这项小企业创新研究（SBIR）第一阶段项目将研究开发新的行为表征方法，使自适应/认知无线电能够迅速引入市场，提高频谱利用率，从而实现所有人的宽带接入。预期的结果包括一个闭环测试夹具设计，它可以动态地创建真实的射频环境，以响应实验室环境中测量的自适应系统行为，由一个有效的自适应搜索算法控制。模拟真实动态射频环境的复杂性足以表征自适应系统的行为，这使得测试用例的数量达到数亿，测试时间长达数年。自适应搜索问题将使用全局优化的实验方案和多维分裂水平来解决，从而产生高置信度的结果和合理的测试时间。该项目将这种高效的搜索自适应、罕见事件方法与公司独特的动态射频环境仿真能力相结合，创建支持全面硬件在环测试的虚拟射频环境。所提出的研究的智力价值在于结合和改进自适应/认知无线电测试关键应用领域的这些独特能力，从而改进频谱接入。该项目的更广泛的影响/商业潜力是加速自适应/认知无线电的部署，为全国服务不足的地区提供无处不在的宽带接入前景。缺乏对日常生活日益重要的通用宽带接入正在损害美国。2012年PCAST报告建议使用自适应/认知无线电作为解决方案，以满足现有频谱日益增长的需求，但承认缺乏强大的测试能力，以确保与现有系统的无干扰共存。部署自适应无线电技术的挑战在于，如果没有全面的测试，它就无法投入使用，而且由于担心干扰现有频谱用户，也无法在现场、人口密集的射频系统环境中进行测试。该项目将开发一个系统，在实验室中有效地验证具有现场保真度的自适应无线电。高效、高质量的测试以显著降低的成本提供了更快部署的潜力。自适应/认知无线电的潜在用途包括商业固定和移动无线、自组织网络、卫星、航空、国防部、英特尔和公共安全，潜在收入达数亿美元。该项目可能使数百万服务不足的个人受益，并增强对应用于自适应/认知无线电的自适应、罕见事件搜索技术的科学和技术理解。

This Small Business Innovation Research (SBIR) Phase I project will perform research toward developing new behavior characterization methodologies that allow adaptive/cognitive radios to be rapidly introduced into the market improving spectrum utilization and therefore broadband access for all. Expected results include a closed loop test fixture design that dynamically creates realistic RF environments in response to measured adaptive system behavior in a laboratory setting, controlled by an efficient adaptive search algorithm. The complexities involved in simulating realistic dynamic RF environments, sufficient to characterize the behavior of adaptive systems, drive the number of testing cases into the hundreds of millions and test time to many years. The adaptive search problem will be solved using globally optimized experimental alternatives and multi-dimensional splitting levels yielding high confidence results and reasonable test times. The project will combine this efficient search adaptive, rare-event approach with the company's unique dynamic RF environment emulation capabilities to create virtual RF environments that support comprehensive hardware-in-the-loop testing. The intellectual merit of the proposed research lies in combining and improving these unique capabilities in the critical application area of adaptive/cognitive radio testing yielding improved spectrum access.The broader impact/commercial potential of this project is acceleration of the deployment of adaptive/cognitive radios, offering the prospect of ubiquitous broadband access to the nation's underserved. Lack of universal broadband access, increasingly essential to daily life, is hurting the U.S. The 2012 PCAST report recommends using adaptive/cognitive radio as a solution to meeting these increased demands with existing spectrum, but acknowledges the lack of robust testing capabilities to ensure non-interfering coexistence with incumbent systems. The challenge of deploying adaptive radio technology is that it cannot be fielded without comprehensive testing, and cannot be tested in a live, densely populated RF system environment for fear of interfering with existing spectrum users. This project will develop a system to efficiently validate adaptive radios in the laboratory with field level fidelity. Efficient, high quality testing offers the potential for quicker deployments at significantly reduced costs. The potential uses for adaptive/cognitive radios include commercial fixed and mobile wireless, ad-hoc network, satellite, aviation, DoD, Intel and public safety with potential revenues of hundreds of millions of dollars. This project may benefit millions of underserved individuals and enhance scientific and technological understanding of adaptive, rare-event search techniques as applied to adaptive/cognitive radios.
