  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

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Materialteori

    Author : David Bern; [2022]
    Keywords : Quantum Mechanics; Algorithms; Quantum Annealing; Graph representation;

    Abstract : 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.
