  1. 1. Implementation and Evaluation of Encoder Tools for Multi-Channel Audio

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Tomas Malmelöv; [2019]
    Nyckelord :Scene based audio; 3D audio; Spatial audio; Ambisonics; HOA; Multi-channel audio; Audio compression; MPEG-H;

    Sammanfattning : The increasing interest for immersive experiences in areas such as augmented and virtual reality makes high quality 3D sound more important than ever before. A technique for capturing and rendering 3D audio which has received more attention during the last twenty years are Higher Order Ambisonics (HOA). LÄS MER

  3. 2. Active Noise Control with Virtual Reference Signals in an FXLMS Algorithm

    Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

    Författare :Johan Nygren; [2018]
    Nyckelord :road noise; active noise control; FXLMS; virtual reference signals; vagbuller; aktiv bullerbekampning; FXLMS; virtuella referenssignaler;

    Sammanfattning : Noise pollution from road traffic is one of the greatest environmental issues in modern day, and the social cost for road traffic noise was estimated to over 16 billion SEK per year in Sweden in2014. Passive or active control methods can be used to reduce the noise. LÄS MER

  4. 3. Virtual Cycle-accurate Hardware and Software Co-simulation Platform for Cellular IoT

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

    Författare :Marcel Tovar Rascon; Patrik Elfborg; [2017]
    Nyckelord :co-simulation; cycle-accurate; ESL; HLS; SystemC; SoC Designer; IoT; SoC; FPGA; embedded; Technology and Engineering;

    Sammanfattning : Modern embedded development flows often depend on FPGA board usage for pre-ASIC system verification. The purpose of this project is to instead explore the usage of Electronic System Level (ESL) hardware-software co-simulation through the usage of ARM SoC Designer tool to create a virtual prototype of a cellular IoT modem and thereafter compare the benefits of including such a methodology into the early development cycle.

  5. 4. Wireless system design : NB-IoT downlink simulator

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

    Författare :Piotr Krasowski; Douglas Troha; [2017]
    Nyckelord :nb-iot; lte; lte-a; downlink; simulator; wireless;

    Sammanfattning : The newly defined NB-IoT standard currently lacks a toolkit and simulator. In order to develop algorithms for this new standard there is a need for channels and signals as reference during tests. MATLAB is commonly used for testing LTE signals and therefore the toolkit was developed in this environment. LÄS MER

  7. 5. Cylinder Pressure Sensor based Engine Combustion and Fuel System Diagnostics

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Michael Korres; [2016]
    Nyckelord :;

    Sammanfattning : Nowadays, the developed diagnostics models and software are not capable of locating the root cause of an emerging malfunction, or in other words the responsible component, while the vehicle is up and running. In most cases they are solely able to provide the driver with indications that a fault has been detected within a group of components. LÄS MER
