Claim 2:
3. A transmitting method comprising:
encoding input bits based on a low density parity check (LDPC) code to generate a codeword;
splitting the codeword into a plurality of bit groups;
interleaving the plurality of bit groups;
interleaving bits of the interleaved plurality of bit groups using a plurality of columns, each of the plurality of columns comprising a first part and a second part;
mapping the interleaved bits to constellation points; and
transmitting a signal which is generated based on the constellation points,
wherein some bit groups among the interleaved plurality of bit groups are interleaved in the first part and at least one remaining bit group is interleaved in the second part, and
wherein bits of the some bit groups and bits of the at least one remaining bit group are written in a first direction and are read out in a second direction different from the first direction.
