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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Evagoras Makridis; [2020]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 22. Bi-directional Low Pass Filter and Mixer Design

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sharath Thandava Murthy; Meshach Milon Paul Pear Pradeep Kumar; [2020]
    Keywords : Technology and Engineering;

    Abstract : This report presents the research and implementation of a bidirectional filter and mixer combination for the transceiver chain in 5G TDD equipment. The main objective of this project is to find a feasible design for mixer and low pass filter to reuse the same hardware blocks for both transmitter and receiver chain. READ MORE

  4. 23. A Study of Multipath Propagation and Doppler Effect at 24GHz ISM band

    University essay from Högskolan i Gävle/Elektronik

    Author : Shaikh Masud Rana; [2020]
    Keywords : Multipath Propagation; Doppler Effect; 24GHz; ISM Band;

    Abstract : The wideband channel has been analyzed at the University of Gävle by using millimeter-wave (mm-Wave) frequency for improving the fifth-generation (5G) in Radio-frequency (RF) characterization. The proposed mm-Wave frequency is 24GHz, which is carried out from measurement testbed at the Robotics Lab. READ MORE
