  1. 11. Offset-PLL based frequency up-conversion for low spurious transmission

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Anders Nilsson; [2003]
    Nyckelord :Electronics; Offset-PLL; low spurious; up-conversion; radio; transmitter; modulator; Elektronik;

    Sammanfattning : The goal of this final year project is to investigate various techniques to up-convert a baseband signal into radio frequency signals, and to investigate the practical problems encountered in an offset phase locked loop design by implementation. Phase locked loops are commonly used in radio transmitters and receivers to generate accurate RF signals from a low-frequency reference. LÄS MER

  3. 12. TCP Reaction to Rapid Changes of the Link Characteristics due to Handover in a Mobile Environment

    Master-uppsats, KTH/Teleinformatik

    Författare :Mattias Ronquist; [1999]
    Nyckelord :TCP; mobile IP;

    Sammanfattning : The Transmission Control Protocol (TCP), used in the Internet, was not developed for a mobile, wireless environment. One reason why TCP might encounter problems in such an environment is rapid changes of the link characteristics. These rapid changes can occur due to handover between two subnetworks (macro handover), e.g. LÄS MER
