  1. 1. Höra hemma : familj och social förändring i svensk radioserieteater från 1930-talet till 1990-talet

    Detta är en avhandling från Makadam förlag

    Författare :Amelie Björck; [2010]
    Nyckelord :HUMANIORA; HUMANITIES; 1900s; radio series; radio; radio serial; serial fiction; radio drama; radio theatre; family fiction; family history; home; gender history; intimacy; Swedish history; radio history; genre formation;

    Sammanfattning : Among the formats introduced in Swedish radio in the 1930s, the theatre series about contemporary family life has turned out an exceptional survivor. The first family series, ”Ingenjör Björck med familj” (1936-1943), was followed by 22 related series during the rest of the 20th century, each cultivating its own intimate and ritual based bond with the listeners.

  2. 2. Cognitive Radio Networks Elements and Architectures

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Alexandru Popescu; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cognitive radio network management; spectrum access; multiconstrained routing optimization; multi-dimensional adaptation; middleware;

    Sammanfattning : As mobility and computing becomes ever more pervasive in society and business, the non-optimal use of radio resources has created many new challenges for telecommunication operators. Usage patterns of modern wireless handheld devices, such as smartphones and surfboards, have indicated that the signaling traffic generated is many times larger than at a traditional laptop. LÄS MER

  3. 3. On Dynamic Spectrum Access in Cognitive Radio Networking

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Said Rutabayiro Ngoga; [2013]
    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

  5. 5. Performance Analysis of Cognitive Radio Networks with Interference Constraints

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Hung Tran; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio Networks; Spectrum Underlay Access; Interference Constraints; Cognitive Cooperative Radio Networks;

    Sammanfattning : To support the rapidly increasing number of mobile users and mobile multimedia services, and the related demands for bandwidth, wireless communication technology is facing a potentially scarcity of radio spectrum resources. However, spectrum measurement campaigns have shown that the shortage of radio spectrum is due to inefficient usage and inflexible spectrum allocation policies. LÄS MER
