  1. 11. Non-Coherent Radio-Based Positioning

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Farshid Rezaei; Mohamad Abou Nasa; [2019]
    Keywords : target localization and tracking; wireless sensor network WSN ; hybrid measurements; received signal strength RSS ; angle of arrival AoA ; Technology and Engineering;

    Abstract : In this thesis, a new Angle-of-Arrival (AoA) technique is used to determine the direction of a target in an outdoor environment using Radio Frequency (RF) signals. This technique estimates the AoA based on the difference between the Received Signal Strength Indicators (RSSI) from two/four directive antennas. READ MORE

  3. 12. GNSS Timing Receiver Performance in Urban Canyons

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

    Author : Xiangcheng Fu; [2019]
    Keywords : GNSS Timing Receiver; 1PPS; Synchronization; Urban Canyon;

    Abstract : Time synchronization is critical for the operation of radio base stations (RBS) in telecommunication companies. Global navigation satellite system (GNSS) is an existing technology to provide precise timing information to distributed RBSs. READ MORE

  4. 13. The impact of metallic cranial implants on proton-beam radiotherapy treatment plans for near implant located tumours : A phantom study on the physical effects and agreement between simulated treatment plans and the resulting treatment for near implant located cranial tumours

    University essay from Umeå universitet/Institutionen för fysik

    Author : Adam Sjögren; [2018]
    Keywords : Proton-based Radiotherapy; Cranial implants; Titanium implants; Cancer treatment; metal streak artifacts.;

    Abstract : Within the field of radiotherapy treatments of tumour diseases, the hunt for more accurate and effective treatment methods is a continuous process. For some years ion-beam based radiotherapy, especially the proton-beam based applications, has increased in popularity and availability. READ MORE

  5. 14. Feasibility study of data transmission via HF link from a small UAV platform

    University essay from Uppsala universitet/Signaler och System

    Author : Filip Enander; [2017]
    Keywords : HF; High Frequency; UAV; Unmanned Aerial Vehicle; Radio Communication; Ionosphere; Communication system;

    Abstract : The High Frequency (HF) band, 3-30 MHz, is used when no infrastructure for long-range communications is available. New technology, such as digital signal processing enables higher data rate in the HF band, which in 2000s has resulted in increased commercial use. READ MORE

  6. 15. Indoor Radio Propagation Modelling with Antenna Placement Optimization

    University essay from Lunds universitet/Matematisk statistik

    Author : Fabian Ågren; [2017]
    Keywords : radio propagation modelling; dominant path model; dominant path; A*; Astar; thetastar; indoor radio planning; radio planning; Mathematics and Statistics;

    Abstract : The use of wireless communication has grown rapidly over the last three decades. The Swedish Post and Telecom Authority estimates that more than 80% of all mobile traffic is received or transmitted from within buildings and the number is expected to reach over 90% in the near future.
