With the rapid proliferation of wireless devices in the last decade, it has become increasingly important to efficiently utilize limited spectrum resources through close coordination of devices in the network. While several advanced techniques have been developed recently to address this problem, these techniques require an accurate and consistent view of the channel states as well as some degree of synchronization among the devices in the network to be effective. The research plan in this project is focused on developing an analytical framework and efficient techniques for channel state dissemination and network synchronization to enable close coordination of devices in a network and efficient utilization of the channel resources. The proposed research is based on the view that, in order to determine the best use of the spectral and temporal resources available to the network, channel state estimation and dissemination should be performed continuously as part of the normal network operation. By estimating and disseminating network channel state information continuously through existing network traffic, devices in the network can adaptively determine an appropriate network structure and mitigate the effects of interference to facilitate efficient communication under current and predicted channel states.The foundational nature of the research plan makes it broadly applicable in a wide range of wireless communication systems such as cellular networks, wireless local area networks, vehicular networks, and emergency communication systems. The analytical framework and techniques for efficient channel state dissemination and network synchronization developed on this project will impact emerging wireless communication systems such as informed-transmitter multi-input multi-output (MIMO), cognitive radio, cooperative relaying, distributed transmission, and interference alignment. The proposed research will establish a solid theoretical foundation for understanding the limits of minimum-staleness channel state dissemination and clock synchronization in wireless networks and will also include experimental verification through testbed implementations of the channel state dissemination and network synchronization techniques.

随着过去十年中无线设备的快速扩散，通过网络中的设备的密切协调，有效利用有限的频谱资源变得越来越重要。 尽管最近已经开发了几种高级技术来解决此问题，但这些技术需要对渠道状态的准确，一致的视图以及网络中的设备之间的一定程度同步才能有效。该项目中的研究计划的重点是开发一个分析框架和有效的技术，用于通道状态传播和网络同步，以使网络中的设备紧密协调以及对渠道资源的有效利用。拟议的研究基于这样的观点，即为了确定网络可用的光谱和时间资源的最佳利用，应作为正常网络操作的一部分连续执行信道状态估计和传播。通过通过现有的网络流量连续估算和传播网络通道状态信息，网络中的设备可以自适应地确定适当的网络结构，并减轻干扰的影响，以促进在当前和预测的渠道状态下有效的沟通。研究计划的基础性质使其广泛地适用于广泛的无线通信系统，例如无线网站，无线网络网络，以及当前的网络网络，车辆，车辆和车辆。在该项目上开发的有效渠道状态传播和网络同步的分析框架和技术将影响新兴的无线通信系统，例如知情的传播者多输入多输出（MIMO），认知无线电，合作收射，分布式，分布式传输和干扰一致性。 拟议的研究将建立一个可靠的理论基础，以理解无线网络中最小值通道状态的传播和时钟同步的限制，还将包括通过测试台式实现通道状态传播和网络同步技术的实验验证。
