  2. 6. Studies on Design and Implementation of Low-Complexity Digital Filters

    Author : Henrik Ohlsson; Lars Wanhammar; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-complexity digital filters; lattice wave digital filters LWDFs ; digital down converter DDC ; analog-to-digital converters ADCs ; Signal processing; Signalbehandling;

    Abstract : In this thesis we discuss design and implementation of low-complexity digital filters. Digital filters are key components in most digital signal processing (DSP) systems and are, for example, used for interpolation and decimation. READ MORE

    Author : Jonas Lundbäck; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vector sensors; Statistical signal processing; Antennas; Directional Coupler; Tranmission lines; Partial discharge;

    Abstract : This doctoral thesis is comprised of five parts. The first three parts concern signal processing and electromagnetic modelling of multiport antennas. The last two parts concern signal processing and transmission line theory applied to wave splitting on transmission lines. READ MORE

  5. 8. Parameter Estimation and Waveform Fitting for Narrowband Signals

    Author : Tomas Andersson; Peter Händel; István Kollár; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling; Signal processing; Signalbehandling;

    Abstract : Frequency estimation has been studied for a large number of years. One reason for this is that the problem is easy to understand, but difficult to solve. Another reason, for sure, is the large number of applications that involve frequency estimation, e. READ MORE

  6. 9. Implementation and Evaluation of Signal Processing Circuits for Optical Communication

    Author : Erik Börjeson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive Equalization; Carrier Phase Recovery; Digital Signal Processing; Application-Specific Integrated Circuits; Communication Systems; Fiber-Optic Communication;

    Abstract : The digital signal processing (DSP) circuits used in the fiber-optic communication links that make up the backbone of the Internet can be a significant contributor the over-all power dissipation of a link. As the number of connected users and their bandwidth requirements are expected to continue to grow over the coming years, the development of power-efficient high-throughput DSP systems is a critical factor in enabling this growth.

  7. 10. Modulation and channel effects in digital communication

    Author : Sara Sandberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : This thesis investigates three possible methods to increase the performance of digital communication systems, with focus on wireless systems, by accounting for some of the channel effects that may occur. The modulation scheme plays an important role in the impact of different channel effects on system performance and this work considers both a single-carrier system and orthogonal frequency-division multiplexing (OFDM).
