  2. 1. Filter Bank Design for Subband Adaptive Filtering

    Author : Jan Mark de Haan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Filter Bank Design; Subband Adaptive Filtering;

    Abstract : Adaptive filtering is an important subject in the field of signal processing and has numerous applications in fields such as speech processing and communications. Examples in speech processing include speech enhancement, echo- and interference- cancellation, and speech coding. READ MORE

  4. 2. Filter bank design for digital speech signal processing : methods and applications

    Author : Jan Mark de Haan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive filter theory; Subband filter banks;

    Abstract : Adaptive filter theory is an important subject in the field of signal processing and has numerous applications in speech processing, telecommunications and mechanical engineering. Examples in speech processing include suppression of background noise, echo cancellation and dereverberation (acoustic path equalization). READ MORE

  5. 3. Contributions to low-complexity maximally decimated filter banks

    Author : Linnea Rosenbaum; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Filter banks are systems of several filters with a common input or a common output. They are used whenever a signal needs to be split up into different frequency bands. The first filter banks were introduced in the seventies, and about ten years later it was shown how to design filter banks which do not introduce any errors to the signal. READ MORE

  6. 4. Performance and Implementation Aspects of Nonlinear Filtering

    Author : Gustaf Hendeby; Fredrik Gustafsson; Petar Djurić; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle filtering; nonlinear filtering; fault detection; Cramer-Rao lower bound; Kullback divergence; intrinsic accuracy; Automatic control; Reglerteknik;

    Abstract : I många fall är det viktigt att kunna få ut så mycket och så bra information som möjligt ur tillgängliga mätningar. Att utvinna information om till exempel position och hastighet hos ett flygplan kallas för filtrering. I det här fallet är positionen och hastigheten exempel på tillstånd hos flygplanet, som i sin tur är ett system. READ MORE

  7. 5. Subband Beamforming for Speech Enhancement within a Motorcycle helmet

    Author : Per Cornelius; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamfroming; Microphone array system;

    Abstract : The increased mobility in society has led to a need for convenient mobile communication in many different type of environments. Environments such as a motorcycle helmet, engine rooms and most industrial sites share a common challenge in that they often offer significant acoustic background noise. READ MORE
