Minimization of energy consumption is critical to developing green, sustainable technologies for cognitive radio terminals that can connect to networks that operate on different frequency bands with a variety of air interfaces. The intellectual merit of this project is a unified and coherent consideration of RF components, communication system algorithms, baseband computation platforms, and design tools, to greatly increase spectrum sharing efficiency. Dataflow methodologies are a promising candidate for the modeling, analysis and verification of cognitive radio systems. As dataflow models are abstract and platform independent, the same model can be used to generate implementations for very different devices from low-power sensor nodes to high-end mobile terminals. The key novelty is in the development of systematic methods for design, implementation, and integration of configurable RF chains, and in the development of dataflow methods for formal analysis and optimization of these new capabilities. The expected results are: (1) Energy consumption models and a design framework for computation, control and configuration of future radio devices, leveraging the investigators' existing experimental testbeds, (2) Configurable radio architectures for wide-scale cognitive access of noncontiguous RF spectrum, and (3) Design methodologies for flexible, energy-efficient cognitive wireless networks. The broader impact includes international collaboration through the WiFiUS program creating a holistic design for configurable frequency agile terminals. A novel interdisciplinary approach is enabled by the unique international team, which builds upon collaborations between experts at the Tampere University of Technology and University of Oulu in Finland, and Rice University and the University of Maryland in the US.

最大限度地减少能源消耗对于开发认知无线电终端的绿色、可持续技术至关重要，这些终端可以通过各种空中接口连接到在不同频段上运行的网络。该项目的智力优势在于对射频组件、通信系统算法、基带计算平台和设计工具进行统一和连贯的考虑，从而大大提高频谱共享效率。数据流方法是认知无线电系统建模、分析和验证的有希望的候选者。由于数据流模型是抽象的且独立于平台的，因此可以使用相同的模型为从低功耗传感器节点到高端移动终端的非常不同的设备生成实现。关键的新颖之处在于开发用于设计、实现和集成可配置射频链的系统方法，以及开发用于形式分析和优化这些新功能的数据流方法。预期结果是：（1）利用研究人员现有的实验测试台，用于计算、控制和配置未来无线电设备的能耗模型和设计框架，（2）用于非连续射频频谱的大规模认知访问的可配置无线电架构，以及（3）灵活、节能的认知无线网络的设计方法。更广泛的影响包括通过 WiFiUS 计划进行国际合作，为可配置频率捷变终端创建整体设计。独特的国际团队采用了一种新颖的跨学科方法，该团队建立在芬兰坦佩雷理工大学和奥卢大学、美国莱斯大学和马里兰大学专家之间的合作基础上。
