    Sammanfattning : The concept of Channel Shortening (CS) is a well-known technique that has a rich history over 40 years. CS transfers linear vector channels such as multi-input multi-output (MIMO) and intersymbol interference (ISI) channels into ``shortened'' versions, for the purpose of reducing demodulation-complexity and improving data-transmission performance.

  3. 2. A Feasibility Study of Wireless Networks for 17 and 60 GHz and the Impact of Deployment Strategies on the System Performance

    Författare :Matthias Unbehaun; Jens Zander; Gerald Q. Jr. Maguire; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information technology; Informationsteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : This thesis addresses the question of how to deploy the infrastructure for wireless networks carrying high data rate services. It starts from the assumption that a major part of the costs for installing wireless infrastructure is caused by antenna site acquisition, planning of network coverage and capacity as well as manpower for setting up and wiring the antenna sites.
