  1. 1. 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. 2. Security testing of the Zigbee communication protocol in consumer grade IoT devices

    University essay from Högskolan i Halmstad

  4. 3. Battery-free Visible Light Sensing

    University essay from Uppsala universitet/Avdelningen för datorteknik

    Author : Andreas Soleiman; [2019]
    Keywords : Networked embedded systems; Visible light sensing; RF backscatter; Energy harvesting;

    Abstract : In this thesis, we show that it is possible to design a battery-free light sensing system that can sense and communicate hand gestures while operating fully on harvested power from indoor light. We present two main innovations that push our system to tens of microwatts of power to enable battery-free operation. READ MORE

  5. 4. Evaluation and Improvement of Decentralized Congestion Control for Multiplatooning Application

    University essay from KTH/Radio Systems Laboratory (RS Lab)

    Author : Chumeng Bai; [2018]
    Keywords : Wireless vehicular communication; decentralized congestion control; cooperative awareness messages; multiplatooning; simulation; Trådlös fordonskommunikation; decentraliserad överbelastning kontroll; kooperativ medvetenhet meddelanden; multiplatooning; simulering;

    Abstract : Platooning has the potential to be a breakthrough in increasing road capacity and reducing fuel consumption, as it allows a chain of vehicles to closely follow each other on the road. When the number of vehicles increases, platoons will follow one another in what is referred to as multiplatooning. READ MORE
