  1. 1. Kalman Filters for Nonlinear Systems and Heavy-Tailed Noise

    Författare :Michael Roth; Fredrik Gustafsson; Simo Särkkä; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis is on filtering in state space models. First, we examine approximate Kalman filters for nonlinear systems, where the optimal Bayesian filtering recursions cannot be solved exactly. These algorithms rely on the computation of certain expected values. LÄS MER

  3. 2. Design Aspects of Coordinated Multipoint Transmission : A Study of Channel Predictions, Resource Allocation, User Grouping and Robust Linear Precoding for Coherent Joint Transmission

    Författare :Rikke Apelfröjd; Mikael Sternad; Anders Ahlén; Antti Tölli; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network MIMO; Centralized CoMP; Robust beamforming with imperfect CSI; Limited backhaul; Linear predictions of OFDM channels; Kalman filters; Predictor antennas; Long term channel prediction; Local resource allocation and user grouping; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Sammanfattning : Shadowed areas and interference at cell borders pose great challenges for future wireless broadband systems. Coordinated Multipoint (CoMP) coherent joint transmission has shown the potential to overcome these challenges by turning harmful interference into useful signal power. LÄS MER

  7. 5. Toward Sequential Data Assimilation for NWP Models Using Kalman Filter Tools

    Författare :Jelena Bojarova; Rolf Sundberg; Krzysztof Podgorski; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-Gaussian state space models; Kalman filtering; ETKF; 3D-Var; data assimilation; NWP; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Sammanfattning : The aim of the meteorological data assimilation is to provide an initial field for Numerical Weather Prediction (NWP) and to sequentially update the knowledge about it using available observations. Kalman filtering is a robust technique for the sequential estimation of the unobservable model state based on the linear regression concept. LÄS MER
