  2. 1. Power Control in Cellular Radio Systems : Analysis, Design and Estimation

    Author : Fredrik Gunnarsson; Fredrik Gustafsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The primary goal of cellular radio systems is to provide communications services to a large number of mobile users. Due to the dramatic increase in number ofusers and their demand for more advanced services, the available resources haveto be utilized efficiently. READ MORE

  4. 2. Rao-Blackwellised particle methods for inference and identification

    Author : Fredrik Lindsten; Thomas Schön; Lennart Ljung; Fredrik Gustafsson; Tobias Rydén; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : We consider the two related problems of state inference in nonlinear dynamical systems and nonlinear system identification. More precisely, based on noisy observations from some (in general) nonlinear and/or non-Gaussian dynamical system, we seek to estimate the system state as well as possible unknown static parameters of the system.

  5. 3. Particle filters and Markov chains for learning of dynamical systems

    Author : Fredrik Lindsten; Thomas B. Schön; Lennart Ljung; Fredrik Gustafsson; Arnaud Doucet; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bayesian learning; System identification; Sequential Monte Carlo; Markov chain Monte Carlo; Particle MCMC; Particle filters; Particle smoothers;

    Abstract : Sequential Monte Carlo (SMC) and Markov chain Monte Carlo (MCMC) methods provide computational tools for systematic inference and learning in complex dynamical systems, such as nonlinear and non-Gaussian state-space models. This thesis builds upon several methodological advances within these classes of Monte Carlo methods. READ MORE

  6. 4. Timing-Based Localization using Multipath Information

    Author : Andreas Bergström; Fredrik Gustafsson; Gustaf Hendeby; Fredrik Gunnarsson; Erik Leitinger; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The measurements of radio signals are commonly used for localization purposes where the goal is to determine the spatial position of one or multiple objects. In realistic scenarios, any transmitted radio signal will be affected by the environment through reflections, diffraction at edges and corners etc. READ MORE

  7. 5. Uplink Load in CDMA Cellular Systems

    Author : Erik Geijer Lundin; Fredrik Gunnarsson; Fredrik Gustafsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Code Division Multiple Access;

    Abstract : Cellular mobile systems designed to handle multimedia services are currently being developed. The primary goal for any mobile system is to provide a satisfactory quality of service, both to operators and customers. Providing good quality of service while maintaining system stability requires accurate knowledge of the system load. READ MORE
