Best Student Paper Award at the IEEE
International Symposium on Information Theory (ISIT) held in Seoul,
Korea in June28-July 3, 2009, for the paper, "New Bounds on the Maximal
Error Exponent for Multiple-Access Channels," by Ali Nazari,

Mr. Nazari describes his research as being primarily focused on an
information theoretic approach to the problem of multi-terminal
"This rapidly growing field is applicable to diverse areas such as sensor
networks, video coding, mobile cellular networks, and packet switched
wireline networks," stated Nazari. "My research centers on reliability in
multiuser communication systems, such as wireless networks. In information
theory, the reliability of a single user system has been well studied.
However, there exists a large gap between a single user and a multiuser
system. This is primarily because the users cannot communicate while
transmitting data. Despite our knowledge about point to point systems,
little is known about multiuser systems since the previous bounds on the
reliability of multiuser systems do not have a similar structure."
this paper, we used a graph-based approach to obtain upper and lower bounds
of a similar structure. Our approach has facilitated further research on the
topic and has brought us one step closer to obtaining the exact value of the
reliability function in a multiuser communications systems."
