invite you to the following seminar:


Title: Coherence Diversity in Multi-User Networks

Speaker:  Prof. Aria Nosratinia
Electrical Engineering Department
University of Texas at Dallas

Date/Time: 18 March 2019, 4 PM

Venue: Golden Jubilee Seminar Hall, Dept. of ECE

Although links in a wireless network may easily experience different
coherence conditions, the literature in communication and information
theory has mostly concentrated on coherence intervals of equal length
throughout the network. This talk explores new and exciting developments
in the field of non-uniform fading dynamics, where the disparity of
fading intervals can lead to new gains in multi-user networks that are
distinct from previously known phenomena. Product superposition, a new
tool developed to address non-uniform dynamics, will be introduced.
We begin by studying the application of this tool in the 2-user
broadcast channel. The results will be extended to the multi-user
broadcast channel. Disparity in either coherence bandwidth, or both
coherence time & bandwidth, will be discussed. Time permitting, the
interplay with non-uniform or stale CSI, and the interactions of
product superposition with retrospective interference alignment will
be discussed.

Speaker’s Bio:
Aria Nosratinia is Erik Jonsson Distinguished Professor and
associate head of the Electrical Engineering Department at the
University of Texas at Dallas. He received his Ph.D. in Electrical
and Computer Engineering from the University of Illinois at
Urbana-Champaign in 1996. He has held visiting appointments at
Princeton University, Rice University, and UCLA.  His interests
lie in the broad area of information theory and signal processing,
with applications in wireless communication. Dr. Nosratinia is a
fellow of IEEE for contributions to multimedia and wireless
communications. He has served as editor and area editor for the
IEEE Transactions on Wireless Communications, and editor for the
IEEE Transactions on Information Theory, IEEE Transactions on
Image Processing, IEEE Signal Processing Letters, IEEE Wireless
Communications, and Journal of Circuits, Systems, and Computers.
He has received the National Science Foundation career award, and
the outstanding service award from the IEEE Signal Processing
Society, Dallas Chapter. He has served on the organizing committees
and technical program committees for a number of conferences, most
recently as the general co-chair of ITW 2018. He was named a highly
cited researcher by Clarivate Analytics (formerly Thomson Reuters).
