This project seeks to develop the fundamentals of physical layerwireless multi-antenna communications to enhance and significantly impactthe design of current and future-generations of cellular telephony, personalcommunication services, and wireless local area networks.Fundamental limits of delay-sensitive wireless channels for realistic fadingmodels will be sought along with the development of innovative power- andspectrum-efficient methods for use over multi-antenna systems. These methodswill extract all the available spatial, temporal, and spectral degrees offreedom and diversity under practical constraints on cost and complexitythat are relevant for hand-held or laptop communication devices. To thisend, new performance criteria will be formulated based on which the analysisand optimization of various complexity-constrained communication schemeswill be carried out. The planned research will emphasize tight interactionsamong, and the discovery of new methods in, the information andcommunication theoretic foundations of fading channels and the associatedcoding, modulation and signal processing functions.

该项目旨在开发物理层无线多天线通信的基础知识，以增强并显着影响当前和未来几代蜂窝电话、个人通信服务和无线局域网的设计。真实衰落模型的延迟敏感无线信道的基本限制随着用于多天线系统的创新功率和频谱效率方法的开发，人们将寻求这种方法。这些方法将在与手持式或膝上型通信设备相关的成本和复杂性的实际限制下提取所有可用的空间、时间和频谱自由度和多样性。为此，将制定新的性能标准，在此基础上对各种复杂度受限的通信方案进行分析和优化。计划的研究将强调衰落信道的信息和通信理论基础以及相关编码、调制和信号处理功能之间的紧密相互作用以及新方法的发现。
