Abstract

We are in the midst of a new wireless revolution, brought on by the adoption of wireless networks for consumer, military, scientific, and wireless applications. This revolution presents exciting new challenges due to the marked departure from the traditional additive white Gaussian noise channel paradigm. Recently, antenna diversity techniques have received considerable attention due to the significant information theoretic gains promised for multi-input-multi-output (MIMO) fading channels. Our research can be broadly categorized in three main thrusts: 1) Developing a unified algebraic coding theory for point-to-point MIMO fading channels, 2) Developing joint coding and scheduling algorithms for cellular MIMO channels, and 3) Developing cooperative (i.e. antenna sharing) schemes for ad-hoc MIMO channels. The first research thrust will develop bridges between different branches in Algebra and space-time coding. The cross fertilization between these two areas is expected to introduce useful algebraic tools in space-time coding research and formulate new problems of possible interest to the mathematical research community. The second and third thrusts will enhance the understanding of the information and coding theoretic foundations of cellular and ad-hoc MIMO channels. The education plan aims to expose students to the state of the art in wireless communications and provide the well-rounded training needed for both future academic jobs and leading-edge industrial positions.
