  2. 11. Spectral Analysis of Nonuniformly Sampled Data and Applications

    Author : Prabhu Babu; Peter Stoica; Fredrik Gustafsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spectral analysis; array processing; nonuniform sampling; sparse parameter estimation; direction of arrival DOA estimation; covariance fitting; sinusoidal parameter estimation; maximum-likelihood; non-parametric approach; exoplanet detection; radial velocity technique; Sudoku; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Abstract : Signal acquisition, signal reconstruction and analysis of spectrum of the signal are the three most important steps in signal processing and they are found in almost all of the modern day hardware. In most of the signal processing hardware, the signal of interest is sampled at uniform intervals satisfying some conditions like Nyquist rate. READ MORE

  4. 12. Channel Estimation in Wireless Communication Systems Employing Multiple Antennas

    Author : Mikael Coldrey; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple antennas; capacity; channel estimation; non-parametric estimation; training; distributed sources; MIMO; Wireless communications; superimposed pilots; performance bounds;

    Abstract : Antennas that are able to adaptively direct the transmitted (and received) energy are of great interest in future wireless communication systems. The directivity implies reduced transmit power and interference, and also a potential for increased capacity. READ MORE

  5. 13. Data Driven Visual Recognition

    Author : Omid Aghazadeh; Stefan Carlsson; Jiri Matas; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Visual Recognition; Data Driven; Supervised Learning; Mixture Models; Non-Parametric Models; Category Recognition; Novelty Detection;

    Abstract : This thesis is mostly about supervised visual recognition problems. Based on a general definition of categories, the contents are divided into two parts: one which models categories and one which is not category based. We are interested in data driven solutions for both kinds of problems. READ MORE

  7. 15. Modelling transport, accessibility and productivity in Öresund

    Author : Tom Petersen; KTH; []
    Keywords : infrastructure assessment; regional consequences; validation; microlevel panel data; non-parametric method;

    Abstract : This licentiate thesis is about the provision of transportinfrastructure and the regional impacts of such provision.Three different techniques have been investigated that can beused for the assessment and forecasting of the effects ofinfrastructure: transport demand models and parametric andnon-parametric econometric estimation techniques.
