Abstract
A signal receiving method include: demodulating a signal received from a transmitting apparatus to generate values based on 1024-quadrature amplitude modulation (QAM); splitting the values into a plurality of groups; deinterleaving the plurality of groups based on a preset interleaving order; and decoding 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, wherein the plurality of groups are deinterleaved based on a predetermined equation.
Claims2
A receiving method comprising:
- demodulating a signal received from a transmitting apparatus to generate values based on 1024-quadrature amplitude modulation (QAM);
- splitting the values into a plurality of groups;
- deinterleaving the plurality of groups based on an interleaving order;
- and
- decoding 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,
- wherein the plurality of groups are deinterleaved based on a following equation:
- Yπ(j)=Xj for(0≤j<Ngroup),
- where Xj is a j-th group among the plurality of groups, Yj is a j-th group among the deinterleaved plurality of groups, Ngroup is a number of the plurality of groups, and π(j) denotes the interleaving order, and
- wherein the π(j) is represented as follows:
