  2. 1. Digital signal processing methods and algorithms for audio conferencing systems

    Author : Fredric Lindström; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Audio conferencing systems;

    Abstract : Today, we are interconnected almost all over the planet. Large multinational companies operate worldwide, but also an increasing number of small and medium sized companies do business overseas. As people travel to meet and do businesses, the already exposed earth is subject to even more strain. READ MORE

  4. 2. Structure-Exploiting Numerical Algorithms for Optimal Control

    Author : Isak Nielsen; Daniel Axehill; Anders Hansson; Eric Kerrigan; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical Optimal Control; Model Predictive Control; Riccati Recursion; Parallel Algorithms; Low-Rank Modifications; Parametric Programming; Optimization; Explicit MPC; Moving Horizon Estimation; Partial Condensing;

    Abstract : Numerical algorithms for efficiently solving optimal control problems are important for commonly used advanced control strategies, such as model predictive control (MPC), but can also be useful for advanced estimation techniques, such as moving horizon estimation (MHE). In MPC, the control input is computed by solving a constrained finite-time optimal control (CFTOC) problem on-line, and in MHE the estimated states are obtained by solving an optimization problem that often can be formulated as a CFTOC problem.

  5. 3. Implementation of digit-serial filters

    Author : Magnus Karlsson; Mark Vesterbacka; Lars Wanhammar; Wlodek Kulesza; Viktor Öwall; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Implementation; CMOS; Low Power; High Speed; Wave Digital Filter WDF ; FIR filter; Signal processing; Signalbehandling;

    Abstract : In this thesis we discuss the design and implementation of Digital Signal Processing (DSP) applications in a standard digital CMOS technology. The aim is to fulfill a throughput requirement with lowest possible power consumption. READ MORE

  6. 4. Models and Methods for Development of DSP Applications on Manycore Processors

    Author : Jerker Bengtsson; Bertil Svensson; Shuvra S. Bhattacharyya; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; parallel processing; manycore processors; high-performance digital signal processing; dataflow; concurrent models of computation; parallel code mapping; parallel machine model; dynamic performance analysis; Computer engineering; Datorteknik;

    Abstract : Advanced digital signal processing systems require specialized high-performance embedded computer architectures. The term high-performance translates to large amounts of data and computations per time unit. The term embedded further implies requirements on physical size and power efficiency. READ MORE

  7. 5. Fast Radon Transforms and Reconstruction Techniques in Seismology

    Author : Viktor Nikitin; Matematik LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fourier transform FFT ; Radon transforms; GPU;

    Abstract : The measurements conducted in tomography and seismology typically yield large multidimensional data sets. This in combination with the fact that the data may have an irregular structure makes it computationally prohibitive to use simple reconstruction methods directly. READ MORE
