  3. 17. Simulation-Based Stochastic Blockage Model for Millimeter-wave Communication

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

    Author : Mihret Getye Sidelel; [2020]
    Keywords : ;

    Abstract : Recently, the growing demand for high data rates in wireless communication, together with the scarcity of spectrum in existing microwave bands, has motivated the use of millimeter-wave (mmWave) bands for 5G and future wireless communications. Even though mmWaves are potential candidates for fulfilling this rising demand, they come along with their own drawbacks that need to be addressed. READ MORE

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

    Author : Yan Shu; Yujie Zhang; [2020]
    Keywords : Technology and Engineering;

    Abstract : This master thesis aims to investigate downlink positioning techniques and improve fifth-generation (5G) cellular positioning performance in the indoor office scenario. In the thesis work, we target in the indoor office scenario because it is a typical deployment scenario standardized in 3GPP release 16. READ MORE

  5. 19. 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

  6. 20. 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.
