SBIR Phase I: Efficient Testing Methodologies for Adaptive Radios

这个小型企业创新研究(SBIR)第一阶段项目将进行研究，以开发新的行为表征方法，使自适应/认知无线电能够迅速推向市场，提高频谱利用率，从而为所有人提供宽带接入。预期结果包括由高效自适应搜索算法控制的闭环测试夹具设计，该设计可根据实验室环境中测量的自适应系统行为动态创建逼真的射频环境。模拟真实的动态射频环境所涉及的复杂性足以描述自适应系统的行为，这使得测试用例的数量增加到数亿，测试时间达到数年。自适应搜索问题将使用全局优化的实验替代方案和多维分裂级别来解决，从而产生高置信度结果和合理的测试时间。该项目将把这种高效的搜索自适应、罕见事件方法与该公司独特的动态射频环境仿真能力相结合，以创建支持全面硬件在环测试的虚拟射频环境。拟议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，从而产生更好的频谱接入。该项目更广泛的影响/商业潜力是加速自适应/认知无线电的部署，为国家服务不足的人提供无所不在的宽带接入的前景。缺乏对日常生活日益重要的普遍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，以利用现有频谱满足这些日益增长的需求，但承认缺乏强大的测试能力，以确保与现有系统无干扰共存。部署自适应无线电技术的挑战是，如果没有全面的测试，它就无法现场部署，而且由于担心干扰现有频谱用户，无法在现场、人口稠密的射频系统环境中进行测试。该项目将开发一种系统，在实验室中以现场级别的保真度有效地验证自适应无线电。高效、高质量的测试提供了以显著降低的成本实现更快部署的潜力。自适应/认知无线电的潜在用途包括商业固定和移动无线、特别网络、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未得到充分服务的个人受益，并加强对应用于自适应/认知无线电的自适应、罕见事件搜索技术的科学和技术了解。

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.
