  1. 1. Contribution to the Understanding of the Effects of Propagation through the Ionosphere of P-band SAR Data

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Johannes Samuel Erland Rönner; [2023]
    Nyckelord :Synthetic aperture radar; Ionosphere;

    Sammanfattning : The BIOMASS mission from the European Space Agency (ESA) is designed to measurebiomass and carbon content in Earth’s forests. To account for phase changes caused byionospheric variations, a map-drift autofocus algorithm is developed, which utilises a phasescreen of the ionosphere to eliminate phase errors in the signal.

  3. 2. Development of GNSS Type Processing for the Characterization of the Mobile Propagation Channel

    Master-uppsats, KTH/Fastigheter och byggande

    Författare :Adrien Bardou; [2021]
    Nyckelord :LMS Channel; Multi-paths; GNSS; SCHUN; Simulation; LMS-kanal; flerv¨agar; GNSS; SCHUN; Simulering;

    Sammanfattning : Mobile communication systems are undergoing significant development on increasingly wide frequency bands (5G in particular). To support this development, a detailed characterization of the propagation of electromagnetic waves in L, S and C band between a station (satellite, airborne or ground) and a mobile platform is necessary to analyze and model the phenomena that have a decisive impact on the performance, availability and operability of systems.

  4. 3. A Blind Constellation Agnostic VAE Channel Equalizer and Non Data-Assisted Synchronization

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

    Författare :Fredrik Reinholdsen; [2021]
    Nyckelord :Blind; Equalization; Machine Learning; Variational; Autoencoder; VAE; Constellation; Agnostic; Synchronization; Neural; Networks;

    Sammanfattning : High performance and high bandwidth wireless digital communication underlies much of modern society. Due to its high value to society, new and improved digital communication technologies, allowing even higher speeds, better coverage, and lower latency are constantly being developed. LÄS MER

  5. 4. Analysis of comparative filter algorithm effect on an IMU

    Kandidat-uppsats,

    Författare :Johan Åkerblom Svensson; Joakim Gullberg Carlsson; [2021]
    Nyckelord :IMU; Vibration; autonomous driving; complementary filter; accelerometer; gyroscope;

    Sammanfattning : An IMU is a sensor with many differing use cases, it makes use of an accelerometer, gyroscope and sometimes a magnetometer. One of the biggest problems with IMU sensors is the effect vibrations can have on their data. The reason for this study is to find a solution to this problem by filtering the data. LÄS MER

  7. 5. Implementation of adaptive filtering algorithms for noise cancellation

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Författare :Tanja Lampl; [2020]
    Nyckelord :;

    Sammanfattning : This paper deals with the implementation and performance evaluation of adaptive filtering algorithms for noise cancellation without reference signal. Noise cancellation is a technique of estimating a desired signal from a noise-corrupted observation. LÄS MER
