  4. 12. Computation of Parameters in some Mathematical Models

    Author : Gunilla Wikström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; inverse problems; parameter estimation; systems of ordinary differential equations; short-cut methods; separable nonlinear least squares problems; Matlab toolbox for nonlinear least squares ; linear systems of equations; pseudoinverse solution; perturbation theory; singular value decomposition; experimental error analysis; Computer science; Datavetenskap;

    Abstract : In computational science it is common to describe dynamic systems by mathematical models in forms of differential or integral equations. These models may contain parameters that have to be computed for the model to be complete. READ MORE

  5. 13. Estimation Using Low Rank Signal Models

    Author : Kaushik Mahata; Torsten Söderström; Mats Viberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parameter estimation; separable least squares; statistical analysis; viscoelasticity; subspace algorithms; spectrum estimation; Signal processing; Signalbehandling;

    Abstract : Designing estimators based on low rank signal models is a common practice in signal processing. Some of these estimators are designed to use a single low rank snapshot vector, while others employ multiple snapshots. This dissertation deals with both these cases in different contexts. READ MORE

  6. 14. Channel Estimation for Amplify and Forward Relay Networks

    Author : Panagiota Lioliou; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel estimation; relay networks; Multiple-input-multiple-output MIMO ; Cramer-Rao Lower Bound CRB .; least squares LS ;

    Abstract : The use of intermediate-relaying nodes has been identified as a promising technique for enhancing coverage and combating the impairments of Multiple-Input-Multiple-Output (MIMO) wireless channels. The main ideais to introduce relays that forward the data to the destination which isotherwise out of the reach of the source. READ MORE

  7. 15. On Parameter Estimation and Control of Time-Varying Stochastic Systems

    Author : Bengt Lindoff; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; Adaptive Predictive Control; Adaptive Stochastic Control; Dual Control; Convergence Analysis; Quadratic Forms; Forgetting Factor; Recursive Least Squares; Recursive Estimation; Linear Systems; Time-Varying Stochastic Systems; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Abstract : This thesis is about parameter estimation and control of time-varying stochastic systems. It can be divided into two parts. The first part deals with an estimation algorithm commonly used when estimating parameters in time-varying stochastic systems, the Recursive Least Squares (RLS) algorithm with forgetting factor.
