  1. 1. Lean Beam Management for New Radio

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

    Author : Nawanit Kumar; [2020]
    Keywords : 5G; NR; MIMO; Beam management; CSI-RS; Technology and Engineering;

    Abstract : The use of millimetre-wave frequencies in Fifth generation New Radio has lead to high path loss due to radio propagation environment. Simultaneously, high data rates is a must for current products due to high market demand. This requirement accounts for efficient tracking of the best beam for the user equipment to stay connected to it. READ MORE

    Abstract : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. READ MORE

  3. 3. Characterization of Passive Intermodulation Distortion in MultiBand FDD Radio Systems

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

    Author : Tomás Soares da Costa; [2019]
    Keywords : ;

    Abstract : Intermodulation distortion (IMD) is a phenomenon that results in generation of spurious distortion signals when two or more signals of different frequencies pass through a nonlinear system. In general, IMD occurs in active circuits of a radio system, however, passive wireless components such as filters, transmission lines, connectors, antennas, attenuators etc. READ MORE

  4. 4. Nonlinear effects and predictions in advanced antenna systems in 5G Distortion Effects in 5G

    University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Author : Altahra Mohammed; [2019]
    Keywords : PA; DPD; Active load-pull; Calibration.;

    Abstract : In the next-generation wireless cellular communication systems known as 5G, radio equipment will be deployed in several frequency bands, among them is the millimeter wave bands (26 - 40 GHz). The use of these high frequencies can help to mitigate the limited spectrum problem and higher data rates can be achieved [2] . READ MORE
