  2. 1. Designing for the incorporation of programming in mathematical education : Programming as an instrument for mathematical problem solving

    Author : Andreas Borg; Kenneth Ruthven; Maria Fahlgren; Chantal Buteau; Karlstads universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematics; math; upper secondary; problem solving; programming; coding; instrument; instrumental genesis; education; mathematics education; scheme; matematik; skola; utbildning; problemlösning; programmering; kodning; instrument; instrumental genes; utbildning; matematikdidaktik; schema; Pedagogiskt arbete; Educational Work; Matematikdidaktik; Mathematics didactics;

    Abstract : This study explored Swedish upper secondary school students’ use of programming for mathematical purposes. The aim of the study was to investigate the process through which students learn how to use a programming environment as a technical artefact during mathematical problem solving and how the orchestration of such learning situations could facilitate this process.

    Abstract : Detta arbete börjar med att presentera en kodningssats gällande linjärkodning över ändliga ringar för kodning av korrelerade diskretaminneslösa källor. Denna sats inkluderar som specialfall motsvarandeuppnåbarhetssatser från Elias och Csiszár gällande linjär kodning överändliga kroppar. READ MORE

  6. 4. Codes on Graphs and More

    Author : Florian Hug; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convolutional codes; woven graph codes; Low-density parity-check LDPC codes; tailbiting codes; bit error probability; MacWilliams Identity;

    Abstract : Modern communication systems strive to achieve reliable and efficient information transmission and storage with affordable complexity. Hence, efficient low-complexity channel codes providing low probabilities for erroneous receptions are needed. READ MORE

  7. 5. Analysis of Some Convolutional Coding Constructions

    Author : Karin Engdahl; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo-codes; low-density parity-check convolutional codes; low-density codes; PSK; PAM; QAM; coded modulation; multilevel coding; convolutional codes; multilevel modulation; iterative decoding; Informatics; systems theory; Informatik; systemteori;

    Abstract : This thesis focuses on different convolutional coding constructions for digital communication systems, and on methods to analyze these constructions. The work presented in the thesis can be divided into three main areas; error probability bounds for convolutional codes, analysis of multilevel modulation, and investigation of low-density parity-check convolutional codes.
