  1. 11. Exploring an extension of the operational design domain of a connected autonomous vehicle using a camera based positioning system

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

    Author : Albert Gunneström; [2021]
    Keywords : 5G; Autonomous vehicle; Off-board sensors; Positioning system; 5G; Autonoma fordon; Externa sensorer; Positioneringssystem;

    Abstract : Autonomous vehicles rely on perceiving the environment using on-board sensor. These sensors have inherent limitations in terms of their effective range and risk occlusion due to their placement in the environment. These constraints limit the operational design domain of autonomous vehicles due to reliability and safety concerns. READ MORE

  3. 12. Using a denoising autoencoder for localization : Denoising cellular-based wireless localization data

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

    Author : Alexander Danielsson; Edvard von Pfaler; [2021]
    Keywords : Autoencoder; Noise reduction; Neural network; Denoising autoencoder; Positioning data; Autoencoder; Brusreducering; Neurala nätverk; Brusreducerande autoencoder;

    Abstract : A denoising autoencoder is a type of neural network which excels at removingnoise from noisy input data. In this project, a denoising autoencoder isoptimized for removing noise from mobile positioning data. The mobilepositioning data with noise is generated specifically for this project. READ MORE

  4. 13. Hybrid Positioning Solution Using 5G and GNSS

    University essay from Linköpings universitet/Reglerteknik

    Author : Carl Rydholm; William Pommer; [2021]
    Keywords : 5G; Positioning; GNSS; Sensor Fusion; Signal Processing;

    Abstract : The importance of accurate position estimation is becoming more necessary as industries and society increasingly rely on autonomous or wireless devices while the capabilities of existing positioning solutions fail to meet the demanding requirements. This situation has provided opportunities for wireless positioning techniques with the rollout of 5G which has led to many enhancements to the network protocol related to positioning. READ MORE

  5. 14. M-MIMO Map Based Positioning in Wireless Networks

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

    Author : Zitong Xu; [2021]
    Keywords : Massive MIMO; Positioning; AoA; Wireless Networks; MATLAB; Massiv MIMO; Positionering; AoA; Trådlösa Nätverk; MATLAB;

    Abstract : The next generation 5G systems has attracted more and more attention to the rapid development of information and communication technology (ICT). Positioning is an important research area in 5G mobile networks, especially in M-MIMO wireless networks. READ MORE

  6. 15. Evaluation of Bluetooth 5.1 as an Indoor Positioning System

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Philip Andersson; Linus Persson; [2020]
    Keywords : Indoor Positioning System; AoA; RSSI; IMU; Sensor Fusion; Multipath Propagation; Inomhus positioneringssystem; AoA; RSSI; IMU; Sensor Fusion; Flervägsutbredning;

    Abstract : There is a high demand for Indoor Positioning Systems (IPS) due to the wide application possibilities. The main issue for localization by wireless signals in an indoor environment is the multipath propagation problem. Multipath propagation occurs when signals reflects and refract from an object, changing the signals characteristics. READ MORE
