Spectrum sharing under power constraints

Final Activity Report Summary - SPECTRUM SHARING (Spectrum Sharing under Power constraints)

During the stay at the University of California at Berkeley, more technical background and research experience in the field of spectrum sharing, adaptive embedded wireless networking and cognitive radio with power constraints was to be obtained. This stay at UC Berkeley included research projects, attendance of courses and research collaborations with all participants focussing on obtaining expertise in the broad field of spectrum sharing or cognitive radio. In the third year, the plan was to bring the acquired knowledge back to the Interuniversity Microelectronics Centre (IMEC) and disseminate it there by guiding PhD students in their work and defining new projects.

The expertise gained during the research visit to UC Berkeley allowed the researcher to actually obtain both technical and non-technical skills in guiding and coaching PhD students. This allowed him to coach students towards the end of their PhD, to engage in steering exiting PhD work, to start new PhD research and, equally importantly, to maintain a network of collaborations with PhD students across the world.

One of the main roles of a senior researcher in the wireless group at IMEC was the engagement in the definition and creation of new funded projects, both at national and European level. During the course of the third year of the fellowship, the researcher was involved in the following projects that were related to cognitive radio:

1. Flemish (IBBT) project on ‘next generation networks and terminals’
2. Flemish (IWT) project on ‘effective spectrum sensing enabling communication and economical stimulation’
3. European project (FP7) on ‘flexible and spectrum-aware radio access through measurements and modelling in cognitive radio systems’

The researcher was also involved in the preparation of several project proposals for future projects.

Finally, the experience at UC Berkeley allowed the researcher to define a set of relevant scenarios so as to specify the requirements of the sensing engine. Focus was on spectrum sensing in the unlicensed bands, but licensed bands such as the cellular bands, or TV bands were also considered.
