Abstract

Abstract: In this talk, I try to show that thinking about energy efficiency is crucial when analyzing capacity or optimal signaling of some communication setup that seemingly has too many “degrees of freedom”. I will demonstrate this in the setup of optical multiple-antenna communication through air (MIMO freespace channel). Even though we focused on a theoretical capacity analysis for this channel model at the time, the insights we gained actually help also in very practical questions regarding how to signal on such channels.

Bio: Stefan M. Moser received the diploma (M.Sc.) in electrical engineering in 1999, the M.Sc. degree in industrial management (M.B.A.) in 2003, and the Ph.D. degree (Dr. sc. techn.) in the field of information theory in 2004, all from ETH Zurich, Switzerland. From 1999 to 2005, he was a research assistant with the Signal and Information Processing Laboratory at ETH Zurich, Switzerland, and from 2005 to 2013, he was a professor with the Department of Electrical and Computer Engineering at National Chiao Tung University (NCTU), Taiwan. Currently, he is a senior scientist with the Signal and Information Processing Laboratory at ETH Zurich and an adjunct professor with the Department of Electrical and Computer Engineering at National Yang Ming Chiao Tung University, Taiwan. Besides, he also teaches Mathematics at the Kantonsschule Uster. His research interests are in information theory and digital communications.
