1. 6. On Reconfigurable MEMS Antennas and Coupling Matrix Estimation

   Författare :Marc Mowlér; Björn Lindmark; Björn Ottersten; Pertti Vainikainen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunications; Antennas; Estimation Theory; Telecommunication; Telekommunikation;

   Sammanfattning : In this thesis, two different topics are treated related to wireless communication. Part I presents three different reconfigurable MEMS integrated antennas for MIMO applications. Simulation and measurement results are presented along with brief discussions on the topic of antenna selection with reconfigurable antenna elements. LÄS MER

3. 7. A Framework for the Coordination of Complex Systems’ Development

   Författare :Lars Taxén; Bengt Lennartsson; Roland Ekinge; Christian Berggren; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; system theory; telecommunication systems; framework; Activity Domain Theory; Computer science; Datavetenskap;

   Sammanfattning : This study is about the coordination of complex systems’ development. A Framework has been designed and deployed by the author in the development practice of Ericsson, a major supplier of telecommunication systems on the global market. The main purpose of the study is to investigate the impacts on coordination from the Framework. LÄS MER

   Sammanfattning : During the last decades the road traffic has increased tremendously leading to congestion, safety issues and increased environmental impacts. As a result, many countries are continuously trying to find improvements and new solutions to solve these issues. LÄS MER

7. 10. Cooperative and non-cooperative wireless access : Resource and infrastructure sharing regimes

   Författare :Johan Hultell; Jens Zander; Cristina Comaniciu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radio resource managment competition cooperation game theory; Telecommunication; Telekommunikation;

   Sammanfattning : Future wireless networks will combine multiple radio technologies and subsystems, possibly managed by competing network providers. For such systems it may be advantageous to let the end nodes (terminals) make some or all of the resource management decisions. LÄS MER
