  1. 1. 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

  3. 2. 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

  4. 3. 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

  5. 4. 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

  6. 5. Channel Quality Information Reporting and Channel Quality Dependent Scheduling in LTE

    University essay from Institutionen för systemteknik

    Author : Erik Eriksson; [2007]
    Keywords : LTE; Scheduling; CQI; Channel dependent;

    Abstract : Telecommunication systems are under constant development. Currently 3GPP is working on an evolution of the 3G-standard, under the name 3G Long Term Evolution (LTE). Some of the goals are higher throughput and higher peak bit rates. A crucial part to achieve the higher performance is channel dependent scheduling (CDS). READ MORE
