Integrative, Hybrid and Complex SystemsUniversity of WashingtonHui LiuDesign and Prototyping for Network ConvergenceThe objective of this research is to develop new network architectures for achieving convergence of digital broadcasting and (two-way) cellular data networks while delivering the quality-of-service necessary for multimedia distribution. The research approach is two-pronged. The first component is a joint design method for hybrid services to be natively supported in a collaborative cellular network. The second component of the research is a method for dynamic spectrum reuse within an extended cognitive radio (IEEE 802.22) framework.Intellectual Merit: This project addresses theoretical questions and associated system design issues underpinning the transition of next-generation digital broadcasting to broadband collaborative networks. The problems addressed are relevant to the recent availability of new radio frequency spectrum for broadcast and emerging industry standards, such as MediaFlo and Mobile WiMAX, that similarly seek an evolutionary path towards such a convergence. The project, while not specific to the above technologies and standards, is intended to result in cross-cutting commercial impact.Broader Impacts: The research seeks new architectures to provide significant capacity gains and spectrum saving in converged networks as compared to traditional, isolated wireless networks. Integral to this work is the cross-training of information technology professionals and scientists in communication and information theory as well as in networking and practical wireless system design. Further, the investigators plan to communicate results from this research to inform the IEEE Task Group 802.22 in its consideration of standards for network convergence.

集成，混合和复杂的SystemsUniversity of Washington Hui Liu网络融合的设计和原型本研究的目的是开发新的网络架构，实现数字广播和（双向）蜂窝数据网络的融合，同时提供多媒体分发所需的服务质量。 研究方法是双管齐下的。 第一个组成部分是用于在协作蜂窝网络中本地支持的混合服务的联合设计方法。 该研究的第二个组成部分是一个扩展的认知无线电（IEEE 802.22）framework.Intellectual Merit的动态频谱重用的方法：该项目解决的理论问题和相关的系统设计问题的基础下一代数字广播宽带协作网络的过渡。所解决的问题与最近用于广播的新的无线电频谱的可用性和新兴的工业标准（诸如MediaFlo和移动的WiMAX）有关，这些标准同样地寻求朝向这种融合的演进路径。该项目，虽然不是特定于上述技术和标准，是为了产生跨领域的商业影响。更广泛的影响：该研究寻求新的架构，以提供显着的容量增益和频谱节省在融合网络相比，传统的，孤立的无线网络。 这项工作的组成部分是信息技术专业人员和科学家在通信和信息理论以及网络和实际无线系统设计方面的交叉培训。此外，研究人员计划交流本研究的结果，以告知IEEE 802.22任务组在考虑网络融合标准时的情况。
