This project seeks an innovative approach to the design of very high-bandwidth and ubiquitous wireless networks exploiting the unique properties of RF-photonic signal processing and integrated photonics for emerging next-generation and high-bandwidth 5G technologies. The flexibility offered by the photonic and electronic system co-design has the potential to provide a 100-fold increase in bandwidth available for the mobile users, compared to what currently available with current technology. This project will exploit key enabling physical layer technologies, such as dynamic optical waveform generation and measurement (OAWG and OAWM) on silicon photonics (SiP), together with SiP lattice filters (SiPhaser) and photonic mixers. The combination of these technologies will provide a unique and efficient front-haul architecture to perform analog massive-MIMO beamforming at mm-wave frequencies without requiring any complex high-speed RF circuitry. The following topics will be investigated: (1) RF-Optical Networking architecture design and performance studies; (2) DSP, coding, and mmWave-MIMO algorithms development; (3) simulation studies of analog RF-optical beamforming by SiPhaser filters; (4) Proof-of-principle demonstration of SDM MIMO mmWave with RF-photonic processing.Future Internet applications will exponentially increase the demand for ubiquity, mobility, and bandwidth through diverse platforms, in particular, rapidly expanding cloud data center infrastructures. Today's wireless networks are typically limited to 1~100 Mb/s connectivity with limited end-to-end throughput, latency, and reliability. While fiber optic networks provide 1~100 Tb/s capacity on each single-mode-fiber over thousands of kilometer distances, they are limited to wide area and metro networks, not readily accessible by mobile users. This project seeks to improve our nation's cyberinfrastructure by making additional bandwidth available to citizens with mobile devices. The project will also provide an exciting opportunity to train students in design, developing, and testing algorithms and physical layer technologies on a futuristic networking platform.

该项目寻求一种创新的方法，用于设计非常高带宽和无处不在的无线网络，利用了RF-Photonic信号处理的独特属性以及用于新兴的下一代和高带宽5G技术的集成光子学的独特属性。与当前技术相比，光子和电子系统共同设计提供的灵活性有可能为移动用户提供100倍的带宽。该项目将利用启用物理层技术的密钥，例如在硅光子学上（SIP）上的动态光波形产生和测量（OAWG和OAWM），以及SIP晶格过滤器（Siphaser）和光子混合器。这些技术的组合将提供独特而有效的前豪尔结构，以在MM波频率下进行模拟巨大的MIMO光束，而无需任何复杂的高速RF电路。将研究以下主题：（1）RF光学网络体系结构设计和性能研究； （2）DSP，编码和MMWAVE-MIMO算法开发； （3）通过Siphaser滤波器对模拟RF光束进行模拟研究； （4）使用RF-Photonic处理的SDM MIMO MMWAVE的原则证明。FutureInternet应用程序将通过不同的平台，特别是迅速扩展云数据中心基础架构，将互联网应用程序成倍增加对无处不在，移动性和带宽的需求。当今的无线网络通常限制为1〜100 MB/s连接，端到端吞吐量，延迟和可靠性有限。虽然光纤网络在每千公里距离内提供1〜100 TB/S的容量，但它们仅限于广阔的区域和地铁网络，而移动用户不容易访问。该项目旨在通过为具有移动设备的公民提供额外的带宽来改善我们国家的网络基础设施。该项目还将为学生在未来派网络平台上培训学生进行设计，开发和测试算法和物理层技术的激动人心的机会。
