  1. 1. Multidimensional Constellation Shaping for Coherent Optical Communication Systems

    Författare :Ali Mirani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lattice-based constellations; geometric shaping; probabilistic shaping; multidimensional modulation format; Voronoi constellation; constellation shaping; optical communications; coherent receiver;

    Sammanfattning : To overcome the increasing demands for Internet traffic, exploiting the available degrees of freedom in optical communication systems is necessary. In this thesis, we study how constellation shaping can be achieved in various dimensions and how various shaping schemes affect the whole performance in real systems. LÄS MER

  3. 2. Traffic Control for VBR Video in Packet Switched Networks

    Författare :György Dán; KTH; []
    Nyckelord :Traffic control; VBR video; shaping; FEC; QoS;

    Sammanfattning : The best effort service offered by the Internet is notsatisfactory for the transmission of loss and delay sensitivedata, such as real-time voice and video. In order to provideservice guarantees at reasonably high load levels, additionalcontrol functions haveto be employed in the network. LÄS MER

  4. 3. Configuring and Analysing TSN Networks Considering Low-priority Traffic

    Författare :Bahar Houtan; Paul Pop; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : The IEEE Time-Sensitive Networking (TSN) standards offer a promising solution to deal with the challenge of supporting high-bandwidth, low-latency, and predictable communication in distributed embedded systems. Although TSN provides a gate mechanism to support the low-jitter transmission of high-priority time-triggered traffic, it also brings complexity to the network design as the configuration of such mechanism together with support for low-priority transmission is non-trivial.

  5. 4. Internet Video Transmission

    Författare :György Dan; Gunnar Karlsson; Viktória Fodor; Jean-Yves Le Boudec; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic control; MDC; FEC; Multicast streaming; Queuing theory; Telecommunication; Telekommunikation;

    Sammanfattning : The Internet has rapidly evolved from being a scientific experiment to a commercial network connecting millions of hosts that carries traffic generated by a large amount of applications with diverse requirements. Its architecture was however designed to enable efficient point-to-point delivery of bulk data, and can not provide statistical guarantees on the timely delivery of delay sensitive data such as streaming and real-time multimedia.

  7. 5. Teknik på bönders villkor : de tekniska och politiska aktörernas inflytande på den statsreglerade tekniska förändringen i Sverige 1806-1972

    Författare :Ulf Hamilton; Kent Zetterberg; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; History of technology; state technology; Göta Canal; railway; motor traffic; air transport; nuclear energy; technical actor; political actor; technical political actor; decision-making; History; Historia; historia; History;

    Sammanfattning : The dissertation deals with History of technology in Sweden before, during and after the industrialization. A theory that technical actors have a growing influence on state technology chiefly owing to the industrialization is presented. LÄS MER
