  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

  4. 2. High speed communication on twisted-pair wires and low complexity multiuser detectors

    Author : Frank Sjöberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : This thesis deals with two different topics: High speed communication on twisted pair wires (digital subscriber lines) and low complexity multiuser detectors. The major part of this thesis concerns a technique for high speed communication over the telephone network called Very high bit rate Digital Subscriber Line VDSL). READ MORE

    Author : Mikael Karlsson Rudberg; Linköpings universitet; []
    Keywords : ;

    Abstract : Techniques for providing users with high quality, high capacity digital transmission links has been in the research focus the last years. Both academia and industry try to come up with methods that can provide the consumers with high capacity transmission links at low price. READ MORE

  7. 5. The Zipper duplex method in very high-speed digital subscriber lines

    Author : Frank Sjöberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : This thesis deals with different aspects of digital subscriber lines (DSL). Over the years several DSL techniques for high-speed communication on the telephone access network have evolved that gradually have allowed higher data rates. READ MORE
