Abstract: Wireless systems of the future must support ubiquitous multimedia communications
between people as well as devices. There are many research challenges associated with such
systems, including limited bandwidth, random variations in the wireless channel, and battery
constraints in small radio transceivers. Many of these challenges can be overcome with multiple
antennas at the transmitters and receivers of the wireless network, as well as node cooperation in
transmission, reception, and routing.
In this talk we will first explore the fundamental capacity limits and capacity achieving strategies
of wireless channels with multiple antennas. Of particular interest are asymptotic results on the
optimality of beamforming and the impact of quantized feedback for multiuser MIMO. Next we
consider fundamental capacity limits in wireless networks where nodes can cooperate in
transmission, reception, and routing. We propose novel cooperation techniques that approach
the capacity bounds, including virtual MIMO transmission, relaying, and conferencing. The
optimal cooperation strategy is cross-layer in nature and depends on the network topology, the
channel SNR, and the channel side information available at the nodes. Moreover, when the
network is constrained in energy or delay, cross-layer design is critical and leads to surprising
forms of cooperation.
Andrea Goldsmith is an Associate Professor of Electrical Engineering at Stanford
University, and was previously an Assistant Professor of Electrical Engineering
at Caltech. She has also held industry positions at Maxim Technologies and
AT&T Bell Laboratories. Her research includes work on capacity of wireless
channels and networks, energy-constrained wireless communications, wireless
communications for distributed control, and cross-layer design of wireless
networks. She received the B.S., M.S. and Ph.D. degrees in Electrical
Engineering from U.C. Berkeley.
Dr. Goldsmith is a Fellow of the IEEE and of Stanford, and currently holds
Stanford's Bredt Faculty Development Scholar Chair. She has received several
awards for her research, including the National Academy of Engineering Gilbreth
Lectureship, the Alfred P. Sloan Fellowship, the Stanford Terman Fellowship, the
National Science Foundation CAREER Development Award, and the Office of
Naval Research Young Investigator Award. She was also a co-recipient of the
2005 IEEEE Communications Society and Information Theory Society joint
paper award. Dr. Goldsmith has been active in committees, conference
organization, and editorial boards for the IEEE Information Theory and
Communications Societies. She is a member of the Board of Governors for both
societies, and is a Distinguished Lecturer for the Communications Society.
