Welcome to the Intelligent Signal Processing research centre (ISPRC) at the Communications Department, Faculty of Electronics and Telecommunications, of the "Politehnica" University of Timisoara! ISPRC has been actively teaching courses, conducting research, and publishing results since 1986.


Current research interests are:

  • Adaptive signal processing
  • Coding
  • Compression
  • Data transmission
  • Time-frequency representations
  • Wavelets theory and applications
  • Nonlinear signal processing
  • Neural networks
  • Digital watermarking

In loving memory of Acad. Professor Adelaida Mateescu (1932-2008), the research lab of Signal Processing bears her name, under the aegis of Romanian Academy of Technical Sciences.
