Abstract:
A periodic Low Density Parity Check (LPDC) coding apparatus and method allows reference to an LDPC code parity check matrix, where such reference is accomplished row by row. A specially configured memory and cyclical shift operation are used by the apparatus to efficiently compute check equations of the periodic LDPC code.
