  1. 1. Improving the Robustness of Over-the-Air Synchronization for 5G Networks in a Multipath Environment

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Anders Erninger; [2023]
    Nyckelord :Peak selection algorithms; Peak matching; Time alignment error; Over-the-air synchronization; Multipath environment; Toppvalsalgoritmer; Toppmatchning; Tidsfel; Luftburen synkronisation; Flervägsmiljö;

    Sammanfattning : Synchronization between base stations is a fundamental part of any operating telecommunication system. With 5G and future generations of mobile networks, the data speeds are getting higher, which creates the need for fast and accurate synchronization. In wireless systems, the transmitted signals are affected by the environment. LÄS MER

  3. 2. Data Analysis for Hearability and Synchronization in Telecom Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Sun Xin; [2022]
    Nyckelord :5G; Time Synchronization; Machine Learning; Deep Learning; 5G; Tidssynkronisering; Maskininlärning; Djupinlärning;

    Sammanfattning : In a wireless communication system, synchronization is one of the most critical functions. Good timing and synchronization can prevent messages of the communication system from interfering with each other and enable a smooth message transfer. LÄS MER

  4. 3. Impact of Time Synchronization Accuracy in Integrated Navigation Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hemanth Ram Kartik Bommakanti; [2019]
    Nyckelord :Real-Time Solution; Time Synchronization; Integrated Navigation System; Global Navigation Satellite System; Inertial Measurement Unit; Realtidslösning; tidssynkronisering; integrerat navigationssystem; globalt satellitbaserat navigationssystem; tröghetsmätningsenhet;

    Sammanfattning : Global Navigation Satellite System/Inertial Measurement Unit (GNSS/IMU) Integrated Navigation Systems (INS) integrate the positive features of GNSS and IMU for optimal navigation guidance in high accuracy outdoor navigation systems, for example using Extended Kalman Filter (EKF) techniques. Time synchronization of IMU data with precise GNSS based time is necessary to accurately synchronize the two systems. LÄS MER

  5. 4. A field study in Kenya of insolation parameters to make water drinkable in the household water treatment unit SOLVATTEN

    Kandidat-uppsats, Institutionen för teknikvetenskaper

    Författare :Hannah Lundström; Emil Hagström; [2012]
    Nyckelord :Solvatten; Kenya; Teknisk Fysik; MFS; Solar energy; Water cleaning;

    Sammanfattning : SOLVATTEN is a household water cleaning device that cleans water with solar energy using filtration, pasteurization and UV sterilization. A field study of the necessary amount of solar insolation that is required to make water drinkable has been carried out in Kenya using a new type of indicator developed by Solvatten AB. LÄS MER

  7. 5. Design of a parallel A/D converter system on PCB : For high-speed sampling and timing error correction

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik
