6. 4. Early-Decision Decoding of LDPC Codes

   Author : Anton Blad; Oscar Gustafsson; Erik G. Larsson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ECC; LDPC; communication; coding; decoding; low-power; Tanner; iterative algorithms; Electronics; Elektronik;

   Abstract : Since their rediscovery in 1995, low-density parity-check (LDPC) codes have received wide-spread attention as practical capacity-approaching code candidates. It has been shown that the class of codes can perform arbitrarily close to the channel capacity, and LDPC codes are also used or suggested for a number of important current and future communication standards.

7. 5. Towards a Theory of Codes for Iterative Decoding

   Author : Michael Lentmaier; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bit error probability; low-density parity-check convolutional code; low-density parity-check code; turbo code; convolutional code; channel coding; iterative decoding; Informatics; systems theory; Informatik; systemteori;

   Abstract : Channel codes in combination with iterative decoding techniques are a both powerful and efficient method to protect data against disturbances in digital communication systems. This thesis deals with various code constructions for block-wise and continuous transmission that have the potential to achieve low bit error rates with iterative decoding, even when operating close to the Shannon limit.
