  1. 16. Culture and Transmission : The Technological and Cultural Reach of International Syndicated Radio

    Författare :Lars Lundgren; Jan Ekecrantz; Göran Bolin; Arnt Maasø; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; culture; technology; transmission; space; time; radio; Internet; music; sound; media production; Media and communication studies; Medie- och kommunikationsvetenskap; Communication Studies; medie- och kommunikationsvetenskap;

    Sammanfattning : The aim of this dissertation is to study the technological and cultural reach of internationally syndicated radio from the vantage point of the radio programme Solid Steel between 2000 and 2006. Solid Steel is a weekly two-hour music show originally produced and aired in London but today also broadcast by a large number of stations around the world, as well as via the Internet. LÄS MER

  3. 17. Uplink Load in CDMA Cellular Radio Systems

    Författare :Erik Geijer Lundin; Fredrik Gunnarsson; Oriol Sallent; Linköpings universitet; []
    Nyckelord :CDMA; Uplink Load; Radio Resource Management; Automatic Control; Cellular Radio; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The uplink of code division multiple access (CDMA) cellular radio systems is often interference limited. The interference originates from many users whose transmission powers are not observable for the system. LÄS MER

  4. 18. Model-Based Cognitive Radio Strategies

    Författare :Kasra Haghighi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spectrum utilization; cognitive radio; censorship; CLAPP; sequential detection;

    Sammanfattning : Many frequency bands for wireless services are severely underutilized by the primary users (PU) to which these bands are assigned. This motivates a new class of wireless communication devices known as cognitive radios (CR), which identify vacant spectrum and transmit accordingly. LÄS MER

  5. 19. On Dynamic Spectrum Access in Cognitive Radio Networking

    Författare :Said Rutabayiro Ngoga; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio; Cognitive Radio Networking; Dynamic Spectrum Access; Wireless Communications;

    Sammanfattning : The exploding increase of wireless communications combined with the existing inefficient usage of the licensed spectrum gives a strong impetus to the development and standardization of cognitive radio networking and communications. In this dissertation, a framework for Dynamic Spectrum Access (DSA) is first presented, which is the enabling technology for increasing the spectral efficiency of wireless communications. LÄS MER
