  1. 16. Performance Analysis Of Massive MIMO With Port Reduction

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

    Author : Tingrui Zhang; [2022]
    Keywords : 5G NR; Massive MIMO; Fronthaul; Beamforming; Functional split; 5G NR; Massive MIMO; Fronthaul; Beamforming; funktionell uppdelning;

    Abstract : In centralized radio access network (C-RAN) architecture, the base-band unit (BBU) is connected to one or more remote radio units (RRUs) via a fronthaul (FH) interface. Upgrading base station antennas in C-RAN to support massive multiple-input multiple-output (MIMO) technology can improve network spectral efficiency and largely boost the capacity of the 5G system.

  3. 17. Efficient High-level Synthesis Implementation of massive MIMO Processing on RFSoC

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

    Author : Sijia Cheng; [2022]
    Keywords : Technology and Engineering;

    Abstract : Massive multiple-input multiple-output (MIMO) refers to a wireless access technology that equips base station (BS) with hundreds to thousands of antennas to serve tens of user equipment (UE) in the same time-frequency resource. These extensive antennas improve spectral and energy efficiency, but the detection algorithms tend to be more complex with operations, multiplications, and inversions on larger size matrix.

  4. 18. NLP-based Failure log Clustering to Enable Batch Log Processing in Industrial DevOps Setting

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Ali Homayouni; [2022]
    Keywords : natural language processing; failure clustering; nightly testing; industrial devops;

    Abstract : The rapid development, updating, and maintenance of industrial software systems have increased the necessity for software artifact testing. Some medium and large industries are forced to automate the test analysis process due to the proliferation of test data. READ MORE

  5. 19. Modelling of contacts in Adams flex bodies using Mamba

    University essay from KTH/Fordonsdynamik

    Author : Shashwat Joshi; [2021]
    Keywords : Contact simulation; Mamba; Joint Interface Modes; Leaf spring modelling; Frame-subframe contact; ODS analysis; PSD; Kontaktsimulering; Mamba; gemensamma gränssnittslägen Joint Interface Modes ; bladfjädermodellering; ram-subramkontakt; ODS analys; PSD;

    Abstract : Simulations are a powerful tool used to reduce development time and cost in the vehicle industry. However, the models used in simulations are simplifications of reality, and there are commonly contradicting requirements between accuracy and computational efficiency. READ MORE

  6. 20. Physical Layer Security With Active Jamming Using NOMA.

    University essay from Blekinge Tekniska Högskola

    Author : Mounika Polisetti; [2021]
    Keywords : Physical Layer security; secrecy capacity; eavesdropper; spectral efficiency; secure NOMA transmission;

    Abstract : This paper is persuaded to understand the physical layer security in wireless commu-nications utilizing NOMA (Non Orthogonal Multiple Access) concepts in the presence of an eavesdropper. Physical layer security maintains the confidentiality and secrecyof the system against eavesdroppers. READ MORE
