Claim:
1. An apparatus for decoding a low density parity check (LDPC) code, the apparatus comprising: a memory configured to receive a LDPC codeword having a length equal to a lifting factor times a base LDPC code length, wherein the lifting factor is greater than one; and a number of LDPC processing elements configured to decode the LDPC codeword, wherein each of the number of LDPC processing elements decode separate portions of the LDPC codeword, wherein, when the LDPC processing elements decode in parallel, a first LDPC processing element in the LDPC processing elements is configured to receive the LDPC codeword and decode a fraction of a total number of rows in the LDPC code, the fraction equal to one over the number of the LDPC processing elements.
