Results in brief
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.

Project objective
Over the last decades, the radio spectrum has been crowded by blooming wireless communication systems. To cope with the demand, new spectrum sharing paradigms are needed that also take energy limitations of mobile terminals into account.In this context, this proposal will jointly consider the design and implementation cost of advanced spectrum sharing algorithms over cognitive radios, to optimally trade-off system (transmission and computing) power and performance.The candidate is PhD student at IMEC on cross-layer optimization with realistic system-level power-performance models of WLAN and sensor networks. This research has led to a patent, and several journal and conference papers. The goal of this project is to broaden the scope to heterogeneous networks and cognitive radios.The targeted results on wireless spectrum sharing will strengthen expertise of the candidate in cross-layer optimization of future wireless networks. The host would be the top university UC Berkeley with several groups in the wire less domain (R.Broderson, J.Rabaey, A.Bahai), which are expected to have a large impact on the research of future cognitive radios and FCC spectrum regulations.It is a great opportunity for researchers to be present in UC Berkeley, to take part in and contribute to the early research in this promising field. The project will enable to extend previous work with the hosting Distributed Sensing Group based on an earlier stay.The European host IMEC is a research centre for training of PhD students and researchers, through European projects and bilateral collaborations with universities and companies. IMEC has expertise in wireless system design and implementation, with know-how and a hardware platform for power-optimized software-defined radio.Broadening this knowledge towards cognitive radio and spectrum sharing will enable IMEC to extend its role as leading research institute in the field. IMEC is interested to strengthen the liaison with UC Berkeley.
