Claim:
1. A transmitting apparatus comprising: an encoder configured to generate a codeword comprising input bits and parity bits, wherein the parity bits are generated based on a Low Density Parity Check (LDPC) code according to a code rate of 5/15 and a code length of 16200; an interleaver configured to split the codeword into a plurality of bit groups and interleave the plurality of bit groups to provide an interleaved codeword; and a mapper configured to demultiplex the interleaved codeword into data cells and map the data cells onto constellation points based on 256-QAM scheme, wherein the interleaver is configured to interleave the plurality of bit groups using a following equation: where X wherein the π(j) is defined as the table below:
