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.
