The PHY is Dead: Long Live the PHY

Telecommunications advances are changing the way we live,
and PHY-layer research has been at the forefront of this revolution.
For the longest time, PHY was king.
But as time goes on, breakthroughs are becoming more rare. There is a growing sense that the PHY-layer technology has matured to the point where all of the important problems have been solved. We know how to modulate and demodulate and synchronize and code and decode and cancel interference. We know how to approach Shannon capacity and we know how to do so with low complexity. What's left? Is it true that the PHY is dead? This talk will explore these questions and assess the future of research at the physical layer.
Dr. received the B.S. degree from the State University of New York at Buffalo in 1986, and the M.S. and Ph.D. degrees from the University of California at Berkeley in 1987 and 1992, respectively, all in electrical engineering. His doctoral research explored the feasibility of broadband wireless communications using diffuse infrared radiation. Since 1985 he has held engineering positions in the fields of communications and radar systems at Bell Communications Research, IBM T.J. Watson Research Center, Hughes Aircraft Company, and General Dynamics. He is a coauthor of Digital Communication, Third Edition, Kluwer, 2004, and of Iterative Timing Recovery: A Per-Survivor Approach, VDM 2009, and he is the author of Wireless Infrared Communications, Kluwer, 1994. He received the 1992 David J. Griep Memorial Prize and the 1993 Eliahu Jury Award from U.C. Berkeley, a 1993 Research Initiation Award from NSF, and a 1993 IBM Faculty Development Award. He is currently serving as a Guest Editor for a special issue of the IEEE Journal on Selected Areas in Communications, and as the Techical Program Chair for IEEE Globecom 2013.
