				ABSTRACT

Normal factor graphs are a graphical representation of the factorization
of a function of several variables into a product of functions of a lower
number of variables. This representation yields efficient algorithms for
computing the marginals of the original function with respect to any one
of its variables. Originally developed for decoding turbo codes, it was
recognized that factor graphs are a natural setting for the description
of a number of general iterative and noniterative detection techniques.
In addition, they provide a unified framework that allows one to understand
the connections among seemingly different detection problems. This talk
illustrates the application of normal factor graphs to a number of these
problems, such as equalization of coded signals, multiuser detection,
and reception of space-time coded signals.

			   SPEAKER'S BIOGRAPHY

Ezio Biglieri received his training in electrical engineering from
Politecnico di Torino (Italy), where he received his Dr. Engr. degree in
1967. From 1968 to 1975 he was with Politecnico di Torino, first as a
research engineer, then as an associate professor. In 1975 he became a
professor of electrical engineering at the University of Napoli (Italy).
In 1977 he returned to Politecnico di Torino as a professor in the
department of electrical engineering. From 1987 to 1990 he was a professor
of electrical engineering at the University of California, Los Angeles.
Since 1990 he has again been a professor with Politecnico di Torino. He
was elected three times to the Board of Governors of the IEEE Information
Theory Society, and in 1999 he was the President of the Society. He is a
distinguished lecturer for the IEEE Information Theory Society and the
IEEE Communications Society. His honors include the IEEE Donald G. Fink
Prize Paper Award (2000), the IEEE Third-Millennium Medal for outstanding
contributions to the Information Theory area of technology (2000), and the
IEEE Communications Society Edwin Howard Armstrong Achievement Award
(2001). Currently he is serving as the Editor-in-Chief of the journal IEEE
Communications Letters. He is a Fellow of the IEEE.
