ABSTRACT

 

Underwater acoustic channels are generally characterized as randomly
time-varying multipath channels. In this presentation, the
characteristics of these channels are described in terms of their
time-varying impulse response, time dispersion, frequency dispersion,
path loss and additive noise. Then, the design of
modulation/demodulation and coding/decoding techniques are considered,
including single carrier and multicarrier transmission, turbo
coding/decoding, and equalization for intersymbol interference. The
performance of these techniques are assessed from the viewpoint of
bandwidth efficiency and signal processing requirements.

 

SPEAKER'S BIOGRAPHY

 

Proakis received a bachelor's degree in electrical engineering from the
University of Cincinnati in 1959, a master's from MIT in 1961, and a
Ph.D. from Harvard University in 1967. He is an adjunct professor at UC
San Diego and a Professor Emeritus at Northeastern University, where he
was a faculty member 1969-1998. Prior to joining Northeastern
University, he worked at GTE Laboratories and the MIT Lincoln
Laboratory.

 

Proakis' professional experience and interests are in the general areas
of digital communications and digital signal processing. He is the
co-author of several books on signal processing and communication
systems.

 

Talk is sponsored by UCI's Center for Pervasive Communications and
Computing.
