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 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. It is projected that the cost per 80 MHz link with the active interference cancellation system for the wireless backhaul application will be approximately $2,000. At this cost value, the technology can be implemented into a variety of commercial applications including video surveillance, smart grid, and mobile data.This Small Business Innovation Research (SBIR) Phase I project provides a unique solution to the challenging interference problem in many wireless networks. This problem is particularly troublesome in the emergent market of the unlicensed 5GHz range for wireless backhaul systems. Unlike conventional radio frequency (RF) and digital interference mitigation or cancelation techniques, the proposed interference cancellation system (ICS) generates unmatched levels of cancellation by using analog signal processing with electro-optic components. The ICS is the key approach that can enable high quality of service in backhaul networks. Taking advantage of the already developed prototype, the proposed system configuration will be demonstrated with representative signal types and components. In addition, as an alternative to the off-the-shelf mechanical delay line, an interferometric based delay line will be investigated for faster tuning speed. Based on the investigations, the product design for backhaul application will be analyzed for commercialization. The anticipated key performance parameters of the product could provide maximum of 80 dB of cancellation over narrowband (10kHz) and 40 dB over broadband (80MHz) for co-site interference.

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经济实惠的技术解决方案，以满足持续爆炸性的社会/客户对数据访问的需求。 该项目的预期技术和商业成果是主动干扰抑制能力，其产品特点包括显着提高服务质量、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体成本，并减少系统的尺寸、重量和功率要求。预计无线回程应用中采用有源干扰消除系统的每条 80 MHz 链路的成本约为 2,000 美元。以此成本价值，该技术可以实施到各种商业应用中，包括视频监控、智能电网和移动数据。这个小型企业创新研究 (SBIR) 第一阶段项目为许多无线领域具有挑战性的干扰问题提供了独特的解决方案。网络。这个问题在无线回程系统的免许可 5GHz 范围的新兴市场中尤其麻烦。与传统的射频（RF）和数字干扰减轻或消除技术不同，所提出的干扰消除系统（ICS）通过使用带有电光组件的模拟信号处理来产生无与伦比的消除水平。 ICS 是在回程网络中实现高质量服务的关键方法。利用已开发的原型，将通过代表性信号类型和组件来演示所提议的系统配置。此外，作为现成机械延迟线的替代方案，将研究基于干涉测量的延迟线以实现更快的调谐速度。根据调查结果，将对回程应用的产品设计进行商业化分析。该产品的预期关键性能参数可在窄带 (10kHz) 上提供最大 80 dB 的共址干扰消除，在宽带 (80MHz) 上提供最大 40 dB 的共址干扰消除。
