This Small Business Technology Transfer (STTR) Phase I project will involve research on and development of a reconfigurable wireless platform enabling secondary access of wireless spectrum via simultaneous data transmission across several disjoint frequency channels. In particular, the proposed innovations will advance the current state-of-the-art in the area of non-contiguous orthogonal frequency division multiple access (NC-OFDMA) architectures. The anticipated reduction in NC-OFDMA out-of-band emissions and transmitted peak-to-average power ratio will greatly improve the co-existence of primary and secondary wireless transmissions. The resultant improved dynamic spectrum access (DSA) capability will then permit much more efficient use of limited spectrum resources. The proposed work will be targeted towards the development of a high throughput and robust hardware implementation for the 802.22 wireless regional area network, a recently ratified Institute of Electrical and Electronics Engineers (IEEE) standard that employs NC-OFDMA. The research will result in an NC-OFDMA optimization framework that will help shape the direction of this field and guide the design of viable 802.22 products.The broader impact/commercial potential of this project stems from the opportunity to develop wireless products for the rural broadband and machine-to-machine markets. Data communication networks are needed by modern society for access to the Internet, providing both essential services and modern conveniences. Unfortunately, many communities, especially rural, currently lack the infrastructure to support such networks, with roughly three billion people in the world with little if any wireless service. Therefore, conducting research to optimize NC-OFDMA for high-speed communications systems including 802.22 in rural areas will benefit society while providing enormous commercialization potential. The optimization techniques and technology resulting from the proposed activities will also yield products for smart grids and sensor networks and support the public safety, emergency services, and first responder community efforts to provide better communications access to the network.

这项小型企业技术转移（STTR）第一阶段项目将涉及研究和开发一个可重新配置的无线平台，通过在多个不相交的频率信道上同时传输数据，实现无线频谱的二次接入。 特别地，所提出的创新将推进非连续正交频分多址（NC-0 FDMA）架构领域中的当前技术水平。 NC-OFDMA带外发射和发射峰均功率比的预期降低将极大地改善主无线传输和辅无线传输的共存。 由此产生的改进的动态频谱接入（DSA）能力将允许更有效地使用有限的频谱资源。 拟议的工作将针对802.22无线区域网络开发高吞吐量和鲁棒的硬件实现，802.22无线区域网络是最近批准的采用NC-OFDMA的电气和电子工程师协会（IEEE）标准。 该研究将产生一个NC-OFDMA优化框架，这将有助于塑造这一领域的发展方向，并指导可行的802.22产品的设计。该项目更广泛的影响/商业潜力源于为农村宽带和机器对机器市场开发无线产品的机会。 现代社会需要数据通信网络来访问互联网，提供基本服务和现代便利。 不幸的是，许多社区，尤其是农村社区，目前缺乏支持此类网络的基础设施，世界上大约有30亿人几乎没有无线服务。 因此，进行研究以优化用于农村地区的高速通信系统（包括802.22）的NC-OFDMA将有益于社会，同时提供巨大的商业化潜力。 从拟议的活动中产生的优化技术和技术也将为智能电网和传感器网络产生产品，并支持公共安全，应急服务和第一响应社区的努力，以提供更好的网络通信接入。
