  1. 1. 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.

  3. 2. 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

  4. 3. 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.

  5. 4. Kommunikation mellan simulerad övning och utbildningsplattform

    Kandidat-uppsats, Lunds universitet/Högskoleingenjörsutbildning i datateknik

    Författare :Daniel Eckerström; Pierre Aupeix; [2017]
    Nyckelord :moodle; lms; xapi; tincan; scorm; akka; Technology and Engineering;

    Sammanfattning : The following bachelor thesis examines the possibility of using SCORM, xAPI or Moodle Web Service API as a communications channel between the learning management system Moodle and an existing training system delevoped by Saab. The aim is to use Moodle for storing users and their results while using Moodles built in funcionality for e-learning. LÄS MER

  7. 5. Development of Tool in MATLAB for the Durability Prediction of Radiators

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Akhil Mora; Raghavendra Machipeddi; [2017]
    Nyckelord :Basquin’s coeffcient; Cycle counting; Level Crossing; Thermal Cycling; Wöhler curve.;

    Sammanfattning : Durability is the most important factor in the design of heat-exchangers to meet the specifications of the customers. To predict the durability, endurance tests are carried out. In this thesis, one of the endurance tests, thermal cycling is performed for three different internal coolant flows until failure which is known as Wöhler test. LÄS MER
