  1. 41. Enabling hardware technology for GNSS software radio research

    Författare :Marcus Junered; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : Software Defined Radio (SDR), has become an increasingly popular alternative to traditional radio technology. In principle the incoming radio frequency signal is sampled as close to the antenna as possible to minimize noise, distortion and other hardware related effects which degrade the signal quality.

  3. 42. First things first - think before you decide : The how, what and who of idea screening

    Författare :Johan Netz; Peter R Magnusson; Lars Witell; Lars E Olsson; Mette Præst Knudsen; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; idea screening; idea selection; idea evaluation; idea assessment; holistic assessment; innovation; intuition; criteria; Business Administration; Företagsekonomi;

    Sammanfattning : This thesis investigates decision-making activities leading to the initial selection of which new ideas should be selected for further development or rejected. This process, often referred to as idea screening, is described as being one of the most important, but also challenging, tasks to master during the entire innovation process. LÄS MER

  4. 43. Compact and Efficient Millimetre-Wave Circuits for Wideband Applications

    Författare :Lars Ohlsson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resonant-tunnelling diode; millimetre-wave spectrum; integrated transmitter; energy-efficiency; compact circuit; dielectric resonator antenna; transistor; wavelet generator; wideband.;

    Sammanfattning : Radio systems, along with the ever increasing processing power provided by computer technology, have altered many aspects of our society over the last century. Various gadgets and integrated electronics are found everywhere nowadays; many of these were science-fiction only a few decades ago. LÄS MER

  5. 44. Multiband LNA Design and RF-Sampling Front-Ends for Flexible Wireless Receivers

    Författare :Stefan Andersson; Christer Svensson; Marc Tiebout; Linköpings universitet; []

    Sammanfattning : The wireless market is developing very fast today with a steadily increasing number of users all around the world. An increasing number of users and the constant need for higher and higher data rates have led to an increasing number of emerging wireless communication standards. LÄS MER

  7. 45. Enabling Tool Support for Formal Analysis of ECA Rules

    Författare :AnnMarie Ericsson; Sten F. Andler; José Júlio Alferes; Linköpings universitet; []
    Nyckelord :ECA rules; Timed automata; Formal veri¯cation; TECHNOLOGY; TEKNIKVETENSKAP; Teknik;

    Sammanfattning : Rule-based systems implemented as event-condition-action (ECA) rules utilize a powerful and flexible paradigm when it comes to specifying systems that need to react to complex situation in their environment. Rules can be specified to react to combinations of events occurring at any time in any order. LÄS MER
