  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. Detecting and identifying radio jamming attacks in low-power wireless sensor networks

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

    Författare :John Kanwar; [2021]
    Nyckelord :;

    Sammanfattning : Wireless sensor networks (WSNs) are used in all kinds of different sectors ranging from agriculture, environment, healthcare and the military. Embedded systems such as sensor nodes are low-power and consist of low memory, which creates a challenge for its security. One of WSN’s worst enemies is interference radio jamming attacks. LÄS MER

  4. 3. Airborne Angle-Only Geolocalization

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Tove Kallin; [2021]
    Nyckelord :Angle-only; Bearing-only; Bearing; Geolocalization; Localization; Jammers; NLS; EKF; UKF; Cramér-Rao Lower Bound; Terrain; Elevation Data;

    Sammanfattning : Airborne angle-only geolocalization is the localization of objects on ground level from airborne vehicles (AV) using bearing measurements, namely azimuth and elevation. This thesis aims to introduce elevation data of the terrain to the airborne angle-only geolocalization problem and to demonstrate that it could be applicable for localization of jammers. LÄS MER

  5. 4. Methods for locating signal jammers with a UAV

    Master-uppsats, Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Andreas Höggren; Love Lindmark; [2018]
    Nyckelord :UAV; Signal jammer; RSSI; Signal reflection;

    Sammanfattning : Wireless communication today is a modern way to transport data from one location to another. One of the drawbacks of this feature is that a signal jammer can disrupt communications between the receiver and transmitter since the radio waves travel in the open air. This drawback can be exploited in both military and civilian applications. LÄS MER

  7. 5. Detection and Classification of Interference in Mobile Communication Systems

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Christoffer Ring; [2015]
    Nyckelord :GSM; Interference; Impulsiveness Ratio; USRP; GNU Radio;

    Sammanfattning : The usage of wireless technology has in the past decade vastly increased and it continues to do so as well. Because of this, we become more and more reliant on this considerably fragile technology. Wireless technology, which uses radio waves to transmit data from one point to another can easily be interfered by radio jammers. LÄS MER
