This project will investigate interfering cellular networks, which are networks formed by operating multiple cells of a traditional cellular network over the same frequency. In particular, it will develop efficient communication schemes for such networks that (a) deal with interfering data flows between multiple source-destination pairs (b) include cooperative strategies between nodes to exploit resources such as a wired back bone of constrained capacity and connectivity between access points and (c) robustly cope with channel uncertainty. Throughout, approximated capacity characterizations or those that are amenable to computation will be sought, with an emphasis on methods that scale well to a larger number of users.The goal is to develop improved alternatives to communication methods employed in current cellular networks. The importance of such improved methods in the design of future generations of these networks is evident from the e-commerce that such networks enable, the information they make easily accessible and the increased efficiency of organizations they make possible today.

该项目将研究干扰蜂窝网络，这些网络是通过以相同频率操作传统蜂窝网络的多个小区而形成的网络。特别是，它将为此类网络开发有效的通信方案，该方案（a）处理多个源-目的地对之间的干扰数据流（b）包括节点之间的协作策略，以利用资源，例如容量有限的有线骨干和节点之间的连接性接入点；(c) 稳健地应对信道不确定性。在整个过程中，将寻求近似的容量特征或那些易于计算的特征，重点是能够很好地扩展到大量用户的方法。目标是开发当前蜂窝网络中使用的通信方法的改进替代方案。这些改进的方法在未来几代网络的设计中的重要性从这些网络所支持的电子商务、它们使信息易于访问以及它们使当今的组织效率提高中可以明显看出。
