  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.
