Research Topics

Digital Speech Processing:

  • speech and audio coding over mobile radio channels
  • low bit rate wideband speech coding
  • artificial wideband extension
  • combined acoustic echo cancellation and noise suppression
  • intelligibility enhancement
  • real time baseband processing

Mobile Radio Systems:

  • iterative demodulation and decoding
  • joint source channel decoding

  • wireless voice over IP

Medical Engineering:

  • electronic hearing aids in noisy environment
  • acoustic tube endoscopy

Peter Vary was the leader of the winning research team (Philips, IBM) which designed the GSM full-rate codec in 1988. Since 1990 the RWTH/IND group has a continuing tradition in contributing to international codec standards (GSM, UMTS, ITU). Furthermore, the group made numerous original proposals in the field of digital speech transmission which have opened new directions of academic research and industrial applications: e.g., combined echo cancellation and noise reduction, psychoacoustic noise reduction, artificial bandwidth extension, soft decision source decoding, iterative source-channel decoding, and turbo decodulation.
