  1. 1. 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

  3. 2. Software Defined VNA : Measure Coupling Between Elements in an Antenna Array

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Alexander Söderlund; [2023]
    Nyckelord :VNA; Vector Network Analyser; SDR; KrakenSDR; S-parameter; Antenna Coupling;

    Sammanfattning : With improvements in hardware of antenna receivers, fully digital arrays have been made possible to use in real time systems. These systems have a greater complexity, with the advantage of more dynamic system design since the use of the communication system can be changed with only a software change. LÄS MER

  4. 3. Direct Signal Interference Suppression and Target Detection for Low-Cost SDR-Based Passive Bistatic Radar

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Oskar Jonsson; [2022]
    Nyckelord :passive radar; ECA; LMS; software-defined radio;

    Sammanfattning : Passive radar is a technology for detection of targets using echoes of existing radio transmitter, such as FM-radio. Since only receivers are needed for operation, a passive radar system has the possibility of being implemented using low-cost hardware. LÄS MER

  5. 4. GNSS Safety and Handling

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

    Författare :Axel Björklund; [2022]
    Nyckelord :Navigation; GNSS; GPS; Galileo; OSNMA; TESLA protocol; SHA-256; jamming; spoofing; SDR; GPS-SDR-SIM; Smart Tachograph; dead reckoning; U-blox; Volvo Group; Volvo FH;

    Sammanfattning : Satellite navigation (such as GPS) has become widely successful and is used by billions of users daily. Accuratepositioning and timing has a wide range of applications and is increasingly being integrated in safety criticalsystems such as autonomous operations, traffic management, navigation for airplanes and other vehicles.

  7. 5. Polyphase Symbol Timing Synchronization on a Software-Defined Radio

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

    Författare :Georg Lundberg; [2021]
    Nyckelord :SDR; Software-Defined Radio; Polyphase; Symbol Timing Synchronization; Satellite Communication; MATLAB; Simulink; Xilinx; English;

    Sammanfattning : Software-defined radio is a continuously developing technology applied in fields of mobile communications and among others. It is a radio communication system where software is used to implement parts of its functionality in an embedded system or computer. LÄS MER
