Abstract
A method for low density parity check (LDPC) encoding comprises concatenating a predetermined number of zero bits to a scrambled input data word to generate a concatenated binary sequence; computing parity bits to be added to the concatenated binary sequence, wherein the computing is performed using an LDPC encoder; producing an encoded codeword that consists of the concatenated binary sequence and the parity bits; and replacing the predetermined number of zero bits in the encoded codeword with a scrambled binary sequence, thereby discarding the zero bits.
