  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

  3. 2. Wave Propagation Experiment on FPGA with Miniaturized Payload for Sounding Rocket Application

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Leonardo Filippeschi; [2022]
    Nyckelord :Wave propagation experiment; REXUS BEXUS; FPGA; IQ demodulation; ADC; VHDL;

    Sammanfattning : This bachelor's thesis aims to implement a wave propagation experiment on Field-Programmable Gate Array to detect the signal strength at pre-defined frequencies for use in sounding rocket experiments. This includes the choice of suitable components such as analog to digital converters, filters, voltage regulators, and amplifiers. LÄS MER

  4. 3. The hydrodynamic impacts of Estuarine Oyster reefs, and the application of drone technology to this study

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Oskar Evert Johansson; [2021]
    Nyckelord :Geography; Geographical Information Systems; GIS; Physical Geography; Oyster Reef; Drone; UAV; Hydrodynamics; Earth and Environmental Sciences;

    Sammanfattning : The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. LÄS MER

  5. 4. PLL for 5G mmWave

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Daniel Bakic; Jinzhuo Wu; [2020]
    Nyckelord :PLL; 5G-NR; RFIC; beamforming; 22nm FDSOI; charge pump; vco; loop filter; frequency divider; phase detector; phase noise; jitter; Technology and Engineering;

    Sammanfattning : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. LÄS MER

  7. 5. Design and Development of a Measurement System to Track the Motion of a Point Absorber

    Master-uppsats,

    Författare :Juliana Lüer; [2020]
    Nyckelord :accelerometer; AHRS; battery; buoy; data transmission; GNSS; gyroscope; IMU; solar panel; wave energy;

    Sammanfattning : Because of climate change renewable energy field is becoming more and more relevant. Renewable energy can be gained from the sun, from wind but also from ocean waves. To support the research and development in this field reliably measured wave data is collected through a measurement system that shows the exact position of a buoy. LÄS MER
