    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaussian process; positioning; radio signals;

    Sammanfattning : Estimation of unknown parameters is considered as one of the major research areas in statistical signal processing. In the most recent decades, approaches in estimation theory have become more and more attractive in practical applications. LÄS MER

  5. 4. Radio Resource Management in Bunched Personal Communication Systems

    Författare :Miguel Berg; KTH; []
    Nyckelord :radio resource management; dynamic channel allocation; power control; interference avoidance; link-gain matrix; path-loss measurements; microcells; mobile positioning; trilateration;

    Sammanfattning : The traditional way of increasing capacity in a wirelesscommunication system has been cell splitting and fixedchannel-allocation based on prediction tools. However, theplanning complexity increases rapidly with the number of cellsand the method is not suitable for the large temporal andspatial traffic variations expected in the future. LÄS MER

  7. 5. Autonomous Localization in Unknown Environments

    Författare :Jonas Callmer; Fredrik Gustafsson; Paul Havinga; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Localization; indoor positioning; heading estimation; magnetometers;

    Sammanfattning : Over the last 20 years, navigation has almost become synonymous with satellite positioning, e.g. the Global Positioning System (GPS). On land, sea or in the air, on the road or in a city, knowing ones position is a question of getting a clear line of sight to enough satellites. LÄS MER
