Abstract:
A low density parity check (LDPC) encoder, an LDPC decoder, and an LDPC encoding method are disclosed. The LDPC encoder includes first memory, second memory, and a processor. The first memory stores an LDPC codeword having a length of 64800 and a code rate of 5/15. The second memory is initialized to 0. The processor generates the LDPC codeword corresponding to information bits by performing accumulation with respect to the second memory using a sequence corresponding to a parity check matrix (PCM).

Claim (Index 1):
A low density parity check (LDPC) decoder, comprising:\n a receiving unit configured to receive a signal corresponding to an LDPC codeword having a length of 64800 and a code rate of 5/15, the LDPC codeword encoded using a sequence corresponding to a parity check matrix (PCM), the sequence represented by the following Sequence Table; and a decoding unit configured to restore error-corrected bits from the received signal by performing decoding corresponding to the parity check matrix.
