   Sammanfattning : This thesis regards datapath design and analysis at several abstraction levels. Five papers are presented that focus on datapath design for mobile communication systems and design methodologies for such datapaths. Paper I discusses different aspects of Turbo channel decoder design for high speed and low power applications. LÄS MER

4. 3. Between Daring and Deliberating : 3G as a Sustainability Issue in Swedish Spatial Planning

   Författare :Stefan Larsson; Rättssociologiska institutionen; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; 3G; UMTS; spatial planning; sociology of law; sustainability issues; sustainable development; public participation; infrastructure development; the precautionary principle; fear of radiation; strategic decision-making; sociology of law; sustainable development; infrastructure development; strategic decision-making; fear of radiation; public participation; the precautionary principle; spatial planning; sustainability issues; UMTS; 3G;

   Sammanfattning : The thesis shows how different aspects of sustainable development have been handled or not handled in the third generation infrastructure development in Sweden. The difference between the design of the 3G development – emphazising competition, growth and regional access, based on a strong technological optimism - and the implementation, as the roll out struck the landscape, including the non-handled radiation issue and the legal changes in order to facilitate the roll out, is discussed and analyzed.
