  1. 1. Exploiting Sparse Structures in Source Localization and Tracking

    Författare :Maria Juhlin; Matematisk statistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Source localization; Cramér-Rao bounds; Convex Optimization;

    Sammanfattning : This thesis deals with the modeling of structured signals under different sparsity constraints. Many phenomena exhibit an inherent structure that may be exploited when setting up models, examples include audio waves, radar, sonar, and image objects. LÄS MER

    Sammanfattning : .... LÄS MER

  4. 3. Antennas, Wave Propagation, and Localization in Wireless Body Area Networks

    Författare :Rohit Chandra; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Body Area Network; WBAN; body sensor network; body-centric communication; wearable devices; ear-to-ear propagation; antennas; analytical propagation model; localization; wireless capsule endoscopy; in-mouth device; implants;

    Sammanfattning : A network of communicating wireless devices that are implantable, wearable or within close proximity of a human body is called wireless body area network (WBAN). The propagation channels for the devices in the WBAN are either through the body or over the body. LÄS MER

  5. 4. Sound source localization from laser vibrometry recordings

    Författare :Erik Olsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : Acoustic holography deals with a typical inverse problem, to obtain the unknown from something that is known. From measurements of sound, most often using microphone arrays, reconstructions of the sound field are made in an attempt to find out what causes the sound. LÄS MER

  7. 5. Direction of Arrival Estimation and Localization of Multiple Speech Sources in Enclosed Environments

    Författare :Mikael Swartling; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming; Detection and classification; Speech enhancement; Source localization;

    Sammanfattning : Speech communication is gaining in popularity in many different contexts as technology evolves. With the introduction of mobile electronic devices such as cell phones and laptops, and fixed electronic devices such as video and teleconferencing systems, more people are communicating which leads to an increasing demand for new services and better speech quality.
