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

这项小型企业技术转让（STTR）第二阶段项目的目标是实现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，并进行公共安全通信的试点试验。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有几个重要的作用，包括：(a)提高频谱效率，以纾缓无线频谱的紧张；(b)在紧急情况下为第一响应者提供优先的、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，提出了统计估计和决策算法，用于物理/介质访问控制（PHY/MAC）、网络和应用层的测量驱动的实时频谱管理。采用敏捷的软件栈实现和硬件集成，将基于这些思想演示一个完整的DSM系统。该项目的更广泛影响/商业潜力将是更好地了解与DSM相关的应用、监管政策和实际移动无线网络中的技术挑战。预计还会对最先进的弹性和可互操作的公共安全通信技术产生影响，特别是在紧急情况下。试点试验的结果将有助于形成减缓干扰、频谱共享、移动数据卸载和支持可靠的移动多媒体应用方面的知识体系。总的来说，这些市场为帝斯曼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.
