Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 3:
4. A receiving method comprising:
receiving a signal from a transmitting apparatus;
demodulating the signal to generate values based on quadrature phase shift keying (QPSK) modulation;
inserting predetermined values;
splitting the values and the inserted predetermined values into a plurality of groups;
deinterleaving some groups among the plurality of groups based on a permutation order; and
decoding values of the plurality of groups in which the some groups are deinterleaved based on a low density parity check (LDPC) code, a code rate being 3/15 and a code length being 16200 bits,
wherein the predetermined values correspond to parity bits punctured in the transmitting apparatus,
wherein the parity bits punctured in the transmitting apparatus are determined based on the permutation order and a number of parity bits to be punctured, and
wherein values of 20th, 24th, 44th, 12th, 22nd, 40th, 19th, 32nd, 38th, 41st, 30th, 33rd, 14th, 28th, 39th and 42nd among the deinterleaved plurality of groups comprise at least a part of the predetermined values.
