     Exploiting Probabilistic Information for Spectrum Sensing
      and Utilization: towards Efficient Wireless Coexistence

With the rapid growth of wireless devices and applications, the
electromagnetic radio spectrum is considered to be in short
supply. To overcome spectrum scarcity and satisfy emerging user
demands, cognitive radio, which can sense and adapt to the
surrounding spectral environment, has been introduced to enhance
the utilization of the spectrum. However, it is a challenging
task to design a robust and cost-effective system involving
identification and reuse of spectrum opportunities changing over
time, frequency, and space. In this talk, I will focus on
efficient spectrum sensing and utilization techniques for dynamic
spectrum access. In particular, I will emphasize the importance
of exploiting probabilistic information unique to such a
system. I will present novel techniques from the perspectives of
both a single user and a multi-user network. In the end, I will
discuss further extension of the work to enable the coexistence
of heterogeneous wireless networks.


Xiangwei Zhou received his Ph.D. degree in Electrical and
Computer Engineering from Georgia Institute of Technology,
Atlanta, Georgia, in 2011.  He received his M.S. degree in
Information and Communication Engineering from Zhejiang
University, Hangzhou, China and his B.S. degree in Communication
Engineering from Nanjing University of Science and Technology,
Nanjing, China, in 2007 and 2005, respectively. Since 2013,
Dr. Zhou has been with the Department of Electrical and Computer
Engineering at Southern Illinois University Carbondale as an
Assistant Professor. Prior to that, he was a Senior Systems
Engineer with Marvell Semiconductor, Santa Clara, California,
from 2011 to 2013. Dr. Zhou's general research interests include
wireless communications and statistical signal processing, with
current emphasis on cognitive radio and heterogeneous
coexistence, cyber-physical systems, and cross-layer
optimization. He is now serving as an Editor for IEEE
Transactions on Wireless Communications.
