2. 1. Discerning the Receiver : A learning study with inexperienced writers aged 14-16

   Author : Britta Larsson Lindberg; Ulla Runesson Kempe; Anette Svensson; Jönköping University; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; writing instruction; writing; second language writing; dyslexia; inclusion;

   Abstract : The overall aim of the present study is to develop knowledge of Swedish students’ writing in English, and how teaching of a specific kind of writing can be designed and enacted. The study focuses on what the students need to discern in order to develop a more differentiated knowledge of how to adapt a message to an unknown receiver—in this case a message for a person at a hotel.

4. 2. Iterative receivers with channel estimation for MIMO and multi-user OFDM systems

   Author : Peter Hammarberg; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Iterative receiver; channel estimation; multi-user detection; OFDM; MIMO; IDMA; complexity; EXIT chart; channel measurements.;

   Abstract : The traffic in wireless networks has been showing an exponential growth over the last decade. In order to meet the demand, and support a continuation of this growth, the scarce radio resources need to be efficiently used. READ MORE

5. 3. On Receiver Algorithms for OFDM Systems

   Author : Florent Munier; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quantisation; multicarrier modulation; Intercarrier Interference ICI ; Phase noise; Wiener process; orthogonal frequency division multiplexing OFDM ; estimation; fading channels; channel estimation; iterative decoding.;

   Abstract : This thesis addresses the problem of designing a receiver for an Orthogonal FrequencyDivisionMultiplexing (OFDM)communication system operating over fading channels, taking into account the effects of hardware imperfections. We discuss solutions for efficiently estimating the parameters of a channel model and for compensating oscillator phase noise and analog to digital converter (ADC) quantisation errors at the receiver.

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. Efficient Electromagnetic Induction Modelling : Adaptive mesh optimisation, advanced boundary methods and iterative solution techniques

   Author : Laura M. Buntin; Thomas Kalscheuer; Gunilla Kreiss; Zhengyong Ren; Klaus Spitzer; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied geophysics; Electromagnetic theory; Numerical Modelling; Geo-Electromagnetics; Magnetotellurics; Controlled-source electromagnetics; Goal-oriented adaptive mesh refinement; Perfectly-matched layers; Iterative solution methods; Preconditioning; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

   Abstract : Forward modelling of electromagnetic induction data simulates the electric and magnetic fields within a computational domain for a given distribution of electromagnetic material properties and a given source of the electromagnetic field. The quantities of interest are the fields at receiver locations at the Earth's surface. READ MORE
