Jean-Paul Linnartz is parttime professor in de Signal Processing Systems group at the Faculty of EE and a Research Fellow with Philips Research. His research interests include wireless networks for Intelligent Lighting Systems. He holds more than 50 granted patents and authored many scientific papers about electronic watermarks, anonymous biometrics, radio communications and Visual Light Communication. He was a faculty member at University of California at Berkeley and at Delft University of Technology. As a Senior Director, he headed research groups on security, on wireless connectivity and on IC design.
- Multi-Carrier CDMA (MC-CDMA). In 1993, the concept of MC-CDMA was first proposed as a combination of Orthogonal Frequency Division Multiplexing (OFDM) and Code Division Multiple access (CDMA). Since then, he paper has been cited many times, and MC-CDMA has become a well known modulation methods that is very suitable for frequency-selective wireless channels
- Mobile reception of Digital Television. In fact the OFDM modulation methods use by DVB-T are very susceptive to disturbances caused by fast motion of the antenna (such as, in a car on the Autobahn). Specific algorithms can counteract these effects and allow reliable reception
Electronic Watermarking and Security with Noisy Data
The research on electronic watermarking resulted in a monitoring and tracking system for TV broadcasts worldwide. By embedding a digital watermark that is invisible to the human eye (test confirmed that it even is imperceptible by Hollywood's golden eyes), advanced signal processing algorithms can recognize the content by detecting these watermarks. This system is currently offered by the spin-off Civolution and in use to track television news offered by international press agencies. Jean-Paul was awarded the "Fellow of IEEE" grade for leadership in security with noisy data. In particular he created solutions for storing biometric data, say, fingerprints, in a privacy-preserving way. It allows the verification of fingerprints by accessing a database, but conversely the stored data would not reveal what the finger print would be. Even an inside attack such a theft of a complete data base would not reveal the personal fingerprints. This led to the creation of the start-ups Priv-ID (now GenKey) and Intrinsic-ID.
Previously with the University of California at Berkeley
At Berkeley in the early 90s, his main research area was Wireless Communication. In particular, the team worked on car-to-car communication for Autonomous Vehicle Highway Systems in the California PATH program. Jean-Paul was principal investigator in the Infopad project, that worked on multimedia communication with small portable, handheld information pads. This work led, among other things, to a pioneering paper on Multi-Carrier CDMA, which has received a lot of attention in many international conferences afterwards.
Radio broadcasting has been a hobby during his studies. Jean-Paul worked with various radio stations in the Netherlands, in Belgium and on the Internet, as program host, producer and program manager. The ROZ, then part of the public Nederlandse Omroep Stichting (NOS), covered the province of Limburg from multiple transmit sites including a 100 kw FM transmitter in Roermond. Here he worked as program host.
Currently Jean-Paul runs the Internet radio "Euregio Radio".
