  2. 1. Localization using Distance Geometry : Minimal Solvers and Robust Methods for Sensor Network Self-Calibration

    Author : Martin Larsson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; localization; TDOA; TOA; trilateration; multilateration; distance geometry; registration; sensor network self-calibration;

    Abstract : In this thesis, we focus on the problem of estimating receiver and sender node positions given some form of distance measurements between them. This kind of localization problem has several applications, e.g. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Time of Flight Estimation for Radio Network Positioning

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

    Abstract : 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. READ MORE

  6. 4. High frequency scattering and spectral methods

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

    Abstract : 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. READ MORE
