  1. 1. 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

  2. 2. Time of Flight Estimation for Radio Network Positioning

    Författare :Kamiar Radnosrati; Fredrik Gustafsson; Gustaf Hendeby; Simon Godsill; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

    Sammanfattning : Trilateration is the mathematical theory of computing the intersection of circles. These circles may be obtained by time of flight (ToF) measurements in radio systems, as well as laser, radar and sonar systems. A first purpose of this thesis is to survey recent efforts in the area and their potential for localization. LÄS MER

  3. 3. High frequency scattering and spectral methods

    Författare :Imad Akeab; Sven-Erik Sandström; Andreas Asheim; Linnéuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Waves and Signals; Vågor och signaler;

    Sammanfattning : This thesis consists of five parts. The first part is an introduction with references to some recent work on 2D electromagnetic scattering problems at high frequencies. It also presents the basic integral equation types for impenetrable objects and the standard elements of the method of moments. LÄS MER
