  1. 1. Machine Learning Technique for Beam Management in 5G NR RAN at mmWave Frequencies

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

    Författare :Joel Bill; Gustav Fahlén; [2020]
    Nyckelord :Machine Learning; Reinforcement Learning; Beam Management; Beam Tracking; mmWaves; Technology and Engineering;

    Sammanfattning : Ericsson has an interest in investigating if the fast-growing concept known as machine learning can be applied to beam management, in a 5G NR environment using mmWave frequencies. Because of the high path-loss at mmWave frequencies and high throughput demands of 5G NR systems it is crucial to the UE to always stay connected to the most suitable beam, to provide highest possible throughput.

  2. 2. Lean Beam Management for New Radio

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

    Författare :Nawanit Kumar; [2020]
    Nyckelord :5G; NR; MIMO; Beam management; CSI-RS; Technology and Engineering;

    Sammanfattning : The use of millimetre-wave frequencies in Fifth generation New Radio has lead to high path loss due to radio propagation environment. Simultaneously, high data rates is a must for current products due to high market demand. This requirement accounts for efficient tracking of the best beam for the user equipment to stay connected to it. LÄS MER

  3. 3. Vibration analysis for predictive maintenance of a rotary pump. : Optimal accelerometer configuration based on vibration analysis for cavitation detection of a bi-winged positive displacement pump.

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

    Författare :Gustav Osswald; [2019]
    Nyckelord :;

    Sammanfattning : Predictive maintenance based on condition monitoring uses sensor and system data to prevent damage, in advance to a failure occurring, allowing for a service to be performed at an optimal position in time. Condition based predictive maintenance estimates time of system failure based on a priori information, which has shown to be much more cost effective than traditional maintenance methods. LÄS MER

  4. 4. Finding the most suitable auxiliary sonar for terrain-aided navigation and behavior-fusion based obstacle avoidance for an autonomous underwater vehicle

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

    Författare :NILAS OSTERMAN; [2019]
    Nyckelord :;

    Sammanfattning : Autonomous underwater vehicles are rapidly becoming more common and developed for both military as well as civilian applications such as; mine countermeasures or in the field of geoscience. One of the main issues these vehicles are facing today is the navigation capability. LÄS MER

  5. 5. Optimization of 5G New Radio for Fixed Wireless Access

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Jonathan Palm; [2019]
    Nyckelord :;

    Sammanfattning : With the advent of new 5G networks, the interest in connecting house-hold to the Internet via mobile networks has increased. One such way toconnect users is using completely stationary antennas. This use-case iscalled Fixed Wireless Access (FWA) and is seen as promising, cost-efficient means of expanding internet connectivity. LÄS MER
