  1. 1. Extension of an Existing Simulator for Cellular Communication with Support for 5G NR : Porting of MIMO Channel Estimation Methods form a prototype to an existing Link-Level Simulator

    M1-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Författare :Majed Haj Hussein; Abdulsalam Alnahawi; [2022]
    Nyckelord :5G NR; Channel Estimation; MIMO; OFDM; DMRS;

    Sammanfattning : Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) are two efficient technologies used to achieve higher data rate, lowlatency, robustness against fading used in 5G New Radio (NR). At the receiver end,the data arrives distorted due to disturbance during transfer over the wireless channel. LÄS MER

  3. 2. Quantum Annealing Algorithms for PAPR Minimisation in Wireless Networks

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :David Bern; [2022]
    Nyckelord :Quantum Mechanics; Algorithms; Quantum Annealing; Graph representation;

    Sammanfattning : In this thesis, we devise a scheme to run PAPR minimisation with 3GPP EVM requirement as constraint on the D-Wave Systems’ quantum annealer. The PAPR minimisation is a problem central to optimising the costs and performance of wireless networks becoming increasingly difficult for larger OFDM-MIMO systems, while the EVM constraint needs to be satisfied to reach an industry standard performance.

  4. 3. Application of machine learning in 5G to extract prior knowledge of the underlying structure in the interference channel matrices

    Master-uppsats, KTH/Matematisk statistik

    Författare :Danilo Peng; [2019]
    Nyckelord :Machine learning; 5G; interference channel; blind source estimation; MIMO; OFDM; bandwidth prediction; support vector machines; artificial neural network.; Maskininlärning; 5G; interferencekanal; stödvektormaskin; neurala nätverk; brandbedd estimering;

    Sammanfattning : The data traffic has been growing drastic over the past few years due to digitization and new technologies that are introduced to the market, such as autonomous cars. In order to meet this demand, the MIMO-OFDM system is used in the fifth generation wireless network, 5G. LÄS MER

  5. 4. Reduction of Crosstalk Distortion in 5G

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Nyckelord :Wireless Communication; Power Amplifier; Linearization; Digital predisposition; 5G; Massive MIMO.; Technology and Engineering;

    Sammanfattning : Increasing demand for higher data rates in wireless communication systems has tremendously evolved over the last years. This demand is rapidly increasing with rising in number of wireless devices. LÄS MER

  7. 5. RF system for mmWave massive MIMO

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Ziqi Zhou; Jingwei Wang; [2018]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Due to rapid developments in communication technology, it is likely that 5G networks will be rolled out in 2019. To adapt to 5G, hardware will have to develop to meet the requirements of this new technology. The mmWave communication is one of the main elements of 5G technology. LÄS MER
