SBIR Phase II: Interference Mitigation for Broadband Wireless Backhaul Systems

该项目更广泛的影响/商业潜力是使无线行业运营商和设备提供商能够提供负担得起的技术解决方案，以满足持续爆炸性的社会/客户数据访问需求。电信市场部门日益向亚洲和欧洲整合，外国政府正在进行战略投资，以鼓励在各自国家开展工作。从长远来看，所提出的干扰消除技术可以增加美国电信设备部门的投资，并有效利用有限的射频（RF）频谱。 该项目的预期技术和商业成果是具有主动干扰缓解能力的产品功能，包括显著提高服务质量，简化网络设备设计和安装，以及降低对天线和滤波器等许多组件的要求。这反过来将降低每个数据链路的总成本，以及降低系统的尺寸、重量和功率要求。这个小型企业创新研究（SBIR）第2阶段项目解决了对破坏性射频干扰缓解解决方案的迫切需求。随着网络朝着更高性能的方向发展，以适应前所未有的更大容量，网络运营商、行业组织和设备提供商正在研究下一代5G无线网络的创新技术。 所提出的干扰消除技术具有两个优点。一个优点是极宽的瞬时带宽，另一个是灵活的可调谐性超过GHz的工作频率。 这些优势有助于整合和减少前端硬件。该计划的重点将首先放在开发具有单片光子集成电路的干扰消除系统的光学系统芯片版本上。凭借功能齐全的开发板，第二个重点将是展示无线回程网络带内干扰抑制应用，并展示2倍频谱效率的改进和1000倍容量的潜在增长。

The broader impact/commercial potential of this project is to enable wireless industry carriers and equipment providers with an affordable technology solution to meet the continuing explosive societal/customer demands for data access. The telecommunication market sector has been increasingly consolidating to Asia and Europe where foreign governments are making strategic investments to encourage work in their respective countries. In a long-term, the proposed interference elimination technology can lead to increased investment in the telecom equipment sector and efficient use of the finite radio frequency (RF) spectrum in the United States. The expected technical and commercial outcome from the project is an active interference mitigation capability with product features including a significantly improved quality of service, simplified network equipment design and installation, and reduced requirements for many components such as antenna and filters. This in turn will reduce the overall cost per data link, as well as reducing the size, weight, and power requirements of the system. This Small Business Innovation Research (SBIR) Phase 2 project addresses the critical need for disruptive RF interference mitigation solutions. As networks are moving toward higher performance to accommodate larger capacity than ever seen before, the network operators, industry organizations, and equipment providers are looking into innovative technologies for next generation 5G wireless networks. There are two advantages offered by the proposed interference elimination technology. One advantage is extreme wide instantaneous bandwidth and the other is flexible tunability over GHz of operating frequency. These advantages help to consolidate and reduce front-end hardware. The focus of this program will be first on developing an optical system-on-chip version of the interference cancellation system with monolithically photonic integrated circuits. With a complete and fully function development board, the second focus will be on demonstrating the application in in-band interference mitigation for wireless backhaul networks, and showing improvement in 2x spectral efficiency and potential 1000x increase in capacity.
