  1. 1. Channel Estimation and Power Control Algorithms in the Presence of Channel Aging

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yan Bixing; [2023]
    Keywords : Fading channel; auto-regressive model; power allocation; uncrewed aerial vehicle networks; Fading kanal; auto-regressiv modell; krafttilldelning; obemannade flygfordonsnätverk;

    Abstract : Power allocation algorithms that determine how much power should be allocated to pilot and data symbols play an important role in addressing the trade-off between accurate channel estimation and high high spectral efficiency for data symbols in the presence of time-varying fading channels. Dealing with this trade-off is highly non-trivial when the channel changes or ages rapidly in time. READ MORE

    Abstract : Autonomous driving technology has the potential to revolutionize the way we think about transportation and its impact on society. Perceiving the environment is a key aspect of autonomous driving, which involves multiple computer vision tasks. READ MORE

  4. 3. Lithium-ion battery modeling and SoC estimation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ruoyu Xu; [2023]
    Keywords : lithium-ion battery; cell modeling; state of charge; extended Kalman filter; pack modeling; litiumjonbatteri; cellmodellering; laddningstillstånd; utökat Kalmanfilter; packmodellering;

    Abstract : The energy crisis and environmental pollution have become increasingly prominent in recent years. Lithium batteries have attracted extensive attention due to their high energy density, safety, and low pollution. To further study how the battery works, it is necessary to establish an accurate model conforming to the battery characteristics. READ MORE

  5. 4. Measurement-based WCET estimation in multicore real-time systems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Sören Meinken; [2022]
    Keywords : ;

    Abstract : Increasing complexity and advancements of hardware continue to make WCET analysis a non-trivial problem especially on modern COTS processors. Finding a tightand reliable WCET upper bound is vital for schedulability analysis and increasing theresource utilization of a real-time system. READ MORE

  6. 5. A Positioning System for Landing a UAV on a UGV in a GNSS-Denied Scenario

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Tim Wiik; [2022]
    Keywords : Sensor fusion; UAV; UGV; NIR-LED; Extended kalman filter; Unmanned Aerial Vehicle; Unmanned Ground Vehicle; Autonomous Landing; GNSS-denied Scenario;

    Abstract : A system of an unmanned aerial vehicle (UAV) collaborating with an unmanned ground vehicle (UGV) for use in for example surveillance, reconnaissance, transport and target acquisition is studied. The project investigates the problem of estimating the relative position, velocity and orientation between the UAV and the UGV required to autonomously land the UAV on the UGV during movement.
