  2. 1. Iteratively Decodable Convolutional Codes: Analysis and Implementation Aspects

    Author : Alberto Jimenez Feltström; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; systems theory; Informatics; Intersymbol Interference; BPSK; Product Codes; Braided Codes; Low-Density Parity-Check Codes; Convolutional Codes; Iterative Decoding; Informatik; systemteori; Systems engineering; computer technology; Data- och systemvetenskap;

    Abstract : This thesis addresses the theory and implementation aspects of iteratively decodable codes. Iteratively decodable codes include, in particular, Gallager's regular low-density parity-check (LDPC) codes, Tanner's generalized LDPC (GLDPC) codes, turbo codes due to Berrou et. al. and expander codes.

  4. 2. Analysis and Design of Spatially-Coupled Codes with Application to Fiber-Optical Communications

    Author : Christian Häger; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bit mapper; generalized product codes; generalized low-density parity-check codes; bounded-distance decoding; density evolution; spatial coupling; staircase codes.; braided codes; Bit-interleaved coded modulation;

    Abstract : The theme of this thesis is the analysis and design of error-correcting codes that are suitable for high-speed fiber-optical communication systems. In particular, we consider two code classes. The codes in the first class are protograph-based low-density parity-check (LDPC) codes which are decoded using iterative soft-decision decoding.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; product-like codes; bounded distance decoding; staircase codes.; product codes; hard decision decoding; generalized minimum distance decoding; probabilistic shaping; coded modulation; Achievable information rates;

    Abstract : The advent of the Internet not only changed the communication methods significantly, but also the life-style of the human beings. The number of Internet users has grown exponentially in the last decade, and the number of users exceeded 3.4 billion in 2016. READ MORE

  6. 4. Nuclear data uncertainty propagation for a lead-cooled fast reactor: Combining TMC with criticality benchmarks for improved accuracy

    Author : Erwin Alhassan; Henrik Sjöstrand; Rochman Dimitri; Michael Österlund; Stephan Pomp; Christophe Demaziere; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad kärnfysik; Applied Nuclear Physics;

    Abstract : For the successful deployment of advanced nuclear systems and for optimization of current reactor designs, high quality and accurate nuclear data are required. Before nuclear data can be used in applications, they are first evaluated, benchmarked against integral experiments and then converted into formats usable for applications. READ MORE
