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. 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

4. 3. Performance evaluation of interleaving techniques for IEEE 802.15.4 transmissions

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

   Författare :Jiahuan Lei; Qingbi Liao; [2014]
   Nyckelord :interleaving; Matlab; Reed-Solomon; TinyOS; WSN; FEC; MicaZ;

   Sammanfattning : In the wireless sensor network, the WLAN interference, multi-path fading andattenuation are the main reason for packets’ corruption. Forward errorcorrection is one of the methods for error mitigation. Many coding methods aredesigned to improve the reliability of wireless channel. LÄS MER

5. 4. File-Based Delivery over LTE-Based MBMS

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Ravichandran Sivawamy; Geethanjali Soundappan; [2013]
   Nyckelord :RaptorQ; Raptor; AL-FEC; MBMS; FLUTE;

   Sammanfattning : One of the most important emerging aspects of Third Generation Partnership Project (3GPP) is the Multimedia Broadcast/Multicast Service (MBMS) aiming to deliver multimedia contents to mobile users more efficiently in point-to-multipoint way. 3GPP also recommends an Application Layer Forward Error Correction (AL-FEC) scheme, especially for MBMS, in order to provide reliable transmission over mobile networks.

7. 5. Decoding algorithms of Reed-Solomon code

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

   Författare :Szymon Czynszak; [2011]
   Nyckelord :Reed-Solomon code; decoding algorithms;

   Sammanfattning : Reed-Solomon code is nowadays broadly used in many fields of data transmission. Using of error correction codes is divided into two main operations: information coding before sending information into communication channel and decoding received information at the other side.
