Introduction to LDPC Codes - CMRR STAR

5/ 31/ 07 LDPC Codes 14 •Solution • Long, structured, “pseudorandom” codes • Practical, near-optimal decoding algorithms •Examples • Turbo codes (1993) • Low-density parity-check (LDPC) codes (1960, 1999) • State-of-the-art • Turbo codes and LDPC codes have brought Shannon limits to within reach on a wide range of channels.

LDPC Codes – a brief Tutorial - bernh

LDPC Codes – a brief Tutorial Bernhard M.J. Leiner, Stud.ID.: 53418L bleiner@gmail.com April 8, 2005 1 Introduction Low-density parity-check (LDPC) codes are a class of linear block LDPC codes. The name comes from the characteristic of their parity-check matrix which contains only a few 1’s in comparison to the amount of 0’s.
