Example, efficient low delay filter banks

• Structure of a modulated low delay analysis filter bank

• Structure of a modulated low delay synthesis filter bank for perfect reconstruction

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.

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, since 2001.

In January 2004 the Group for Electronic Media Technology became the Fraunhofer 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.

I taught the course "Signals and Transforms, EL611", at the Brooklyn Polytechnic University, in 1999.
Since coming to Ilmenau I am co-teaching (with Prof. Dr. 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.
