Abstract:
A receiving apparatus includes: a first decoder configured to decode a signal transmitted through a first layer from a layered division multiplexing (LDM) signal using a parity check matrix to generate low density parity check (LDPC) information word bits and parity bits; an encoder configured to encode the LDPC information word bits, generated by decoding the signal transmitted through the first layer, using the parity check matrix to generate parity bits corresponding only to preset columns in the parity check matrix; and a second decoder configured to decode a signal obtained by removing, from the LDM signal, a signal corresponding to the LDPC information word bits generated by decoding the signal transmitted through the first layer, the parity bits generated by the encoder, and the parity bits generated by the first decoder except the parity bits generated by the encoder, thereby to generate information word bits transmitted through a second layer.

Claim (Index 8):
A method of a receiving apparatus receiving and decoding a layered division multiplexing (LDM) signal which is generated based on a first layer and a second layer, the method comprising:\n decoding the LDM signal based on a parity check matrix comprising a plurality of columns to generate first information bits and first parity bits transmitted through the first layer, each of the first parity bits corresponding to each of the plurality of columns; encoding the first information bits based on the parity check matrix to generate second parity bits corresponding to predetermined columns among the plurality of columns; and decoding a signal obtained by removing, from the LDM signal, a signal which is generated based on the first information bits, one or more parity bits of the first parity bits except parity bits corresponding to the predetermined columns, and the second parity bits, to generate second information bits transmitted through the second layer.
