  1. 21. 5G Positioning using Machine Learning

    University essay from Linköpings universitet/Reglerteknik

    Author : Magnus Malmström; [2018]
    Keywords : 5G; Positioning; Non Line of Sight NLOS ; Urban Canyons; Machine Learning; Neural Networks; Random Forest; Detection; Neyman-Person; Generalized Likelihood Ratio Test; Kalam Filter;

    Abstract : Positioning is recognized as an important feature of fifth generation (\abbrFiveG) cellular networks due to the massive number of commercial use cases that would benefit from access to position information. Radio based positioning has always been a challenging task in urban canyons where buildings block and reflect the radio signal, causing multipath propagation and non-line-of-sight (NLOS) signal conditions.

    Abstract : Humanity has been fishing for a long time, more specifically underice with nets, this could be a lot more efficient if it could beautomated in any stage of the procedure. The project aim is toconstruct an automated system for assisting in net fishing under ice. READ MORE

  4. 23. User Configurable Indoor Positioning System using WiFi Trilateration and Fingerprinting

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Anton Carlsson; Filip Gölander; Fredrik Sandelin; [2017]
    Keywords : wifi; trilateration; fingerprinting; rssi; indoor positioning; positioning system; Indoor localization;

    Abstract : The use of smartphones for positioning and navigation is mostly limited to outdoor settings. Indoors, where GPS signals are too inaccurate for positioning, an alternative must be used. READ MORE

  5. 24. GNSS Interference Localization Through PDOA-Methods

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Max Nyström; [2017]
    Keywords : GPS; GNSS; PDOA;

    Abstract : As GPS signals are of low power, the receiving end is always highly susceptible to interference, both unintentional and deliberate. As such there is a need to develop practical ways of detecting and localizing interference sources. READ MORE

  6. 25. Research and implementation of an indoor positioning algorithm

    University essay from Mittuniversitetet/Avdelningen för informationssystem och -teknologi

    Author : Honggang Liu; [2017]
    Keywords : Wireless sensor network; Indoor positioning; Wi-Fi; ZigBee;

    Abstract : The goal of the Internet of Things’ sensing technology is to provide LBS(location-based services); a key technology is finding out how to positioning the sensing devices. For positioning outdoors, mature tech-nology such as GPS and cellular network location can be used. READ MORE
