5 Claims

1. A receiving apparatus comprising:

a demodulator configured to demodulate a signal received at the receiving apparatus from a transmitting apparatus to generate values based on 16-quadrature amplitude modulation (QAM), the signal carrying broadcast data;

a deinterleaver configured to deinterleave the values, split the deinterleaved values into a plurality of groups, and deinterleave the plurality of groups; and

a decoder configured to decode values of the deinterleaved plurality of groups based on a low density parity check (LDPC) code, a code rate of the LDPC code being 6/15 and a code length of the LDPC code being 64800 bits, wherein the decoded values correspond to the broadcast data,

wherein the plurality of groups are deinterleaved based on a following equation:

Yπ(j)=Xj for 0≤j<Ngroup,

where Xj is a jth group among the plurality of groups, Yj is a jth group among the deinterleaved plurality of groups, Ngroup is a number of the plurality of groups, and π(j) denotes an interleaving order for the deinterleaving of the plurality of groups, and

wherein the π(j) is represented as follows:


interleaving order π(j) (0 ≤ j ≤ 180)
