  1. 1. Grafisk återgivning av radardetektion av flygplan : Utveckling av ett grafiskt användargränssnitt för PCL- och ADS-B-system

    Kandidat-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Alice Jansson; [2024]
    Nyckelord :GUI; Graphical user interface; PCL; Passive Coherent Location; ADS-B; HCI; Human-computer Interaction; Electronic warfare; Grafiskt användargränssnitt; MMI; Människa-maskin-interaktion; PCL; Passiv radar; ADS-B; Ljudkrig;

    Sammanfattning : Passive Coherent Location (PCL), eller Passiv Radar som det populärt kallas, är enteknologi inom radarlära som innefattar radartyper som inte själva skickar ut elektromagnetiska vågor för att finna och undersöka ett mål. Istället använder sig dessa radartyper av befintliga signaler, såsom radio- och TV-sändningar för att detektera mål. LÄS MER

  3. 2. Integrated Sensing and Communicationusing OFDM and Stepped FMCWSignals : Proof-of-Concept and Evaluation with Software DefinedRadios

    Master-uppsats, Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Författare :Sai Chetan Poluri; Tejaswi Dunuka; [2023]
    Nyckelord :5G and 6G Communications; FMCW; GNU Radio; ISAC; OFDM; SDR; Sensing; JSAC;

    Sammanfattning : The thesis work shows the implementation of sensing and communication, so a basic knowledge of analog and digital communication systems is needed to understand this paper Background. With the increase in smart devices, the bandwidth requirements are increased, which created congestion in the radio spectrum resources. LÄS MER

  4. 3. AI Based Methods for Matrix Multiplication in High Resolution Simulations of Radio Access Networks

    Master-uppsats, KTH/Matematisk statistik

    Författare :Marcus Johnson; Herman Forslund; [2023]
    Nyckelord :Product-Quantization; MADDNESS; Radio Access Networks; Channel Estimation; MIMO; Approximate Matrix Multiplication; Pruduktkvantisering; MADDNESS; RAN; MIMO; Approximativa matrismultiplikation;

    Sammanfattning : The increasing demand for mobile data has placed significant strain on radio access networks (RANs), leading to a continuous need for increased network capacity. In keeping with that, a significant advancement in modern RANs is the ability to utilize several receivers and transmitters, to allow for beamforming. LÄS MER

  5. 4. Improvement of simulation software for test equipment used in radio design and development

    Kandidat-uppsats, Linköpings universitet/Databas och informationsteknik

    Författare :Vincent Ahlström; [2023]
    Nyckelord :Python; Simulation; PyVISA-sim; Git; GitHub; Open Source;

    Sammanfattning : The global engineering design house Syntronic has requested a further development of the open source Python framework PyVISA-sim to enable dynamic simulations of signals and measuring instruments which would streamline development of their internal radio equipment testing tool. This tool is used by a world leading telecommunications company when developing their next generation radio equipment. LÄS MER

  7. 5. Utilizing Neural Networks To Adaptively Demodulate And Decode Signals In An Impulsive Environment

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för datalogi

    Författare :Andreas Andersson; [2023]
    Nyckelord :Neural Network; Demodulation; Decoding; Impulsive Noise; Alpha-stable Noise;

    Sammanfattning : Electromagnetic disturbance can be detrimental to the performance of a radio communication system, and in today’s society where more and more electronic devices are present in our everyday life it is increasingly vital to consider man-made interference. A communication system can take into consideration the noise characteristics and by doing so will excel in such areas, however, this follows that the algorithms utilized in such systems are more computationally complex and are therefore slow.
