  1. 6. Signal Processing Aspects of Cell-Free Massive MIMO

    Författare :Giovanni Interdonato; Erik G. Larsson; Hien Quoc Ngo; Tommy Svensson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The fifth generation of mobile communication systems (5G) promises unprecedented levels of connectivity and quality of service (QoS) to satisfy the incessant growth in the number of mobile smart devices and the huge increase in data demand. One of the primary ways 5G network technology will be accomplished is through network densification, namely increasing the number of antennas per site and deploying smaller and smaller cells.

  3. 7. Analysis of Cellular and Cell-Free Massive MIMO with Rician Fading

    Författare :Özgecan Özdogan; Emil Björnson; Erik G. Larsson; Sofie Pollin; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The data traffic in cellular networks has grown at an exponential pace for decades. This trend will most probably continue in the future, driven by new innovative applications. One of the key enablers of future cellular networks is the massive MIMO technology. A massive MIMO base station is equipped with a massive number (e. LÄS MER

  4. 8. Intrinsically Disordered Domains of the B Cell Receptor Cell-Free Expression and Characterization by NMR

    Författare :Linnéa Isaksson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap;

    Sammanfattning : After the last twenty years of research, the occurrence of flexible proteins without a fixed three-dimensional structure are no longer considered to be rare exceptions from the structure-function paradigm. Instead, intrinsically disordered proteins (IDPs) have become one of the most interesting subjects of modern protein research. LÄS MER

  5. 9. Immune maturation and lymphocyte characteristics in relation to early gut bacteria exposure

    Författare :Sophia Björkander; Eva Sverremark Ekström; Hanne Frøkiær; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Allergy; cell-free supernatant; chemokines; colonization; cytokines; FOXP3; immune-maturation; lactobacilli; lymphocytes; NK-cells; Staphylococcus aureus; unconventional T-cells; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : At birth, the immune system is immature and the gut microbiota influences immune maturation. Staphylococcus aureus (S. aureus) and lactobacilli are part of the neonatal gut microbiota and have seemingly opposite effects on the immune system. S. LÄS MER

  7. 10. Beyond Massive MIMO : Trade-offs and Opportunities with Large Multi-Antenna Systems

    Författare :Juan Vidal Alegría; Kommunikationsteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIMO; massive MIMO; cell-free massive MIMO; Decentralized multi-antenna architectures; Decentralized schemes; WAX decomposition; LIS; Reconfigurable surfaces; RIS; IRS; ARIS; FRIS;

    Sammanfattning : After the commercial emergence of 5G, the research community is already putting its focus on proposing innovative solutions to enable the upcoming 6G. One important lesson put forth by 5G research was that scaling up the conventional multiple-input-multiple-output (MIMO) technology by increasing the number of antennas could be extremely beneficial for effectively multiplexing data streams in the spatial domain.
