communication, 2) interface between the cloud and the edge nodes to split edge-cloud processing, 3) partition between FPGA and graphical processing unit (GPU) co-processor for parallelism in baseband, and 4) enable dynamic reconfiguration for digital signal processing (DSP) modules as required by applications. The key architectural advantage of CHRONOS is the decoupling of baseband signal processing from the front end allowing for complex, joint processing of signals from spatially distributed radio units. It also optimizes real-time performance by having computation capabilities at the network edge while trading off energy consumption. Spatially distributed antenna geometry alleviates the inefficiencies imposed by co-located antennas in existing communication methods. It also advances the research in virtual cloud platforms that support partial reconfiguration of FPGA to scale the DSP tasks based on demand. These efforts in multiple fundamental domains are tightly coupled and require close interaction to realize the full potential of this infrastructure.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该提案介绍了计时 - 基于云的混合RF光学网络在同步链路上。 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 high throughput wireless access for emerging applications like Virtual Reality (VR), Industrial Internet of Things (IoT), 3D broadcast video, tele-surgery, etc. The combination of tight synchrony and heterogeneity among the network成分使计时截然不同且基础，以研究以前未开发的无线网络和通信研究问题。该基础架构跨越了多个领域，包括无线网络，数字通信，信号处理，光学通信，硬件和软件架构以及并行处理。除了全球技术和社会影响外，奥尔巴尼州立大学的学生还将使用此测试台接受培训。该大学的高度多样化的学生团体包括传统上代表性不足的社区，他们将在整个项目期间由研究人员主持的动手研讨会，研讨会，夏季计划和学生兴趣小组受益。测试床不仅可以在奥尔巴尼进行研究，而且还将促进校园之外的长期合作。Chronos通过整合同步射频和光学链接来增强常规C-RAN在多个方向上的能力。该项目的长期目标是利用测试床来实现无线和光学通信的实践研究，重点是用于信号处理的新硬件和软件架构。 Specifically, this project will 1) develop baseband transceiver in multi-field-programmable gate array (FPGA)-based cloud platform, edge nodes as well as mobile terminals to enable high bandwidth communication, 2) interface between the cloud and the edge nodes to split edge-cloud processing, 3) partition between FPGA and graphical processing unit (GPU) co-processor for parallelism in baseband, and 4) enable数字信号处理（DSP）模块的动态重新配置按应用程序要求。计时的关键架构优势是从前端将基带信号处理的解耦，从而使从空间分布的无线电单元进行复杂的联合处理。它还通过在交易能源消耗的同时在网络边缘具有计算功能来优化实时性能。空间分布的天线几何形状减轻了在现有的通信方法中共同位置的天线施加的效率低下。它还可以在虚拟云平台中进行研究，以支持FPGA部分重新配置，以根据需求扩展DSP任务。这些在多个基本领域的努力紧密耦合，需要密切的互动才能实现该基础设施的全部潜力。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估评估标准来通过评估来获得支持的。
