  1. 1. Energy-Efficient Fixed-Coefficient FIR Filters for Millimeter-Wave Radios

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Erik Lundell; Gustav Molin; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : With the introduction of millimeter-wave antenna arrays in 5G base-stations and ever-increasing data volumes, the power consumption of the signal processing in digital radio systems has increased over the last decade. This, combined with increased cost and environmental awareness, has put focus on power optimization. LÄS MER

  4. 3. Arbitrary motion Synthetic Aperture Radar

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Filip Alberius; Erik Rolander; [2023]
    Nyckelord :RADAR; SAR; Synthetic Aperture Radar; Pulsed Coherent Radar; PCR; VR; Virtual Reality; IMU; Inertial Measurment Unit; VAA; Virtual Antenna Array; Obstacle detection; Signal Processing; Matched Filter Method.; Technology and Engineering;

    Sammanfattning : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. LÄS MER

  5. 4. Quadcopter Control System Design and Implementation with LQR assisted by Kalman Filter: An Experimental Study

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Ludwig Horvath; Martin Petré; [2023]
    Nyckelord :;

    Sammanfattning : This study stems from the audacious assumption that two bachelor students could successfully construct a functional quadcopter from scratch, covering both software and hardware aspects. The project begins by establishing a foundation for modeling the quadcopter dynamics, including derivation and linearization techniques for implementing a linear quadratic regulator (LQR). LÄS MER

  7. 5. Formation Control of UAVs for Positioning and Tracking of a Moving Target

    Master-uppsats, Linköpings universitet/Fordonssystem
