ATR Adaptive Communications
Research Laboratories |
|
The ATR Adaptive
Communications Research
Laboratories were
established in March
1996, succeeding
the ATR Optical
and Radio Communications
Research Laboratories
and ATR Communications
Systems Research
Laboratories. With
a view to establish
technologies that
can be used easily
by anyone in any
communication environment,
four laboratories
are promoting research
in the following
areas: construction
and evaluation of
adaptive systems,
control of adaptive
communication, adaptive
spatial link technologies,
and advanced communication
devices. Five research
engineers from NHK
have been on loan
to the laboratory
to conduct joint
research on compound
semiconductors for
display/imaging
devices and optical
parallel signal
processing. They
have been working
toward the establishment
of basic technologies
for future broadcasting
use.
To be an open laboratory
for basic and creative
research has been
the basic principle
of ATR since its
establishment. A
variety of talented
people from a wide
range of specialized
fields, careers,
and nationalities
have participated
in the work done
at the Adaptive
Communications Research
Laboratories. A
number of accomplishments
have won high praise
internationally,
giving the Laboratories
recognition as a
COE on a global
scale. The ATR Adaptive
Communications Research
Laboratories will
continue to perform
an ever more important
role as one of the
largest institutions
for basic research
on IT-related technologies.

Cooperation with
Stanford University |
|
I have been working
on a one year term
as a visiting researcher
at Stanford University's
CSLI (Center for
the Study of Language
and Information)
since July 2000.
Presently, in cooperation
with Stanford University,
I am doing research
on an autonomously
distributed information
discovery system,
which automatically
retrieves the information
desired by a program
producer. In this
system, our goal
is not only to realize
information retrieval
from the massive
amount of networked
database including
the Internet, but
also to realize
the extraction and
summarization of
key information,
augmentation and
complementation
for missing data,
information management,
and presentation
in the best tailored
form for program
producers. A wide
range of technologies
will be required
in order to build
such a system, from
basic to applied.
To accomplish this,
we will continue
to promote work
on this research
theme, making the
best use of the
state-of-the-art
technologies belonging
to both the STRL
and Stanford University.

Research on Digital
Transmission Schemes for Terrestrial Broadcasting |
The launch of digital
terrestrial broadcasting
in Japan is expected
in 2003. Our study
group has concentrated
in the research
and development
of the ISDB-T digital
terrestrial broadcast
system. Currently,
with that aim of
achieving the implementation
of digital terrestrial
broadcasting, we
are conducting surveys
on reception characteristics
in Tokyo, Osaka,
and other cities
using actual transmission
facilities. We are
also researching
technical schemes
to improve those
reception characteristics.
A wide range of
research will continue
on the application
of digital terrestrial
broadcasting technologies
to other fields,
including ITS (Intelligent
Transport Systems),
and evolution of
post-ISDB-T broadcast
systems.
