  1. 1. On the Design of Turbo Codes

    University dissertation from Department of Applied Electronics, Lund University

    Author : Johan Hokfelt; Lunds universitet.; Lund University.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channel coding; concatenated codes; convolutional codes; iterative decoding; interleaver design; trellis termination; Electronics; Turbo codes; Elektronik;

    Abstract : This thesis is about Turbo codes - codes constructed via parallel concatenation of two recursive convolutional encoders linked by an interleaver. The focus of the work is on the understanding and design of Turbo codes. READ MORE

  2. 2. Holistic approach in engineering design - controlling risks from accidental hazards in bridge design

    University dissertation from Lund University (Media-Tryck)

    Author : Ivar Björnsson; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design; codes; accidental; extreme; bridges; holistic; approach; robustness; risk; reliability; uncertainty;

    Abstract : Popular Abstract in English A central requirement in the design of bridge, or any structure, is that they are safe and do not fail unexpectedly. To ensure that such occurrences are acceptably rare involves predicting the various ways in which the bridge can fail and ensuring that provisions are made to prevent or control these potential failure.

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

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Christian Häger; [2016]
    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.

  5. 5. Designing Space-Time Codes Using Orthogonal Designs

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Girish Ganesan; Uppsala universitet.; Uppsala universitet.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Space-time codes; Orthogonal designs; Amicable orthogonal designs; Differential detection; Trellis codes; Turbo codes; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling; Signal Processing; Signalbehandling;

    Abstract : This thesis deals with coding schemes for systems with multiple transmit antennas. The problem of finding optimal transmission schemes for the case when the transmitter knows the channel and the case when the transmitter does not know the channel are considered. READ MORE
