  2. 1. Space-time processing and equalization for wireless communications

    Author : Erik Lindskog; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Space-time processing; channel estimation; equalization; maximum likelihood sequence estimation; decision feedback equalization; interference suppression; robustness; Materialvetenskap; Materials science; Teknisk materialvetenskap; Signal Processing; signalbehandling;

    Abstract : In this thesis several aspects of space-time processing and equalization for wire-less communications are treated. We discuss several different methods of improving estimates of space-time channels, such as temporal parametrization, spatial parametrization, reduced rank channel estimation, bootstrap channel estimation,and joint estimation of an FIR channel and an AR noise model.

  5. 3. Interference Rejection in Wireless Communication Systems

    Author : Anders Ranheim; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; direct-sequence spread spectrum; parameter estimation; multi-user detection; antenna array processing; iterative minimization; interference rejection; finite alphabet; order detection; signal structure; narrow-band interference;

    Abstract : This thesis is concerned with the problem of interference rejection in wireless communication systems. Different solutions are proposed, depending on the type of system under study and the amount of knowledge available about the signal and the propagation environment. READ MORE

  6. 4. Digital block transmission and time-of-flight estimation : receiver design and performance analysis

    Author : Håkan B. Eriksson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : This thesis is concerned with signal processing aspects of digital block transmission and time-of-flight estimation. Receivers are derived and analysed based on the assumption that the received signals have been corrupted with additive Gaussian noise and linear distortion. READ MORE

  7. 5. Order restricted inference over countable preordered sets. Statistical aspects of neutron detection

    Author : Vladimir Pastukhov; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Constrained inference; Isotonic regression; Density estimation; Grenander estimator; Limit distribution; Neutron detection;

    Abstract : This thesis consists of four papers. In the first paper, we study the isotonic regression estimator over a general countable preordered set. We obtain the limiting distribution of the estimator and study its properties. Also, it is shown that the isotonisation preserves the rate of convergence of the underlying estimator. READ MORE
