   Author : Mikael Coldrey; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacity; Wireless communications; performance bounds; distributed sources; generalized beamforming; channel estimation; MIMO; training;

   Abstract : The focus of this thesis is on channel estimation in wireless communication systems that employ multiple antennas.The thesis is divided into two parts, whereof the first part addresses theproblem of parameter estimation of distributed sources. Due to, e.g. READ MORE

4. 7. Maximum spacing methods and limit theorems for statistics based on spacings

   Author : Magnus Ekström; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Estimation; spacings; maximum spacing method; consistency; ^-divergence; goodness of fit; unimodal density; entropy estimation; uniform distribution;

   Abstract : The maximum spacing (MSP) method, introduced by Cheng and Amin (1983) and independently by Ranneby (1984), is a general estimation method for continuous univariate distributions. The MSP method, which is closely related to the maximum likelihood (ML) method, can be derived from an approximation based on simple spacings of the Kullback-Leibler information. READ MORE

5. 8. Estimation of torque in heavy duty vehicles with focus on sensor hysteresis

   Author : Marcus Hedegärd; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hysteresis modelling; adaptive hysteresis compensation; hysteresis compensation; magnetoelastic torque sensor; Preisach model; generalized Prandtl-Ishlinskii model; cylinder pressure estimation; torque estimation;

   Abstract : For diagnosis and feedback control of vehicle powertrains, it is highly desired to monitor the torques at different locations online. The most obvious way to do this is to measure cylinder pressures, from which cylinder individual delivered torques can be calculated, or to use torque sensors. READ MORE

6. 9. Fundamental Estimation and Detection Limits in Linear Non-Gaussian Systems

   Author : Gustaf Hendeby; Fredrik Gustafsson; Niclas Bergman; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Estimation; Detection; Linear systems; Non-Gaussian; Limits; GLR; CRLB; Automatic control; Reglerteknik;

   Abstract : Many methods used for estimation and detection consider only the mean and variance of the involved noise instead of the full noise descriptions. One reason for this is that the mathematics is often considerably simplified this way. READ MORE

7. 10. On Detection and Estimation of Multiple Sources in Radar Array Processing

   Author : Jonny Eriksson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spatially correlated noise; Cramer-Rao bounds; estimation; feature reduction; virtual uniform linear arrays; classification; adaptive data reduction; nonlinear weighted least squares; multiple targets; detection;

   Abstract : This thesis deals with detection and estimation problems in sensor array signal processing. We treat the multiple hypothesis problem for complex sinusoids observed in spatially colored noise. READ MORE
