Abstract: A transmitter is provided. The transmitter includes: a Low Density Parity Check (LDPC) encoder configured to encode input bits to generate an LDPC codeword including the input bits and parity bits to be transmitted to a receiver in a current frame; a repeater configured to repeat, in the LDPC codeword, at least some bits of the LDPC codeword in the LDPC codeword so that the repeated bits are to be transmitted in the current frame; a puncturer configured to puncture some of the parity bits; and an additional parity generator configured to select at least some bits of the LDPC codeword including the repeated bits, and generate additional parity bits to be transmitted in a previous frame of the current frame.
