  1. 1. Extraction of Loudspeaker- and room impulse responses under overlapping conditions

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Felix Gustafsson; [2022]
    Nyckelord :Signal processing; Optimization; Acoustics; Dereverberation; Sparse deconvolution; Multipath propagation;

    Sammanfattning : A loudspeaker is often considered to be a Linear Time Invariant (LTI) system, which can be completely categorized by its impulse response. What sets loudspeakers apart from other LTI-systems is the acoustical aspect including echoes, which makes it a lot harder to take accurate noise free measurements compared to other LTI-systems such as a simple RC circuit.

  3. 2. Deep Learning for Positioning with MUSIC

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Glädje Karl Olsson; [2021]
    Nyckelord :Positioning; Deep Learning; MUSIC; MUSIC-algorithm;

    Sammanfattning : Estimating an object’s position can be of great interest in several applications,and there exists many different methods to do so. One approach is with Directionof Arrival (DOA) measurements from receivers to use the triangulation techniqueto estimate one or more transmitter’s position. LÄS MER

  4. 3. Indoor Positioning Bluetooth Angle of Arrival

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Mohammed M T Amer; Khadeeja Gamal Mohammed Atteya; [2020]
    Nyckelord :Angle of Arrival; Bluetooth Low energy; Indoor positioning; Internet of Things; Bluetooth direction finding.; Technology and Engineering;

    Sammanfattning : In this thesis, we present the Angle of Arrival (AoA) technique to detect the direction of a source indoors using radio frequency (RF) signal. This technique estimates the direction of the incoming Bluetooth signal, using a tag as a transmitter and an array equipped with a number of antennas as a receiver. LÄS MER

  5. 4. A self-calibrating system for finger tracking using sound waves

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Linus Hammarlund; [2017]
    Nyckelord :cfrc; gcc-phat; srp-phat; self-calibration; toda; toa; Technology and Engineering; Mathematics and Statistics;

    Sammanfattning : In this thesis a system for tracking the fingers of a user using sound waves is developed. The proposed solution is to attach a small speaker to each finger and then have a number of microphones placed ad hoc around a computer monitor listening to the speakers. LÄS MER

  7. 5. Performance Assessment of Massive MIMO Systems for Positioning and Tracking of Vehicles in Open Highways

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Markus Petersson; [2017]
    Nyckelord :massive MIMO; MIMO; positioning; tracking;

    Sammanfattning : The next generation of mobile networks (5G) is currently being standardized, and massive MIMO (Multiple-Input-Multiple-Output) is a strong candidate to be part of this standard. Other than providing higher data rates and lower latency, high accuracy positioning is also required. LÄS MER
