  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. Improving Spatial Sound Capturing on Mobile Devices Through Fusion of Inertial Measurement Data

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Pouya Ashraf; [2018]
    Keywords : ;

    Abstract : Through the use of sensor arrays it is possible to extract spatial information about signals present in the environment. For instance position, velocity, distance, etc. READ MORE

  4. 13. Performance Assessment of Massive MIMO Systems for Positioning and Tracking of Vehicles in Open Highways

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Markus Petersson; [2017]
    Keywords : massive MIMO; MIMO; positioning; tracking;

    Abstract : The next generation of mobile networks (5G) is currently being standardized, and massive MIMO (Multiple-Input-Multiple-Output) is a strong candidate to be part of this standard. Other than providing higher data rates and lower latency, high accuracy positioning is also required. READ MORE

  5. 14. Feasibility Study for Single Platform Airborne FDOA and TDOA Estimation With Unknown Source

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Alexander Karlsson; [2016]
    Keywords : ;

    Abstract : Direction of arrival (DOA) estimation is a well studied topic and used in many different applications. Although it is usually based on time-difference-of-arrival (TDOA) of coherent signals, it is sometimes possible to also use frequency-difference-of-arrival (FDOA). By combining TDOA and FDOA a more reliable estimate of the DOA can be obtained. READ MORE

  6. 15. Multi-Frequency Direction of Arrival Estimation by Low-Rank Approximation

    University essay from Lunds universitet/Matematik LTH

    Author : Linus Jangland; [2016]
    Keywords : Direction of arrival estimation; Hankel matrices; low rank; optimization; Mathematics and Statistics;

    Abstract : We consider the problem of estimating the location of a number of wave-emitting sources, known as the direction of arrival problem. We consider both the two- and three-dimensional case. The method we use works for equally as well as unequally spaced sensors, that are located in (possibly) non-square regions. READ MORE
