In 2000, the Signal Processing and Speech Communication Laboratory (SPSC Lab) of Graz University of Technology (TU Graz) was founded as a research and education center in nonlinear signal processing and computational intelligence, algorithm engineering, as well as circuits & systems modeling and design, and covers applications in wireless communications, speech/audio communication, and telecommunications.

The lab has built up a broad knowledge base on signal processing methods for mixed-signal systems and circuits. Fundamental work has been done on adaptive identification of nonlinear mixed-signal systems, nonlinear multi-rate signal processing, digital calibration of data converters, advanced algorithms for ultra wideband communications and all-digital phase-locked loops, adaptive digital predistortion for nonlinear power amplifiers, and reconfigurable radio terminals.

Other work of the lab addresses speech and audio communication, in particular automatic document creation and media mining using speech recognition, speaker identification, separation, and localization using microphone arrays, machine learning algorithms and sensor network applications.
