Abstract
A low-density parity check (LDPC) decoder comprises a decoded data stream generator that generates a decoded data stream based on a received data stream and a set of matrix-based codewords. The matrix-based codewords form a LDPC parity check matrix H. A decoder control module at least one of prewrites or replaces a selected portion of at least one of the plurality of codewords with zeros prior to generation of the decoded data stream.
