Introduction to Low Density Parity Check Codes
www.jaist.ac.jpA low-density parity check (LDPC) code is a linear block code whose parity check matrix has a small number of one’s. The number of 1’s in an LDPC code’s matrix grows linearly with the size N. The number of 1’s in a regular-density matrix grows as N·(M-N).

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.
