To Infinity and Beyond: New Frontiers in Wireless Information Theory

2014 ISIT Plenary Lecture
To Infinity and Beyond: New Frontiers in Wireless Information Theory
Andrea Goldsmith
Stanford University

Signal Processing

Although wireless information theory has been declared dead many times over, the field today is thriving with abundant open problems of significant theoretical and practical importance. This talk will explore our recent results on wireless information theory that go towards infinity in the number of users, and back from infinity in other dimensions. In particular, we will describe our work on achievable rate regions for single-hop networks with any number of users, obtained through user virtualization followed by coding via a graphical Markov model. The resulting achievable rate regions meet or exceed all existing rate regions for any single-hop network, including those of interference channels, broadcast channels, and cognitive radio channels. Moving back from infinity, we examine the implications of finite delay, energy, feedback, and sampling with a particular focus on our results unveiling rate-distortion theory and channel capacity for sub-Nyquist sampled sources and channels. We end the talk describing additional dreams and challenges in wireless information theory, including the application of information-theoretic analysis tools to explore new frontiers in biology and neuroscience.



Andrea Goldsmith is the Stephen Harris professor in the School of Engineering and a professor of Electrical Engineering at Stanford University. She was previously on the faculty of Electrical Engineering at Caltech. She co-founded and served as CTO of Accelera, Inc. and of Quantenna Communications, Inc. and has also held industry positions at Maxim Technologies, Memorylink Corporation, and AT&T Bell Laboratories. Dr. Goldsmith is a Fellow of the IEEE and of Stanford, and she has received several awards for her work, including the IEEE Communications Society and Information Theory Society joint paper award, the IEEE Communications Society Best Tutorial Paper Award, the National Academy of Engineering Gilbreth Lecture Award, the IEEE ComSoc Communications Theory Technical Achievement Award, the IEEE ComSoc Wireless Communications Technical Achievement Award, the Alfred P. Sloan Fellowship, and the Silicon Valley/San Jose Business Journal's Women of Influence Award. She is author of the book "Wireless Communications" and co-author of the books "MIMO Wireless Communications" and "Principles of Cognitive Radio," all published by Cambridge University Press.

She received the B.S., M.S. and Ph.D. degrees in Electrical Engineering from U.C. Berkeley. Dr. Goldsmith has served as editor for the IEEE Transactions on Information Theory, the Journal on Foundations and Trends in Communications and Information Theory and in Networks, the IEEE Transactions on Communications, and the IEEE Wireless Communications Magazine as well as on the Steering Committee for the IEEE Transactions on Wireless Communications. She participates actively in committees and conference organization for the IEEE Information Theory and Communications Societies and has served on the Board of Governors for both societies. She has also been a Distinguished Lecturer for both societies, served as President of the IEEE Information Theory Society in 2009, founded and chaired the student committee of the IEEE Information Theory Society, and chaired the Emerging Technology Committee of the IEEE Communications Society. At Stanford she received the inaugural University Postdoc Mentoring Award and has been active in committees to innovate and revise both graduate and undergraduate education university-wide. She served as Chair of Stanford's Faculty Senate in 2009 and currently serves on its Faculty Senate and on its Budget Group.
