  2. 1. Estimation and detection of transmission line characteristics in the copper access network

    Author : Fredrik Lindqvist; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital subscriber line; DSL; line qualification; twisted-pair line; copper access network; cable modeling; crosstalk channel estimation; estimation; detection;

    Abstract : The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. READ MORE

  5. 3. Copper Access Networks for Wireline and Wireless Services

    Author : Eduardo Medeiros; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In the last few years, technologies for broadband delivery over copper have dealt with increased capacity demands by using high frequencies and transmitter coordination, also known as vectoring. At the same time, to provide high capacity mobile broadband, operators have resorted to small cells. READ MORE

  6. 4. Wireline Communications in a Wireless World

    Author : Yezi Huang; Bredbandskommunikation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE

  7. 5. Common-Mode Aided Wireline Communications

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

    Abstract : 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.
