  2. 6. A Software-Defined Baseband for Satellite Ground Operations : Feasibility and Design

    Author : Moses Browne Mwakyanjala; Jaap van de Beek; Élcio Jeronimo de Oliviera; Jaan Praks; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Software-Defined Radios; Satellite Ground Operations; Satellite Telemetry; Command; and Tracking; Onboard space systems; Rymdtekniska system;

    Abstract : Satellite telemetry, tracking, and command (TT&C) is a crucial activity needed to maintainthe health of a spacecraft or sometimes to facilitate payload data download. TT&Cground operations are facilitated by a communication device known in the TT&C communityas a baseband. READ MORE

  4. 7. Physical Layer Security Issues in Massive MIMO and GNSS

    Author : Ziya Gülgün; Erik G. Larsson; Panagiotis Papadimitratos; Hirley Alves; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Wireless communication technology has evolved rapidly during the last 20 years. Nowadays, there are huge networks providing communication infrastructures to not only people but also to machines, such as unmanned air and ground vehicles, cars, household appliances and so on.

  5. 8. Mobile Satellite Broadcast and Multichannel Communications : analysis and design

    Author : Cristoff Martin; Björn Ottersten; Jack Winters; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; communications; satellite broadcast; mobile; MIMO; asymptotic analysis; spatial multiplexing; Signalbehandling; Signal processing; Signalbehandling;

    Abstract : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. READ MORE

  6. 9. Dude, Where's My Car? Cellular Navigation for Autonomous Driving

    Author : Russ Whiton; Kommunikationsteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Position and direction estimation is useful for numerous engineering applications for commercial, scientific, and military purposes. Technology that fuses observations of signals broadcast by Global Navigational Satellite Systems (GNSS) with inertial measurements is standard for electronic devices, but this requires at least a periodically unobstructed view of the sky to perform reliably.

  7. 10. GNSS and Massive MIMO : Spoofing, Jamming and Robust Receiver Design for Impulsive Noise

    Author : Ziya Gülgün; Erik G. Larsson; Panos Papadimitratos; Sergiy A. Vorobyov; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this thesis, we focus on vulnerabilities and robustness of two wireless communication technologies: global navigation satellite system (GNSS), a technology that provides position-velocity-time information, and massive multiple-input-multiple-output (MIMO), a core cellular 5G technology. In particular, we investigate spoofing and jamming attacks to GNSS and massive MIMO, respectively, and the robust massive MIMO receiver against impulsive noises. READ MORE
