I/UCRC: Collaborative Research: Unlocking Spectrum Efficiency for Future Wireless Networks

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。拟议的工作重点是提供更好地了解无线网络并极大地提高频谱效率的技术。通过三个耦合的推进：(I)无线网络建模；(Ii)高效频谱共享的机制；以及(Iii)为无线视频通信利用增强的频谱效率。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托管的认知无线电试验台和纽约大学理工学院托管的合作网络试验台上实施和测试。拟议的研究计划系统地调查在提高无线电频谱效率和支持新兴视频服务方面的几个独特的技术挑战和公开问题。这项基础研究将支持在无线宽带服务中实现效率和质量的新水平的技术开发，并将有助于缓解目前正在经历的无线带宽限制。这项工作得到了行业咨询委员会以及该中心个别行业成员的支持，并有可能扩大该中心的投资组合。私人投资机构计划通过开源软件将工作传播给他们的行业成员以及更广泛的行业和学术界，并在他们的学位和推广计划中介绍这些内容。

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.
