Here
is a matlab ASCII file of the impulse response
of the baseband prototype h(n) of a filter bank with N=1024
bands, filter length of 4096 taps, and a system delay of 2047
samples. The prototype is identical for analysis and synthesis,
and the modulating function is h_k(n)=h(n)*cos(pi/N*(k+0.5)(n+0.5+N/2))
for the analysis and g_k(n)=h(n)*cos(pi/N*(k+0.5)(n+0.5-N/2))
for the synthesis. |

Teaching |
|
I taught the course Signals and Transforms, EL611, at the
Brooklyn Polytechnic University, in 1999.
Since coming to Ilmenau I am co-teaching (with Karlheinz Brandenburg)
the course Audio Coding every winter semester at the Technical
University of Ilmenau, Germany.
For the summer semester 2005 and winter semester 2005/06 I
became temporary full professor at the Insitute of Media Technology
there, and taught the courses
- Übertragungssysteme (Communication Systems),
- Mediendistribution (Media Distribution),
- Praxiswerkstatt Algorithmen der Signalcodierung in Matlab
(Algorithms of Signal Coding in Matlab)
During winter semester 2005/06 I taught the courses
- Grundlagen der Videotechnik (Basics of Video Technology),
- Angew. Videostudiotechnik 1 (Applied Video Studio
Technology 1),
- Multimediale Werkzeuge 1 (Multimedia Tools 1),
- Audio Coding (in English, with Prof. Brandenburg)
Since sommer semester 2008 I am a full professor of the Technical University of Ilmenau, and part time member of Fraunhofer IDMT.
Links to those courses can be found here

Short Bio |
|
I studied mathematics in
Clausthal-Zellerfeld and Bonn, Germany, from 1981 to 1984,
and Electrical Engineering at the Technical University of
Berlin from 1984 to 1989. After finishing my studies with
the "Diplom" (M.S.) degree in Berlin I obtained a scholarship
for the Massachusetts Institute of Technology, Cambridge,
U.S.A., for the year 1989/90. Then I was a research assistant
at the Technical University of Berlin from 1990 to 1992, a
graduate student and teaching assistant at the Georgia Institute
of Technology, Atlanta, U.S.A., in 1993, and a research assistant
at the University of Bonn, Germany, in 1994. I was with the
University of Hannover, Germany, since 1995, where I received
my Ph.D. degree, with Bell Labs, Lucent Technologies, and
Agere Systems from 1998 to 2001, and am with the Fraunhofer
Institute, Group for Electronic Media Technology (AEMT), Ilmenau,
Ilmenau, since 2001. In January 2004 the Group for Electronic
Media Technology became the Institute for Digital Media Technology
IDMT. For the summer
semester 2005 and winter semester 2005/06 I became temporary
full professor
at the Insitute of Media Technology of the Technical University
of Ilmenau, Germany. Since sommer semester 2008 I am a full professor of the Technical University of Ilmenau, and part time member of Fraunhofer IDMT. |
