KTH

The Royal Institute of Technology (KTH) in Stockholm is the leading engineering university in Sweden. At KTH the project will be coordinated by Wireless@KTH, a non-profit research center within the Royal Institute of Technology with financial backing from primarily by the Swedish Government, Research foundations and from an industrial partnership program. The center research area encompasses several research groups ranging from Antenna systems, Communication & Information Theory & Radio Resource management to Wireless Services, Network Management and the Economics of Telecommunications.

There are four areas of expertise at KTH that are relevant to the Quasar Project. KTH has played an internationally leading role in the development of Radio Resource Management Algorithms. Currently the focus in this area is on distributed, non-cooperative RRM, on novel wireless access infrastructure deployment techniques and schemes for competitive multi-operator access. The concept of “Cognitive Radio” was first developed at KTH by Joseph Mitola III in his Ph.D. thesis and joint publications with his advisor Prof Gerald Q Maguire Jr who will participate in an advisory capacity in the project.

KTH is also strong in wireless transmission and coding, with a reputation as world-leading in source-channel coding, multiple-antenna transmission, and iterative multiuser detection and decoding. More recently the focus has shifted toward cooperative communications, network coding, coordinated multipoint transmission, sensor networks, and network information theory. Ongoing activities include cooperative techniques for spectrum sensing to support cognitive radio and characterization of the fundamental tradeoffs between primary and secondary spectrum use, using tools from network information theory. The third area of expertise is business models and business impact for wireless access systems. Analyzing the cost structure of wireless infrastructure systems is an area where the center is among the leading academic institutions. KTH spearheaded these activities within the FP6 IP Ambient Networks. In the area of RF Measurement Technology, the nearby Center for RF-Measurement Technology at the University College of Gävle will be used as subcontractor. Its laboratory is equipped with state of the art instruments and measurement systems with the capability to measure from circuit level (load pull) to system level (field measurements).
