  1. 6. Improvement of the robustness and performance of time of arrival algorithms

    University essay from Uppsala universitet/Signaler och system

    Author : Kristian Huotila; [2021]
    Keywords : ;

    Abstract : 5G offers several new improvements compared to its predecessors, such as higher speeds, lower latency and larger capacity. In order to ensure this, time of arrival algorithms are used in the Radio Access Networks for several purposes. Some of them are 3D positioning of User Equipment and synchronization. READ MORE

  3. 7. A Study of Multipath Propagation and Doppler Effect at 24GHz ISM band

    University essay from Högskolan i Gävle/Elektronik

    Author : Shaikh Masud Rana; [2020]
    Keywords : Multipath Propagation; Doppler Effect; 24GHz; ISM Band;

    Abstract : The wideband channel has been analyzed at the University of Gävle by using millimeter-wave (mm-Wave) frequency for improving the fifth-generation (5G) in Radio-frequency (RF) characterization. The proposed mm-Wave frequency is 24GHz, which is carried out from measurement testbed at the Robotics Lab. READ MORE

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

    Author : Axel Berg; [2017]
    Keywords : IoT NB-IoT OTDOA Positioning; Technology and Engineering;

    Abstract : This thesis considers the problem of improving the performance of observed time difference of arrival (OTDOA) based positioning for Narrowband Internet of Things (NB-IoT). A new iterative low-complexity algorithm based on expectation maximization successive interference cancellation (EM-SIC) is presented. READ MORE

  6. 10. Enhancements in LTE OTDOA Positioning for Multipath Environments

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Ivar Olofsson; [2016]
    Keywords : positioning; TDOA; NLOS bias; multiple TOA candidates; probabilistic method; ML estimation; LTE; simulation;

    Abstract : By using existing radio network infrastructure, a user can be positioned even where GPS and other positioning technologies lack coverage. The LTE Positioning Protocol (LPP) supports user Reference Signal Time Difference (RSTD) reports based on the Time of Arrival (TOA) for a Positioning Reference Signal (PRS). READ MORE
