  1. 11. Extraction of radio frequency quality metric from digital video broadcast streams by cable using software defined radio

    Master-uppsats, Kommunikationssystem; Tekniska högskolan

    Författare :Viktor Eriksson; [2013]
    Nyckelord :QAM; DVB-C; MER; BER; Gardner; Phase locked loop; Mueller Muller; RRC-filter; Carrier recovery; Timing Recovery; Matched filtering;

    Sammanfattning : The purpose of this master thesis was to investigate how effiecient the extractionof radiofrequency quality metrics from digital video broadcast (DVB) streamscan become using software defined radio. Software defined radio (SDR) is a fairlynew technology that offers you the possibility of very flexible receivers and transmitters where it is possible to upgrade the modulation and demodulation overtime.

  3. 12. Exploiting Dynamic Privacy in Socially Regularized Recommenders

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Ramona Bunea; [2012]
    Nyckelord :;

    Sammanfattning : Users of social networks have shown an increasing concern for exposing their personal data to untrusted entities in order to receive recommendations. In this work, we describe the components of a privacy-aware collaborative filtering based recommender framework which targets two important issues in recommender systems operating in a social network: privacy concern of profile owners and sparsity of social trust among users in a social network.
