STTR Phase II: SpiderRadio: Enabling Cognitive Dynamic Spectrum Access Wireless Communications

该小型企业技术转让（STTR）第二阶段项目的目标是实用的动态频谱管理（DSM）架构和相应的创新多层算法套件，开发支持DSM的多无线电路由器和公共安全通信试点试验。 动态频谱管理和接入是无线通信研究人员、频谱监管机构和国际标准化机构感兴趣的两个重要领域。DSM扮演着几个重要角色，包括：（a）提高频谱效率以缓解无线频谱紧缩;（B）在紧急情况期间为第一响应者提供优先级的、可互操作的通信;以及（c）降低无线接入的成本，以及（d）提高无线通信的可靠性和安全性。在这个项目中，统计估计和决策算法提出了测量驱动的实时频谱管理在物理/介质访问控制（PHY/MAC），网络和应用层。使用敏捷的软件栈实现和硬件集成，一个完整的工作DSM系统将证明基于这些想法。该项目更广泛的影响/商业潜力将是更好地理解DSM相关应用、监管政策和现实生活中移动的无线网络的技术挑战。预计还将对最先进的技术产生影响，以实现弹性和可互操作的公共安全通信，特别是在紧急情况下。试点试验的结果将有助于减少干扰、频谱共享、移动的数据卸载和支持可靠的移动的多媒体应用方面的知识体系。总的来说，这些市场为DSM技术提供了数十亿美元的机会。

This Small Business Technology Transfer (STTR) Phase II project targets a practical dynamic spectrum management (DSM) architecture and a corresponding suite of innovative multi-layer algorithms, development of a DSM enabled multi-radio router and pilot trials for public safety communications. Dynamic spectrum management and access are two important areas of interest to wireless communications researchers, spectrum regulators, and international standardization bodies. DSM plays several important roles, including: (a) improving spectrum efficiency to alleviate the wireless spectrum crunch; (b) providing prioritized, inter-operable communications for first responders during emergencies; and (c) reducing cost for wireless access, and (d) improving the reliability and security of wireless communications. In this project, statistical estimation and decision algorithms are proposed for measurement driven real-time spectrum management at the physical/medium access control (PHY/MAC), network and application layers. Using agile software stack implementation and hardware integration a completely working DSM system will be demonstrated based on these ideas. The broader impact/commercial potential of this project will be a better understanding of DSM related applications, regulatory policies and technical challenges in real-life mobile wireless networks. Impact on state-of-the-art technologies for resilient and interoperable public safety communications, especially during emergencies, is also expected. Findings from the pilot trials will contribute to the body of knowledge in interference mitigation, spectrum sharing, mobile data offloading and supporting reliable mobile multimedia applications. Taken together, these markets constitute a multi-billion dollar opportunity for DSM technologies.
