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

    Författare :Fredrik Lindqvist; Institutionen för elektro- och informationsteknik; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : Swedish compulsory school has recently been subjected to a number of political reforms. Between 2011 and 2014, for example, earlier grades, more national tests and a new curriculum plan (Lgr 11) were to be implemented. This thesis aims to examine those changes as they were experienced by teachers who teach history in Swedish upper primary schools. LÄS MER
