1. A transmitter for a broadcast signal, comprising:
an LDPC (Low Density Parity Check) encoder configured to generate an LDPC codeword having a length of 64800 and a code rate of 7/15 by performing accumulation with respect to memory using a sequence corresponding to a parity check matrix (PCM), the LDPC codeword corresponding to information bits;
a modulator configured to generate a modulated signal corresponding to the LDPC codeword; and
an antenna configured to transmit a transmission signal corresponding to the modulated signal,
wherein the sequence is represented by the following Sequence Table:
