WebAn LDPC code is ( j, k) - regular if the parity-check matrix has a fixed number of j nonzero entries in each row and k entries in each column; otherwise, the LDPC code is irregular. The dual of an LDPC code has a sparse generator matrix and is called an LDGM code. A parity check is performed by taking the inner product of a row of the parity ...
