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

    University essay from Linköpings universitet/Institutionen för datavetenskap

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

    Abstract : 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. READ MORE

  3. 2. Cross-subframe channel estimation for low-complexity devices in LTE

    University essay from KTH/Teknisk informationsvetenskap

    Author : Hugo Lime; [2017]
    Keywords : ;

    Abstract : One of the most critical issues of wireless communication systems is the timevaryingand frequency-selective channel. Knowledge about the channel greatlyimproves communication performance. It enables coherent demodulation andmeasurements of Signal to Noise Ratio (SNR) and Channel Quality Indicators(CQI). READ MORE

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

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Ömer Arslan; Olufemi Emmanuel Anjorin; [2012]
    Keywords : LTE; 3GPP; OFDMA; Downlink Scheduling; CQI;

    Abstract : 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. READ MORE

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

    University essay from KTH/Signalbehandling

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

    Abstract : 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. READ MORE

  6. 5. Investigation and development of a verification protocol test tool for LTE

    University essay from Institutionen för datavetenskap

    Author : Jolian Georgis; [2011]
    Keywords : LTE; MME; SGW; eNB; IoDT; LogTool; JAPY.;

    Abstract : At Ericsson IoDT test department testing tools are used to control the traffics between the EU and the eNB to check the typical problems issues. By storing these problems in a log file will help mobile vendors to eliminate the mentioned problems by developing solutions for more significant products. READ MORE
