  1. 1. Power Focusing with Intelligent Reflective Surfaces for Wireless Indoor Communication Systems

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Mingye Gong; [2021]
    Nyckelord :Intelligent Reflective Surfaces IRS ; 6G; MISO; Wireless Indoor Communication Systems; Technology and Engineering;

    Sammanfattning : Intelligent reflective surfaces (IRS) are envisioned to have a significant number of applications in future wireless network systems by reconfiguring the signal propagation to improve system performance. In particular, the IRS's cell elements can independently reflect the incident signal by tuning its phase and achieving passive beamforming to enhance the received signal of the user equipment.
