  1. 21. Acoustic echo cancellation inside a truck cabin

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Balaji Ramkumar; [2020]
    Nyckelord :Echo Cancellation; NLMS; Normalized Cross Correlation; Truck; Noise;

    Sammanfattning : In the modern world, a day without telecommunication is almost unimaginable. A telecommunication system is used in almost every sector. In earlier days only luxury cars had the feature of a hands free communication but now it has become one of the basic requirements in any segment of vehicles. LÄS MER

  3. 22. Investigation on Positioning Techniques for Indoor Office Scenario

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

    Författare :Yan Shu; Yujie Zhang; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This master thesis aims to investigate downlink positioning techniques and improve fifth-generation (5G) cellular positioning performance in the indoor office scenario. In the thesis work, we target in the indoor office scenario because it is a typical deployment scenario standardized in 3GPP release 16. LÄS MER

  4. 23. Optimizing multi-robot localization with Extended Kalman Filter feedback and collaborative laser scan matching

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Fredrik Ginsberg; [2020]
    Nyckelord :;

    Sammanfattning : Localization is a critical aspect of robots and their industrial applications, with its major impact on navigation and planning. The goal of this thesis is to improve multi-robot localization by utilizing scan matching algorithms to calculate a corrected pose estimate using the robots' shared laser scan data. LÄS MER

  5. 24. Blind Channel Equalization for Shortwave Digital Radio Communications

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Tomas Busk; [2020]
    Nyckelord :Blind Channel Equalization; Equalization; adaptive filter; radio communication; Blind kanalutjämning; kanalutjämning; adaptivt filter; radiokommunikation;

    Sammanfattning : In this thesis the concept of Blind Channel Equalization has been examined and algorithms suitable to blindly equalize the channel are presented and evaluated on simulated data. The concept of blind equalization is to equalize a communica- tions channel without relying on a training sequence or pilot tone, which may be either unknown to the receiver or not exist at all.

  7. 25. Finding the most suitable auxiliary sonar for terrain-aided navigation and behavior-fusion based obstacle avoidance for an autonomous underwater vehicle

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :NILAS OSTERMAN; [2019]
    Nyckelord :;

    Sammanfattning : Autonomous underwater vehicles are rapidly becoming more common and developed for both military as well as civilian applications such as; mine countermeasures or in the field of geoscience. One of the main issues these vehicles are facing today is the navigation capability. LÄS MER
