Abstract
The move to digital is a natural progression taking place in all aspects of broadcast
media. This is no less true for audio broadcasting which has taken a unique development
path in the United States. This path has been heavily influenced by a combination of
regulatory and migratory (from analog to digital) requirements specific for the U.S.
market. This has resulted in a unique set of requirements on source coding, channel
coding and digital modulation methods to make these systems a reality.
This talk outlines the technical development of the terrestrial wireless broadcasting
systems in the U.S. providing details on specific channel coding designs and adding
perspective on why specific designs were selected. AM and FM systems are about to be
introduced in the market place. These so called in band on channel systems are also
briefly compared to other systems such as Eureka 147 and DRM.

Carl-Erik W. Sundberg received the M.S.E.E. and the Dr. Techn. Degrees from the
University of Lund, Lund, Sweden in 1966 and 1975 respectively. From 1977 to 1984 he
was a Research Professor (Docent) in Telecommunication Theory, University of Lund.
From 1984 to 2000 he was a Distinguished Member of Technical Staff (DMTS) at Bell
Laboratories, Murray Hill, New Jersey, USA and during 2001 he was a DMTS at Agere
Systems, Murray. Currently he is a Senior Scientist at SundComm , Chatham, New
Jersey,USA and at iBiquity Digital Corp., Warren, New Jersey, USA. His research
interests include source and channel coding, digital modulation, fault-tolerant systems,
digital mobile radio, digital audio broadcasting, spread-spectrum, digital satellite systems
and optical communications. He has published over 95 journal papers and contributed
over 140 conference papers. He has 67 patents, granted and pending. He is a coauthor of
Digital Phase Modulation, (New York: Plenum, 1986), Topics in Coding Theory, (New
York: Springer-Verlag, 1989) and Source-Matched Digital Communications (New York:
IEEE Press, 1996).. In 1986 he received the IEEE Vehicular Technology Society’s Paper
of the Year Award and in 1989 he was awarded the Marconi Premium Proc. IEE Best
Paper Award. Two of his papers were selected for inclusion in the IEEE Communications
Society 50th Anniversary Journal Collection Volume 2002. Dr. Sundberg is a Fellow of
the IEEE and is listed in Marquis Who’s Who in America.
