Research Areas

  • The audio and acoustics group has a tight connection to the study programme 'Electrical Engineering and Audio Engineering' which started in the 1970ies at the Department of Communications and Wave Propagation. The audio and acoustics group moved in 2002 to the Institute of Broadbandcommunications and relocated to the Signal Processing and Speech Communication Laboratory in 2011.

    The main topics are studio engineering, digital audio engineering, room acoustics electroacoustic and technical acoustics.

  • An intelligent system is able to perceive, learn, reason, and act in a prudent way. This involves various perception modalities such as input from cameras, microphones, sonar and other more exotic sensors. Furthermore, machine learning and pattern recognition techniques are important ingredients for reasoning under uncertainty in intelligent systems. One major aim is to extract relevant information from massive data in a semi-automatic fashion using computational and statistical methods.

  • Nonlinear Signal Processing is an emerging discipline combining knowledge from signal processing, adaptive systems, nonlinear dynamical systems, statistics and information theory, computation, and mixed-signal processing systems realization. Nonlinearity shows itself as a curse in many physical system realizations where analog effects may deviate strongly from their idealized linear behavior.

  • Speech Communication covers speech production and speech perception of the sounds used in spoken human language. It is a highly interdisciplinary field that is studied by several academic disciplines including acoustics, psychology, speech pathology, linguistics, cognitive science, communication studies, computer science, and signal processing. Research in Speech Communication at our lab focuses on automatic speech processing techniques for human-machine-interaction, for enhancing speech transmission, and for improving life quality of disabled persons.

  • Wireless Communications is a multidisciplinary subject, requiring expertise in radio propagation, antennas, RF electronics, analog and digital (mixed-signal) signal processing, systems theory, some control theory, and many mathematical topics, as statistics, coding theory, queuing theory, game theory, and others. Continuously, new topics have been emerging over the past years.
