  1. 21. Coverage Analysis and Cooperative Hybrid Precoding for 5G Cellular Networks

    Författare :Chao Fang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; millimeter wave; heterogeneous networks; 5G; beamforming;

    Sammanfattning : 5G innovations have been made in both the network deployment and the transceiver architectures in order to increase coverage, energy- and spectrum-efficiency. Future base stations (BSs) are expected to be densely deployed in places such as walls and lamp posts and cover a smaller area compared to current macro BS systems. LÄS MER

  3. 22. Spintronic and Electronic Oscillators for Magnetic Field Sensing and Ising Machines

    Författare :Dagur Ingi Albertsson; Ana Rusu; Johan Åkerman; Saul Rodriguez Duenas; Atila Alvandpour; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spintronic Oscillator; Behavioural Modeling; Macrospin Approximation; Magnetic Field Sensor; Ising Machine; Duffing Oscillator; Kuramoto Model; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Oscillators can exhibit a range of complex dynamics which are often encountered in nature. These characteristics include synchronization, injection locking, chaos, bifurcations, etc. To date, the applications of electronic oscillators has mostly been limited to communication systems.
