Mark Oude Alink wins 'Else Kooi Prijs 2013'

Mark Oude Alink wins the 'Else Kooi prijs 2013' for his excellent research work done for his PhD thesis at the University of Twente which resulted in a 'cum laude' promotion.

Mark Oude Alink has done extensive research in the field of future wireless communication technologies. As the frequency spectrum is used more and more intensely for all sorts of wireless communication, it is becoming increasingly difficult to find free bands in the spectrum. This problem is becoming even more complicated due to the increasing number of wireless standards. The idea behind ‘Cognitive Radio’ is to scan the frequency spectrum for locally and temporally unused bands, known as spectrum holes or white space, and then opportunistically use those bands, until the ‘owner’ of the band starts transmitting, forcing the cognitive radio to hop to another unused frequency band. Mark Oude Alink has developed a technique to search for white space in the spectrum. In fact, he designed a tiny spectrum analyzer on-chip, normally a bulky and expensive piece of equipment sitting on a lab bench. He cleverly implemented mathematical techniques used in radio astronomy on an Integrated Circuit. His research was carried out at two groups at the CTIT institute: the IC-Design group led by Prof. Bram Nauta and the Computer Architecture for Embedded Systems group of Prof. Gerard Smit. Already in May, he earned his PhD title cum laude with his thesis ‘RF Spectrum Sensing in CMOS Exploiting Crosscorrelation’.

Else Kooi

The prize is named after Dr. Else Kooi (1932-2001) who became known due to an invention that was very important for the further development of Integrated Circuits. Already back in 1966 he invented LOCOS, LOCal Oxydation of Silicon, that enabled components on an IC to be placed more closely together. Dr. Else Kooi worked for Philips NatLab in Eindhoven and Philips Research Laboratories in Sunnyvale, Silicon Valley.
