  1. 1. Common-Mode Aided Wireline Communications

    Författare :Thomas Magesacher; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; DSL; multicarrier modulation; DMT; Shannon capacity; channel modelling; common mode; wireline communications; information processing;

    Sammanfattning : Wireline communication is the Internet access technology with the largest number of subscribers worldwide. On physical-layer level, the traditional way to transmit signals at one end of a wire pair and to extract receive signals at the other end is to apply differential-mode signalling: transmit and receive signals correspond to voltage differences between the two wires.

  3. 2. Wireline Communications in a Wireless World

    Författare :Yezi Huang; Bredbandskommunikation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The whole society is digitalizing, filled with streaming services, cloud computing and an ambition of ubiquitous connectivity. To address the data demand, ultra-fast broadband, at the speeds of 1Gbps and more, is developed and deployed. Optical fibers have been long viewed as a future-proof carrier for the ultra-fast broadband. LÄS MER

  4. 3. Hybrid ARQ Using Serially Concatenated Block Codes for Real-Time Communication : An Iterative Decoding Approach

    Författare :Elisabeth Uhlemann; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-Time Communications; Hybrid ARQ; Iterative Decoding; QoS; Deadline Dependent Coding; Telecommunication theory; Telekommunikationsteori;

    Sammanfattning : The ongoing wireless communication evolution offers improvements for industrial applications where traditional wireline solutions causes prohibitive problems in terms of cost and feasibility. Many of these new wireless applications are packet oriented and time-critical. LÄS MER

  5. 4. On the practical feasibility of fair TCP communications in IEEE 802.11 based multihop ad hoc wireless networks

    Författare :Evgeny Osipov; []
    Nyckelord :;

    Sammanfattning : In the center of this dissertation is the question whether it is practically feasible to achieve deterministically good quality for traditional network services such as le transfer and Web browsing in multihop wireless mobile ad hoc networks (MANETs). Despite the straight forward benets of MANETs such as quick installation due to the absence of wireline infrastructure, and the virtue of dynamic re-conguration, these networks mainly exist in research labs so far.

  7. 5. Adaptive QoS-aware resource allocation for wireless networks

    Författare :Calin Curescu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : Wireless communication networks are facing a paradigm shift. From providing only voice communication, new generations of wireless networks are designed to provide different types of multimedia communications together with different types of data services and aim to seamlessly integrate in the big Internet infrastructure.
