A method for low-density parity-check (LDPC) encoding of data comprises defining
a first MN parity check matrix; generating, based on the first parity check
matrix, a second parity check matrix having an MM triangular sub-matrix;
and, mapping the data into an LDPC code word based on the second parity check matrix.
The method is particularly useful for data communications applications, but may
also be employed in other applications such as, for example, data storage.
