    Sammanfattning : With the increase in demand for compact and high data rate communication systems, there is a need for high efficiency with modulated signals (PAPR 5-10 dB) for base-station power amplifiers. One of the famous architectures used to achieve this is Doherty architecture. LÄS MER

  7. 5. Reinforcement Learning for Link Adaptation in 5G-NR Networks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Evagoras Makridis; [2020]
    Nyckelord :;

    Sammanfattning : The Adaptive Modulation and Coding (AMC) scheme in the link adaptation is a core feature in the current cellular networks. In particular, based on Channel Quality Indicator (CQI) measurements that are computed from the Signal-to-Interference-plus-Noise Ratio (SINR) level of User Equipment (UE), the base station (e.g. LÄS MER
