  1. 1. 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

  3. 2. Signal-aware adaptive timeout in cellular networks : Analysing predictability of link failure in cellular networks based on network conditions

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Martin Larsson; Anton Silfver; [2017]
    Nyckelord :channel quality indicator; adaptive timeout; cellular networks; LTE;

    Sammanfattning : Cellular networks are becoming more common, this introduces new challenges in dealing with their error prone nature. To improve end-to-end performance when the first link in the connection is wireless, an adaptive timeout based on network conditions is constructed. LÄS MER

  4. 3. Performance Evaluation of Packet Scheduling Algorithms for LTE Downlink

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Sammanfattning : Long Term Evolution (LTE) of the Universal Mobile Telecommunications System (UMTS) is designed to revolutionize mobile broadband technology with key considerations of higher data rate, improved power efficiency, low latency and better quality of service. It promises high peak data rates of 100 Mbps downlink and 50 Mbps uplink transmissions and can operate in different bandwidths ranging from 1. LÄS MER

  5. 4. Fast Viterbi Decoder Algorithms for Multi-Core System

    Master-uppsats, KTH/Signalbehandling

    Författare :Zilong Ju; [2012]
    Nyckelord :Parallel algorithm; Viterbi algorithm; Tail biting convolutional code; Multi-core;

    Sammanfattning : In this thesis, fast Viterbi Decoder algorithms for a multi-core system are studied. New parallel Viterbi algorithms for decoding convolutional codes are proposed based on tail biting trellises. LÄS MER
