  1. 11. The MISO Interference Channel as a Model for Non-Orthogonal Spectrum Sharing

    Författare :Johannes Lindblom; Erik G. Larsson; Eleftherios Karipidis; Wolfgang Utschick; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The demand for wireless communications services has increased during the last decades. To meet this demand, there is a need for allocating larger frequency bands. However, most of the frequency bands (or spectrum) suitable for wireless communication are occupied and allocated to licensed systems. LÄS MER

  3. 12. Sharing The Design Authorship Of Sustainability : Towards co-creation of sustainable transport systems and practices

    Författare :Liridona Sopjani; Sofia Ritzén; Jenny Janhager Stier; Sampsa Hyysalo; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-creation; design; sustainable transport systems; sustainable design; Machine Design; Maskinkonstruktion;

    Sammanfattning : Any separation between technology and society can be claimed to be artificial. Technological material systems are intertwined with human everyday life practices and ways of living, values, and belief systems. When we design and develop new technological systems, we are also designing opportunities for new daily living practices to emerge. LÄS MER

  4. 13. Radio Resource Sharing in Hierarchical Cellular Systems

    Författare :Robert S. Karlsson; KTH; []
    Nyckelord :;

    Sammanfattning : Hierarchical Cell Structures (HCSs) is generally believed tobe a solution to capacity problems of future mobilecommunication systems. In such systems we have a mix of cellsizes that handle different types of traffic. We can have largecells providing wide area coverage and small cells providinghigh capacity. LÄS MER

  5. 14. Decentralized Resource Sharing and Associationin in Wireless Networks

    Författare :Yuzhe Xu; Carlo Fischione; Sinem Coleri Ergen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In wireless networks, some of the most important supporting functionalities are decentralized resource sharing and association of clients to access points. These functionalities aim to optimally allocate the available wireless transmission resources, for example, time or spectrum channels, the transmit power, access points, and relaying opportunities, all of which are subject to availability constraints.

  7. 15. On the feasibility of unicensed operation in shared spectrum

    Författare :Olav Queseth; KTH; []
    Nyckelord :;

    Sammanfattning : Whether unlicensed operation is a feasible mode of operationin future infrastructures depends on a number of factors. Herea comparison is made between systems with exclusive licensesand cases where more than one system uses the same radiospectrum. LÄS MER
