  1. 1. Examining the Effects of AWGN Jamming on a Tactical Data Link Communication System

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

    Författare :Noor Schroen; [2023]
    Nyckelord :Tactical Data Links; VOACAP; HF; AWGN; Jamming; Tactical Data Links; VOACAP; HF; AWGN; Jamming; Tactical Data Links; VOACAP; HF; AWGN; Jamming;

    Sammanfattning : This master thesis investigates the jamming of Tactical Data Links (TDLs). The goal is to make a model that is capable of giving an overview of a communication system under jamming conditions, offering the user a suggestion for the best coding scheme and modulation to use in any given situation.

  3. 2. Performance Analysis of STTC-Based MIMO Under Cognitive RadioScenarios

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Sanjana Kankantee; Sai Praneeth Reddy Ganta; [2023]
    Nyckelord :Space-time trellis coding; MIMO; Cognitive radio; Performance; Bit error rate; Diversity; AWGN; Rayleigh fading; Detection; Spectrum.;

    Sammanfattning : This thesis presents a comprehensive investigation into improving wireless transmission rates and reliability through the implementation of Space Time Trellis Codes(STTC). The study focuses on enhancing the coding gain, diversity gain, and flexible transmission capabilities, which are crucial for Error-Correcting Codes (ECC)in wireless communications. LÄS MER

  4. 3. Autonomous Landing of an Unmanned Aerial Vehicle on an Unmanned Ground Vehicle using Model Predictive Control

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Nyckelord :Model predictive control; MPC; Unmanned aerial vehicle; UAV; Unmanned ground vehicle; UGV; Path planning; Vehicle dynamics; Autonomous systems; Autonomous landing; Quadcopter; Gazebo; ROS;

    Sammanfattning : The research on autonomous vehicles, and more specifically cooperation between autonomous vehicles, has become a prominent research field during the last cou- ple of decades. One example is the combination of an unmanned aerial vehicle (UAV) together with an unmanned ground vehicle (UGV). LÄS MER

  5. 4. Importance Sampling in Wireless Communication Systems with Ultra-Low Error Rates

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

    Författare :Bharat Maheshwari; Yewen Zhou; [2022]
    Nyckelord :error region; Monte Carlo; importance sampling; rejection sampling; Kullback-Leibler divergence.; Technology and Engineering;

    Sammanfattning : Simulation mimics the behaviour of real world processes or the system over time. It helps us to understand the impact of modification and the effect of introducing various interventions to a system. LÄS MER

  7. 5. On the statistics and practical application of the reassignment method for Gabor spectrograms

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Erik. M Månsson; [2019]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The reassignment method is a technique for improving the concentration of signals in spectrograms and other time-frequency representations (TFR). It achieves this by displacing the points in a TFR according to the reassignment vector for every point. LÄS MER
