Performance of low-density parity-check (LDPC) codes with maximum likelihood decoding (MLD) for solid burst erasures is discussed. The columns of the paritycheck matrix of LDPC codes are permuted to increase the distance between elements (DBEs) which are defined as a number of symbol positions between elements 1 at each row of the parity-check matrix. The column permutation method can change the burst erasure correction capabilities by both the sum-product decoding algorithm and MLD algorithm. We derive some properties and show from simulation results that large values of DBEs lead to good performance for MLD. 1.
