  1. 16. Wireline Communications in a Wireless World

    Författare :Yezi Huang; Bredbandskommunikation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The whole society is digitalizing, filled with streaming services, cloud computing and an ambition of ubiquitous connectivity. To address the data demand, ultra-fast broadband, at the speeds of 1Gbps and more, is developed and deployed. Optical fibers have been long viewed as a future-proof carrier for the ultra-fast broadband. LÄS MER

  3. 17. A Statistical-Physics Approach to the Analysisof Wireless Communication Systems

    Författare :Maksym Girnyk; Lars K. Rasmussen; Giuseppe Caire; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless communications; statistical physics; random matrix theory; large-system analysis; MIMO; 5G; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Multiple antennas at each side of the communication channel seem to be vital for future wireless communication systems. Multi-antenna communication provides throughput gains roughly proportional to the smallest number of antennas at the communicating terminals. LÄS MER

  4. 18. 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.

  5. 19. Signal Processing Aspects of Massive MIMO and IRS-Aided Communications

    Författare :Özgecan Özdogan; Emil Björnson; Erik G. Larsson; Mari Kobayashi; 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, and it has been started to be commercially deployed in many countries. LÄS MER

  7. 20. Analysis of the Age of Information in Status Update Systems

    Författare :Antzela Kosta; Vangelis Angelakis; Nikolaos Pappas; Dán György; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Rapid advances in wireless technology have taken us towards a pervasively connected world in which a vast array of wireless devices, from mobile phones to environmental sensors, seamlessly communicate with each other. In some of these systems the freshness of the transmitted information is of high importance. LÄS MER
