  1. 1. CRC Aided List Decoding of Convolutional Codes

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Mingzhe Guo; [2019]
    Nyckelord :channel coding; convolutional code; list decoding; CRC; 5G; Technology and Engineering;

    Sammanfattning : Designing for the best combination of channel codes and the decoding algorithm has always been a popular topic in channel coding. As a decoding algorithm for convolutional codes, Viterbi algorithm provides the most reliable performance with high complexity. LÄS MER

  2. 2. Tracking of Ground Vehicles : Evaluation of Tracking Performance Using Different Sensors and Filtering Techniques

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Marcus Homelius; [2018]
    Nyckelord :GNSS aided INS; Sensor Fusion; Tracking; Ground Vehicles; Map Matching; Viterbi Algorithm; RTS Smoother;

    Sammanfattning : It is crucial to find a good balance between positioning accuracy and cost when developing navigation systems for ground vehicles. In open sky or even in a semi-urban environment, a single global navigation satellite system (GNSS) constellation performs sufficiently well. LÄS MER

  3. 3. Map change detection using GPS position data

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Lina Sjöstrand; Fanny Andersson; [2018]
    Nyckelord :autonomous driving; change detection; map inference; GPS; road network; HMM; Viterbi algorithm; OSM; map matching; crowd-sourced data; update maps; Technology and Engineering;

    Sammanfattning : Technology advancement in autonomous driving is accelerating. For the technology to be safe it is crucial for the vehicles to have an updated map, meaning all vehicles should have a correct and identical representation of the current road network. LÄS MER

  4. 4. A Layered Two-Step Hidden Markov Model Positioning Method for Underground Mine Environment Based on Wi-Fi Signals

    Master-uppsats, Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

    Författare :Junyi Yu; [2015]
    Nyckelord :Underground mine environment; Indoor location; Layered two-step Hidden Markov Model; Viterbi algorithm;

    Sammanfattning : The safety of miners is of interest to all countries. In the event of a coal mine disaster, how to locate the miners remains the biggest and most urgent issue. The aim of this study is to propose a precise positioning method for underground mine environments to a low cost and with acceptable accuracy. LÄS MER

  5. 5. Low complexity algorithms for faster-than-Nyquistsign : Using coding to avoid an NP-hard problem

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Emil Ringh; [2013]
    Nyckelord :;

    Sammanfattning : This thesis is an investigation of what happens when communication links are pushed towards their limits and the data-bearing-pulses are packed tighter in time than previously done. This is called faster-than-Nyquist (FTN) signaling and it will violate the Nyquist inter-symbol interference criterion, implying that the data-pulsesare no longer orthogonal and thus that the samples at the receiver will be dependent on more than one of the transmitted symbols.
