2. 1. Moment Estimation Using Extreme Value Methods

   Author : Joachim Johansson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pareto distribution; mean estimation; heavy tailed distributions; telecommunication; m -dependence; superpopulation sampling; peaks over threshold; telecommunication;

   Abstract : The thesis is composed of three papers, all dealing with the application of extreme value methods to the problem of moment estimation for heavy-tailed distributions. In Paper A, an asymptotically normally distributed estimate for the expected value of a positive random variable with infinite variance is introduced. READ MORE

4. 2. Estimation of Speaker Age : Effects of Speech Properties and Speech Material

   Author : Sara Skoog Waller; Mårten Eriksson; Billy Jansson; Mittuniversitetet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Age estimation; Voice perception; Speech properties; Speech rate; Vocal disguise; Age disguise; Accuracy; Confidence; Spontaneous speech;

   Abstract : The aim of this thesis was to investigate factors related to accuracy in estimation of speaker age and the role of certain speech properties in perception and manipulation of speaker age, as well as their interaction with the speech material that the age estimates were based on. This thesis consists of three studies. READ MORE

5. 3. On the Mean Square Error of Transfer Function Estimates with Applications to Control

   Author : Svante Gunnarsson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mean square error; Transfer function; Estimation; Applications;

   Abstract : In this report we study the mean square error of transfer function estimates obtained by identification. The model quality is related to the use of models in regulator design, and the properties of affecting the bias part of the mean square error, both in fixed parameter control and adaptive control.

6. 4. Subspace-Based Parameter Estimation Problems in Signal Processing

   Author : Joakim Sorelius; Torsten Söderström; Peter Stoica; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor array processing; parameter estimation; spread spectrum communication; direct sequence CDMA; order estimation; subspace fitting; blind identification; system identification; Signal Processing; Signalbehandling;

   Abstract : The effects of multipath-induced angular spread and non-zero band-width on narrow-band direction-of-arrival (DOA) estimation are investigated. In both cases expressions for the resulting estimation error are developed for the MUSIC, ESPRIT and WSF DOA estimators. READ MORE

7. 5. Channel Estimation and Self-Interference Suppression for MIMO Relaying Systems

   Author : Panagiota Lioliou; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; estimation; expectation-maximization EM ; half-duplex; Bayesian; multiple-input multiple-output MIMO ; Cramer-Rao Bound CRB ; full-duplex; relays; performance analysis; Kalman filter KF ; self-interference.; Amplify-and-forward AF ; least squares LS ;

   Abstract : Recently, the introduction of relaying nodes in wireless channels has been identified as a promising technique for providing broader coverage, higher transmission rates, and increased reliability. Moreover, when the concept of relaying systems is combined with that of multiple-input multiple-output (MIMO) technology, thesystem performance can be further improved by exploiting the spatial dimension.
