This Small Business Technology Transfer (STTR) Phase I project consists of the research and development of a comprehensive, integrated multi-layer solution for cognition enabled dynamic spectrum access wireless communications. Several spectrum measurement studies indicate that valuable radio spectrum is severely underutilized. This has resulted in time and geographical region specific spectrum holes or white spaces. The intellectual merits of this project consists of the following technical objectives: (a) development of sensing algorithms to identify unused or underused spectrum in real-time by optimally trade-off sensing accuracy for delay; (b) design of a medium access control protocol that will enable dynamic spectrum access based on the information provided by the sensing algorithms; (c) development of a multi-network communication protocol to enhance spectrum access; and (d) cross-layer optimization of these protocols to significantly improve the data rate while achieving the application delay constraints. The broader impact/commercial potential of this project will be in the understanding of practically achievable performance of cognitive dynamic spectrum access wireless networks. Highly accurate models and simulation tools for designing cognitive wireless networks will be developed. These will be very valuable to the technical and practitioner communities. The proposed technology will lead to interoperable wireless public safety communications, low cost rural broadband connectivity in television white spaces, and infrastructure for robust mobile video applications. The combined market size for these sectors is estimated to be several billion dollars, globally.

该小型企业技术转让 (STTR) 第一阶段项目包括研究和开发全面的集成多层解决方案，用于支持认知的动态频谱接入无线通信。多项频谱测量研究表明，宝贵的无线电频谱严重未得到充分利用。这导致了时间和地理区域特定的频谱漏洞或空白。该项目的智力优点包括以下技术目标： (a) 开发传感算法，通过最佳权衡传感精度和延迟来实时识别未使用或未充分利用的频谱； (b) 设计一种介质访问控制协议，该协议将实现基于传感算法提供的信息的动态频谱访问； (c) 开发多网络通信协议以增强频谱接入； (d) 这些协议的跨层优化，以显着提高数据速率，同时实现应用延迟约束。该项目更广泛的影响/商业潜力将在于了解认知动态频谱接入无线网络的实际可实现性能。将开发用于设计认知无线网络的高精度模型和仿真工具。这些对于技术和从业者社区来说非常有价值。拟议的技术将带来可互操作的无线公共安全通信、电视空白区的低成本农村宽带连接以及强大的移动视频应用的基础设施。全球这些行业的市场总规模估计达数十亿美元。
