Introduction of the Research Group

Our aim is the development and research of signal processing methods, and, besides, the utilization of high-level knowledge in measurement technology, electronics. The speciality of our laboratory is the application of digital signal processing to acoustic problems. Active noise control is one of the first research works that has been shortly accompanied by sound synthesis and audio signal processing. The research is supported by the equipment of the laboratory comprising more and more vibroacoustic sensors and other instruments.

Another important research field is the frequency domain identification and some related topics, like parameter estimation, linear and nonlinear system identification. Research and development covers the field of baseband complex signal processing in wireless systems, especially in the topics of 5G modulation, channel estimation and parameter estimation.

Achievements

  • Audio filter design: Investigation of finite wordlength effects of fixed-pole parallel filters, their extension for MIMO systems. New methods for conversion of IIR filters to second order sections based on direct or serial form.
  • Development of a noise canceling office chair, investigation of active noise control systems with multiple reference signals.
  • Adaptive systems: Exhaustive investigation of the observer-based adaptive Fourier analyzer.
  • Distributed systems: New method for spectral estimation in the case of data loss, frequency domain identification of data loss models
