AN INTRODUCTION TO ERROR CORRECTING CODES Part 1
acsweb.ucsd.eduparity check equations can be written as a matrix called the parity check matrix and is denoted H. • The parity check matrix has r rows and n columns. • The i-j thentry (ith row and j column) in this parity check matrix, h i,j, is equal to 1 if and only if the jth component of a code word is contained in the ith parity check equation.
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).
