  1. 1. Tales of Tailbiting Codes

    University dissertation from Department of Information Technology, Lund Univeristy

    Author : Marc Handlery; Lunds universitet.; Lund University.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; minimum distance; maximum-likelihood decoding algorithm; active distance; woven convolutional code; tailbiting termination method; convolutional code; tailbiting code; Informatics; systems theory; Informatik; systemteori;

    Abstract : Tailbiting codes are error correcting codes and can be used in digital transmission systems. They are obtained by terminating convolutional codes into block codes. This thesis consists of an introduction to convolutional and tailbiting codes, and the Papers A--G that include the main results. READ MORE

  2. 2. On the Construction and Analysis of Iteratively Decodable Codes

    University dissertation from Department of Information Technology, Lund Univeristy

    Author : Dmitri Truhachev; Lunds universitet.; Lund University.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; minimum distance; Computer science; cycles; asymptotic performance; turbo codes; iterative decoding; low-density parity-check codes; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

    Abstract : Iterative decoding methods allow efficient decoding of long codes that are composed of smaller component codes. As a result reliable communication can be achieved with low decoding complexity even for rates close to Shannon capacity. This makes iteratively decodable codes a very attractive object of study in modern coding theory. READ MORE

  3. 3. On Spectrally Efficient Continuous Phase Modulation

    University dissertation from Chalmers University of Technology

    Author : Tommy Svensson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikation; Telecommunication; continuous phase modulation CPM ; reduced complexity detectors; additive white Gaussian noise {AWGN} ; adjacent channel interference; co-channel interference; bandwidth efficiency; convolutional codes; minimum Euclidean distance; optimized phase pulses.;

    Abstract : Spectrally efficient partial response continuous phase modulation (CPM) for wireless links is considered. Continuous phase modulation defines constant envelope phase codes, which are advantageous when using non-linear amplifiers. READ MORE

  4. 4. Iranians in Sweden : economic, cultural and social integration

    University dissertation from Stockholm : Almqvist & Wiksell International

    Author : Hassan Hosseini-Kaladjahi; Stockholms universitet.; [1997]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economic integration; discrimination; segmentation; cultural distance; cultural integration acculturation ; cognitive acculturation; normative acculturation; social integration; association; counterculture; SOCIAL SCIENCES Social sciences Sociology; SAMHÄLLSVETENSKAP Socialvetenskap Sociologi; Sociology; sociologi;

    Abstract : This study explores three dimensions in the integration of Iranian immigrants in Sweden: economic, cultural and social. To test the generalisability of the ideas presented, and to place them in a wider framework the integration of Iranians has been compared with those of three other minorities: Chileans, Poles, and Finns.

  5. 5. Taming of the BEAST

    University dissertation from Electro and information technology

    Author : Maja Loncar; Lunds universitet.; Lund University.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tree search; Technological sciences; product codes; list distance; list decoding; list-based SISO decoding; ML decoding; MAP decoding; iterative decoding; ISI equalization; BEAST; block codes; Teknik; Signal processing; Signalbehandling;

    Abstract : Modern communication systems are designed to enable reliable and fast information transfer. Therefore, efficient channel coding and decoding strategies are needed, which guarantee sufficiently low probability of erroneous reception with affordable receiver complexity. READ MORE
