Our research is focused on adaptive signal processing with special focus on real-time application in speech communication in adverse environments, medical applications, and underwater systems.

Since 2010 the DSS group is developing KiRAT, an acronym that stands for Kiel Real-Time Application Toolkit. First, it was made for audio and speech processing. Meanwhile, it also supports medical und underwater applications.


The "Digital Signal Processing and System Theory" (DSS) team welcomes you on our homepage. Currently we consist of four professors or lecturers (Jan Abshagen, Ulrich Heute, Klaus Linhard, and Gerhard Schmidt), three secretaries (Carola Block, Kathrin Büsse, Petra Usinger), one system administrator (Kevin Prehn), about fifteen internal and external PhD students, as well as several master and bachelor students. More details about us can be found in our team section.

Our SONAR Simulator Supports Underwater Speech Communication Now

Due to the work of Owe Wisch and Alexej Namenas (and of the rest of the SONAR team, of course) our SONAR simulator supports now a real-time mode for testing underwater speech communication. A multitude of "subscribers" can connect to our virtual ocean and send and receive signals. The simulator consists of large (time-variant) convolution engine as well as a realistic noise simulation that ...
