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 16200 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).
Claims5
A transmitter for a broadcast signal, comprising:
- an LDPC encoder configured to generate an LDPC codeword having a length of 16200 and a code rate of 5/15 by performing accumulation with respect to memory initialized to 0, using a sequence corresponding to a parity check matrix (PCM), the LDPC codeword corresponding to information bits;
- a modulator configured to perform modulation corresponding to the LDPC codeword in order to generate a modulated signal;
- and
- an antenna configured to transmit a transmission signal over a physical channel, the transmission signal being generated using the modulated signal corresponding to the LDPC codeword, the LDPC codeword including parity bits for correcting errors over the physical channel,
- wherein the sequence is represented by the following Sequence Table:
