Efficient use of limited spectrum is emerging as a major issue in wireless systems. The proposed work focuses on technologies that provide better understanding of wireless networks and greatly enhance spectrum efficiency. with three coupled thrusts: (i) wireless network modeling; (ii) mechanisms for efficient spectrum sharing; and (iii) exploiting enhanced spectrum efficiency for wireless video communications. The project also includes an experimental research component in which the developed approaches will be implemented and tested on the cognitive radio testbed hosted at Virginia Tech and the cooperative networking testbed hosted at NYU-Poly.The proposed research plans to systematically investigate several of the unique technical challenges and open problems in enhancing radio spectrum efficiency, and supporting emerging video services. This fundamental research will support the development of technologies that achieve new levels of efficiency and quality in wireless broadband services, and will help alleviate the wireless bandwidth limits now being experienced. The work is supported by the Industry Advisory Board as well as individual industry members of the center and has the potential to extend the centers portfolio. The PIs plan to disseminate the work to their industry members and the broader industry and academic community via open-source software as wel as introduce the content within their degree and outreach programs.

有限频谱的有效利用正在成为无线系统中的一个主要问题。拟议的工作重点是能够更好地理解无线网络并大大提高频谱效率的技术。具有三个耦合的推动力：(i) 无线网络建模； (ii) 有效频谱共享的机制； (iii) 利用增强的频谱效率进行无线视频通信。该项目还包括一个实验研究部分，其中所开发的方法将在弗吉尼亚理工大学主办的认知无线电测试台和纽约大学理工学院主办的合作网络测试台上实施和测试。拟议的研究计划系统地研究几种独特的技术提高无线电频谱效率和支持新兴视频服务方面的挑战和未解决的问题。这项基础研究将支持技术的开发，使无线宽带服务的效率和质量达到新的水平，并有助于缓解目前遇到的无线带宽限制。这项工作得到了行业咨询委员会以及该中心各个行业成员的支持，并且有潜力扩展该中心的产品组合。 PI 计划通过开源软件向其行业成员以及更广泛的行业和学术界传播这项工作，并在其学位和推广计划中介绍这些内容。
