1. A receiver comprising:
a signal receiver configured to receive a superposition-coded signal;
a first decoder configured to decode data of the superposition-coded signal to generate information bits corresponding to a first layer signal of the superposition-coded signal based on at least part of a parity check matrix of a low density parity check (LDPC) code;
an encoder configured to encode the information bits and first parity bits to generate second parity bits based on the at least part of the parity check matrix;
an interleaver configured to interleave bits of a codeword comprising the information bits, the first parity bits and the second parity bits;
a mapper configured to map the interleaved bits of the codeword to constellation points; and
a second decoder configured to decode data of a second layer signal to generate bits corresponding to the second layer signal,
wherein the second layer signal is obtained by removing a signal which is generated based on the constellation points, from the superposition-coded signal, and
wherein the parity check matrix comprises a dual diagonal matrix corresponding to the first parity bits and an identity matrix corresponding to the second parity bits.
