  1. 21. Partial Response and Faster-than-Nyquist Signaling

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Fredrik Rusek; Lunds universitet.; Lund University.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication engineering; Signalbehandling; Signal processing; Partial Response Signaling; Faster-than-Nyquist Signaling; Digital Communications; Coding Theory; Telekommunikationsteknik;

    Abstract : Bandwidth efficiency is a key objective in the design of a digital communication system. Traditionally it is accomplished by increasing the constellation size of the signaling system. In this thesis alternative techniques are studied. Because the communication channel is continuous, so must the actual time signals be. READ MORE

  2. 22. Bluetooth and Wireless Multihop Networks in Industrial Communication Systems

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Urban Bilstrup; Högskolan i Halmstad.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Information technology Computer engineering; TEKNIKVETENSKAP Informationsteknik Datorteknik; TECHNOLOGY Information technology Telecommunication Datatransmission; TEKNIKVETENSKAP Informationsteknik Telekommunikation Datatransmission; Bluetooth; industrial communication systems; short range devices; wireless multihop networks; wireless sensor networks; real-time communication; resource allocation;

    Abstract : The objective of this thesis is to investigate the use of short-range wireless communication technology in industrial communication systems where there is a need for guaranteed timely delivery of correct information. Methods for achieving such capability are developed in the context of the physical layer, the data link layer and the application layer. READ MORE

  3. 23. Error and Traffic Control for High-Speed Networks

    University dissertation from Stockholm : KTH

    Author : Henrik Lundqvist; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; TECHNOLOGY Information technology Telecommunication; TEKNIKVETENSKAP Informationsteknik Telekommunikation;

    Abstract : The Internet evolves rapidly, both in terms of the applications that use it and the networks that carry the traffic. This creates many important research tasks, both to adapt the networks that carry the traffic to work well together with the Internet protocols and to make the protocols robust to tolerate various underlying networks.

  4. 24. Dynamic modeling of Internet congestion control

    University dissertation from Stockholm : KTH

    Author : Krister Jacobsson; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Congestion control; TCP; Control theory; Fluid flow modeling; Internet; Telecommunication; TECHNOLOGY Information technology Telecommunication; TEKNIKVETENSKAP Informationsteknik Telekommunikation;

    Abstract : The Transmission Control Protocol (TCP) has successfully governed the Internet congestion control for two decades. It is by now, however, widely recognized that TCP has started to reach its limits and that new congestion control protocols are needed in the near future. READ MORE

  5. 25. NFV Service Chains at the Speed of the Underlying Commodity Hardware

    University dissertation from Kista, Stockholm, Sweden : KTH Royal Institute of Technology

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NFV; service chains; synthesis; offloading; tagging; zero inter-core communication; line-rate; 100GbE; NFV; tjänstekedjor; syntetisering; processavlastning; paketmärkning; ingen inter-CPU-kommunikation; länkkapacitet; 100GbE; Datalogi; Computer Science; Informations- och kommunikationsteknik; Information and Communication Technology; Telecommunication; Telekommunikation;

    Abstract : Link speeds in networks will in the near-future reach and exceed 100 Gbps. While available specialized hardware can accommodate these speeds, modern networks have adopted a new networking paradigm, also known as Network Functions Virtualization (NFV), that replaces expensive specialized hardware with open-source software running on commodity hardware.
