  1. 1. Improving Dependability of Space-Cloud Payload Processor by Storage System

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Hassan Said; Stephanie Liza Johansson; [2023]
    Nyckelord :Fault tolerant; Markov analysis; Onboard processing; SSD array architecture; SSD; EDAC; RAID; Hamming code; Reed Solomon; Dependability evaluation; File systems; ZFS; Ext4.;

    Sammanfattning : Due to the usage of complicated platforms and current high-performance space computing technology, onboard processing in small satellites is expanding. Space-cloud payload processors with Commercial Off-The-Shelf (COTS) components, that are required to be radiation-tolerant, are used to perform the onboard processing. LÄS MER

  3. 2. Reed-Solomon Codes - Error Correcting Codes

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)

    Författare :Isabell Skoglund; [2020]
    Nyckelord :;

    Sammanfattning : In the following pages an introduction of the error correcting codes known as Reed-Solomon codes will be presented together with different approaches for decoding. This is supplemented by a Mathematica program and a description of this program that gives an understanding in how the choice of decoding algorithms affect the time it takes to find errors in stored or transmitted information.

  5. 4. Software based memory correction for a miniature satellite in low-Earth orbit

    Kandidat-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :John Wikman; Johan Sjöblom; [2017]
    Nyckelord :Software based memory correction; DRAM; Reed-Solomon; Hamming; CubeSat; Low-Earth Orbit; MIST;

    Sammanfattning : The harsh radiation environment of space is known to cause bit flips in computer memory. The conventional way to combat this is through error detection and correction (EDAC) circuitry, but for low-budget space missions software EDAC can be used. LÄS MER

  7. 5. Performance Evaluation of Error Correcting Techniques for OFDM Systems

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för kommunikationssystem

    Författare :Yasir Javed Qazi; Jawad Ahmed Malik; Safwan Muhammad; [2014]
    Nyckelord :OFDM; Linear block codes; Convolution codes; Reed-Solomon codes;

    Sammanfattning : Orthogonal frequency-division multiplexing (OFDM) systems provide efficient spectral usage by allowing overlapping in the frequency domain. Additionally, they are highly immune to multipath delay spread. LÄS MER
