Achievements

International and collaborative research projects

  1. Participation in the European Union 5th Framework Research Project WIND-FLEX (Wireless Indoor Flexible High Bitrate Modem Architectures).
  2. Participation in the European Union 6th Framework Integrated Research Project WINNER (Wireless World Initiative New Radio) since January 2004 and WINNER II (since January 2006).
  3. Participation in the European Union 6th Framework Network of Excellence NEWCOM (Network of Excellence in Wireless Communications) since January 2004.
  4. Participation (2003-2005) in the European Union international Leonardo da Vinci project INVOCOM (Internet-based vocational training of communication students, engineers, and technicians) which focused on the preparation of interactive educational material that covered the selected areas of electronics and telecommunications. (www.invocom.et.put.poznan.pl).
  5. Development of the Embedded Deterministic Test (EDT) technology for test data compression; a paper describing this technology has been selected as one of the most influential papers published at the IEEE International Test Conference (ICT) in the last 35 years and, in particular, the most significant paper presented at the ITC in 2002; the main archival paper presenting the EDT technology won the IEEE Circuits and Systems Society Donald O. Pederson award recognizing the best paper published in the IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems in 2004 – 2005; the EDT technology has been incorporated in the first commercial on-chip test compression product – TestKompress® marketed by Mentor Graphics Corporation – a world leader in electronic hardware and software design solutions providing EDA products for semiconductor companies; TestKompress® received three industrial awards: Best in Test of the Test and Measurement world magazine (the best product of the year 2001), Product of the Year of the Electronic Products magazine, Hot 100 Products 2001 of the EDN Access magazine.
  6. Co-ordination of two EU international Leonardo da Vinci projects. The project titles are the following: Vocational training for certification in ICT (Train2Cert) and International certificates of excellence in selected areas of ICT (InCert) (www.incert.eu and www.train2cert.eu).
