The overarching goal of wireless communication research is to develop techniques to combat channel uncertainties intrinsic to wireless systems, and to provide high speed reliable and secure transmissions for mobile users. Towards this goal, multiple-input multiple-output (MIMO) transmission, cooperative relaying, and information-theoretic security are emerging as powerful techniques for improving the throughput, reliability and security of wireless networks. In this talk, I will first overview the goals for wireless communications and the challenges ahead in exploring the performance advantages provided by the techniques of MIMO transmission, cooperative relaying, and information theoretic security. Within the context of this overview, I will describe the research projects I have being pursuing, including optimal schemes for noncoherent wireless communications, capacity of correlated MIMO channels, resource allocation for wireless relay channels; impact of user cooperation and relaying on broadcast networks, and information theoretic approaches to achieve secure wireless communications.
