(4) 講演題目
Acoustic Signal Processing for Next-Generation Multichannel
Human/Machine Interfaces

(5) 講演概要
The acoustic interface for future multimedia and communication
terminals should be hands-free and as natural as possible, which
implies that the user should be free to move and should not need
to wear any devices.

For digital signal processing this poses major challenges both
for signal acquisition and reproduction, which reach far beyond
the current state of the technology.

For ideal acquisition of an acoustic source signal in noisy and
reverberant environments, we need to compensate acoustic echoes,
suppress noise and interferences and we would like to dereverberate
the desired source signal. On the other hand, for a perfect
reproduction of real or virtual acoustic scenes we need to create
desired sound signals at the listeners ears, while at the same time
we have to remove undesired reverberance and to suppress local noise.

In this talk we will briefly analyze the fundamental problems for
signal processing in the framework of MIMO (multiple input -
multiple output) systems and discuss current solutions. In accordance
with ongoing research we emphasize nonlinear and multichannel
acoustic echo cancellation, as well as microphone array signal
processing for beamforming, interference suppression, blind source
separation, and source localization.

Walter Kellermann is a professor for communications at the Chair of
Multimedia Communications and Signal Processing of the University of
Erlangen-Nuremberg, Germany. He received the Dipl.-Ing. (univ.) degree
in Electrical Engineering from the University of Erlangen-Nuremberg in
1983, and the Dr.-Ing. degree ('with distinction') from the Technical
University Darmstadt, Germany, in 1988.

From 1989 to 1990, he was a  Postdoctoral Member of Technical Staff 
at AT&T Bell Laboratories, Murray Hill, NJ. In 1990, he joined Philips
Kommunikations Industrie, Nuremberg, Germany.

From 1993 to 1999 he was a professor at the Fachhochschule Regensburg
before  he joined the University Erlangen-Nuremberg as a professor and
head of the audio research laboratory in 1999 (for more see
www.LNT.de/audio). In 1999 he co-founded the consulting firm DSP
Solutions.

Dr. Kellermann authored or co-authored 13 book chapters and more than
130 refereed papers in journals and conference proceedings. He served 
as an associate editor and as guest editor to various journals, a.o., 
to the IEEE Transactions on Speech and Audio Processing from 2000 to 
2004,and to the EURASIP Journal on Signal Processing. Presently he 
serves as associate editor to the EURASIP Journal on Advances in 
Signal Processing. He was the general chair of the 5th International 
Workshop on Microphone Arrays in 2003 and the IEEE Workshop on 
Applications of Signal Processing to Audio and Acoustics in 2005. He 
was the general co-chair of the 2nd International Workshop on Hands-
free Speech Communication and Microphone Arrays (HSCMA) in 2008. He 
was a 'Distinguished Lecturer of the IEEE Signal Processing Society' 
for 2007 and 2008. He currently serves as a Chair for the Audio and
Electroacoustics Technical Committee for the IEEE Signal Processing
Society.  He is an IEEE Fellow.

His current research interests include speech signal processing, array
signal processing, adaptive filtering, and its applications to 
acoustic human/machine interfaces.
