  2. 1. Generalized Bandpass Sampling Receivers for Software Defined Radio

    Author : Yi-Ran Sun; Svante Signell; Markku K. Renfors; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radio receivers; Software Defined Radio SDR ; uniform nonuniform sampling; reconstruction; bandpass sampling; noise aliasing; sampling jitter; generalized bandpass sampling; complex signal processing; complex FIR and IIR filter design; Switched-Capacitor SC circuit; Electrical engineering; Elektroteknik;

    Abstract : Based on different sampling theorem, for example classic Shannon’s sampling theorem and Papoulis’ generalized sampling theorem, signals are processed by the sampling devices without loss of information. As an interface between radio receiver front-ends and digital signal processing blocks, sampling devices play a dominant role in digital radio communications. READ MORE

  4. 2. Non-Uniform Sampling in Statistical Signal Processing

    Author : Frida Eng; Fredrik Gustafsson; Paulo Ferreira; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; signal processing; sampling; stochastic analysis; frequency transform; Automatic control; Reglerteknik;

    Abstract : Non-uniform sampling comes natural in many applications, due to for example imperfect sensors, mismatched clocks or event-triggered phenomena. Examples can be found in automotive industry and data communication as well as medicine and astronomy. READ MORE

  5. 3. Modeling and Control of Voltage Source Converters Connected to the Grid

    Author : Michael Lindgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; voltage source converter; switching frequency; pulse width modulation; IGBT valve; power electronics; small-signal; L-filter; LCL-filter; transfer function; line filter; active filtering; frequency response; sampling frequency;

    Abstract : This thesis deals with the modeling and control of pulse width modulated (PWM) voltage source converters connected to the grid. When voltage source converters are connected to the grid, the power quality and the dynamic performance are affected by the line filter connected between the converter and the grid, and by nonlinearities caused by the switching converter.

  6. 4. Frequency Domain Identification of Continuous-Time Systems : Reconstruction and Robustness

    Author : Jonas Gillberg; Lennart Ljung; Fredrik Gustafsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete-time domain; Frequency-domain identification; Signal processing; Frequency-domain; Automatic control; Reglerteknik;

    Abstract : Approaching parameter estimation from the discrete-time domain is the dominating paradigm in system identification. Identification of continuous-time models on the other hand is motivated by the fact that modelling of physical systems often take place in continuous-time. READ MORE
