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

这个小型企业技术转移(STTR)第二阶段项目的目标是一个实用的动态频谱管理(DSM)架构和相应的一套创新的多层算法，开发一个支持DSM的多无线电路由器，并为公共安全通信进行试点试验。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。需求侧管理扮演着几个重要的角色，包括：(A)提高频谱效率以缓解无线频谱紧张；(B)在紧急情况下为急救人员提供优先、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。在本项目中，针对测量驱动的实时频谱管理，在物理/媒体接入控制(PHY/MAC)、网络和应用层提出了统计估计和决策算法。基于这些思想，将使用灵活的软件堆栈实现和硬件集成来演示一个完全工作的DSM系统。这个项目的更广泛的影响/商业潜力将是更好地了解与DSM相关的应用、监管政策和现实生活中移动无线网络的技术挑战。预计还将对最先进的具有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在干扰缓解、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。这些市场加在一起，构成了DSM技术价值数十亿美元的机会。

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.
