    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; optimal detection; transient signals; noncoherent detection; unknown arrival time; ultrasonic nondestructive testing; nonlinear sensor; stochastic resonance; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

    Abstract : This thesis is concerned with detection of transient signal families and detectors in nonlinear static sensor systems. The detection problems are treated within the framework of likelihood ratio based binary hypothesis testing. READ MORE

  5. 3. Wireless Sensor Network Positioning Techniques

    Author : Mohammad Reza Gholami; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; outer-approximations; Cram; Wireless sensor network; nonlinear and linear least squares; cooperative positioning; projection onto convex sets; maximum likelihood esti- mator;

    Abstract : Position information is one of the key requirements for wireless sensor networks(WSNs). Since GPS receivers have drawbacks when used in low-power sensor nodes,mainly due to latency in position recovery and limited access to GPS satellites in indoor-type scenarios, extracting the position information by means of the network itself, so-called positioning or localization, has been considered an eective solution for the posi-tioning problem.

  6. 4. Estimation of Nonlinear Dynamic Systems : Theory and Applications

    Author : Thomas B. Schön; Fredrik Gustafsson; Simon Godsill; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear estimation; system identification; Kalman filter; particle filter; marginalized particle filter; expectation maximization; automotive applications; Automatic control; Reglerteknik;

    Abstract : This thesis deals with estimation of states and parameters in nonlinear and non-Gaussian dynamic systems. Sequential Monte Carlo methods are mainly used to this end. These methods rely on models of the underlying system, motivating some developments of the model concept. READ MORE
